Video support in UEFI mode

Hello,
I recently switch to EFI boot interface with a GPT partitions table disk with ArchLinux. The efifb work correctly and is remplace by the radeondrmfb. Both work well. My problem is that I cannot use vesafb in EFI mode. Even with
radeon.modeset=0 video=vesafb
kernel parameters, it is always the efifb framebuffer who is in use. I try to set grub-efi-x86_64
set gfxmode=1366x768-32
set gfxpayload=keep
but the vesafb is nerver in use.
So, is the efifb the only available framebuffer in plus of Radeon KMS (I have an Ati card) in EFI mode? It look like if the vesafb is only for BIOS boot sheme.
The fglrx kernel module load, but the proprietary Ati Xorg driver fglrx do not work. It complain about a missing Section "Devices" in xorg.conf. With the xorg.conf
aticonfig --initial
configuration file, it do not work too. Radeon KMS is disabled and efifb is on. Nothing have been add or substract form the /etc/X11/xorg.conf.d/ directory.

Unfortunately, I did not save the Xorg.0.log of fglrx. So I only wrote what I remember because I had to reinstall the xf86-video-ati drivers to have X working.
I have only one problem with Radeon/KMS/Xorg drivers in EFI and BIOS modes. When I go in full screen mode (Ctrl_Alt+f) with qemu(-kvm), I get a white/black screen flicking. I have to Control-Backspace-Delete and go back to console. Any modification to xorg.conf, drirc or anything fail. Without Xorg Radeon 3D acceleration or with Xorg fbdev driver, there is no problem. My Amd/Ati card is
00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Trinity [Radeon HD 7520G]
The radeon kernel module use the ARUBA firmware.
The proprietary Ati drivers where working with Gentoo in BIOS mode on this laptop. It's the first and only time I try the proprietary Ati drivers with ArchLinux on this laptop. I am gone stay with the free drivers that I prefer anyway. Any hint is wellcome.
Thank-you for your help.

Video support: resolution, portrait mode and aspect ratio

I have been playing with a friend's PowerPC-based mini (while I wait for Leopard to come out) and have some pre-purchase questions:
1) Do the current Core 2 Duo mac mini models support the VESA standard Preset Timing Mode of 1680 x 1050? (That's not listed on his older mac mini and would affect my choice of monitor.)
2) Does the current mac mini support portrait mode with any monitor at all?
3) The specs list maximum resolutions of 1920 x 1200 (16:10) with DVI and 1920 x 1080 (16:9) with VGA. I'm guessing that is related to bandwidth of the cable and does not mean that all output to DVI would be at the 16:10 aspect ratio and all output to VGA would be at the 16:9.

mexibeetle,
As far as the resolution of 1680x1050 I cannot answer you. I have a Power PC mini as well as an intel mini. The resolutions available change based on the display connected, but neither of mine offer that particular resolution (the 17" monitor I have does not go that high on the PPC mini via VGA and the intel mini is hooked up to a 40" LCD TV via HDMI...those resolutions are either 1600x900 or 1920x1080)
Neither my monitor nor my HDTV list that particular resolution (1680x1050) as being available, regardless of what they are connected to, so I cannot say whether or not the mini is capable of driving a screen at that resolution.
As to portrait mode, on both the older and newer minis in the display preference pane there is the option to rotate your image...90, 180 and 270 degrees. Mounting your monitor horizontal or vertical should not pose any problem as far as I can see.

How do you reinstall 64-bit Windows 7 in UEFI mode?

I have a PC with a single hard disk and, a while ago now, I installed 64-bit Windows 7 on it in UEFI mode.
The disk has two primary partitions: a C: partition which contains my Windows 7 system and other installed software such as Office, and a D: partition which contains only personal data.
(In other words, I don’t have a multi- or dual-boot system.)
I now wish to reinstall 64-bit Windows 7 into the same C: partition, again in UEFI mode.
There is a procedure for reinstalling Windows 7 documented on the following MS Web page:
http://windows.microsoft.com/en-us/windows/installing-reinstalling-windows#1TC=windows-7
in the section entitled “Using the Custom installation option without formatting the hard disk”.
The following YouTube video demonstrates this procedure:
http://www.youtube.com/watch?v=fr_s29MWOA0
and it looks relatively straightforward.
Essentially, the re-installation starts by inserting the installation DVD into the optical disk drive and running setup.exe while still logged on to Windows 7 with an administrator user ID.
At the screen entitled “Where do you want to install Windows?”, both the System Reserved partition (the example in the video is a legacy BIOS installation) and the C: primary partition are visible.
On that screen, you simply select the C: primary partition and click
Next, and Windows 7 is effectively reinstalled over Windows 7.
Any personal data in the C: partition is preserved in a folder called Windows.old.
The big question is, does this procedure work for a UEFI installation?
The documentation does not state that it works only for a legacy BIOS installation.
If I were to follow the procedure, when I reach the screen entitled “Where do you want to install Windows?”, I would expect to see the EFI System Partition (ESP), the Microsoft Reserved Partition (MSR), my C: primary partition and my D: primary partition.
Can I simply select the C: primary partition and click Next to start the (re-)installation?
It appears that nowhere in the procedure do you specify what mode of installation (legacy BIOS or UEFI) is required.
Does the installation setup simply use the same mode as that of the existing installation?
Does anyone have any experience of reinstalling Windows 7 in UEFI mode, using this procedure or any other method?

Hi,
It depends. Do you have Windows 7 DVD? Does your computer have a Boot from EFI Drive option?
Windows 7 DVD can boot in either BIOS mode or UEFI mode. Different UEFI firmware implementations support different methods for handling the installation operation. The processes for booting the computer into UEFI mode for the Windows product DVD are
the same. If you can find a boot from EFI Drive option, please perform the suggestions as i referred to.
If you cannot find any boot option, perform the steps below:
Use Device Manager's Firmware option and select Boot from EFI Internal Shell.
Use the EFI internal shell, as follows:
Start the EFI internal shell from the EFI boot menu and select the drive with the Windows product DVD. The following example assumes that the drive is Fs0:
Shell> Fs0:
Start the EFI boot application. For example, on an x64 system, run the following command:
fs0:> \EFI\BOOT\BOOTX64.EFI
After the application starts, you may be immediately prompted to press a key to boot from the drive to continue. Press a key to continue booting from the installation media.

Prepare an usb thumb drive, to boot windows 7 or 8 in UEFI mode

Purpose of this post:
Prepare an usb thumb drive, to boot windows 7 in UEFI mode and install the system in pure UEFI mode.
Why am I writing this:
I had a hard time finding out how to make a custom installation of windows 7 in pure UEFI mode, and avoid using the factory restore disks. After hours of research, experiments etc I finally got the point and found a solution. And I'm happy to share my research with you. I hope this will be of help. If something is not clear, or more information is needed, I will be glad to explain things further.
History:
As most of you already know, BIOS was developed for PC in early eighties and has remained unchanged in recent years. But, since 2000, Intel started working on a new firmware interface, called Extensible Firmware Interface, abbreviated EFI. And since 2005 United EFI Forum has been handling the responsibility for development, management and promotion of UEFI specifications. Bigger companies like Intel, AMD, Microsoft and Dell have already started to bring out their products in accordance to UEFI standards which has more stable, secure and easier to use interface.
How does UEFI works (in a nutshell):
Once you power on the UEFI based PC, the Pre-EFI is executed which initializes only the CPU, memory and the chipset. This followed by Driver Execution Environment (DEX) where other hardware is initialized.
Advantages of UEFI:
    It can integrate various drivers this will not require to load during booting so saves time.
   PC can connect to network without OS.
   Also integrated drivers allow rendering GUI based control panel which out dates the old school bluish BIOS screen.
   Not all the installed hard drives are scanned as boot drive is set during the installation of OS in UFFI.
   Applications like anti-virus and diagnostic tools can be stored on virtually any non-volatile storage devices attached to a PC.
For a system to boot and install in UEFI the partition table of the HDD should be GPT (GUID Partition Table), not the old school MBR (master boot record). GPT has many advantages, can have virtually an unlimited number of partitions (windows will allow only 128) and impressively big partitions.
Since UEFI has a lot of advantages why not having a system install and boot in UEFI mode? AFAIK new Lenovo notebooks/netbooks are UEFI capable and OS’s are already installed in pure UEFI mode.
So, let’s go now to the point. Do you want to have more control over your HDD? Let say, you have a 320GB HDD and you have divided it in two partitions, one of 50GB, for your Windows 7, and the remaining for your data. If something goes wrong and you need to restore your system to factory default, with the recovery disks, it will wipe your partition scheme, set the system to default and this way your data will be lost.
You may want to make a “vanilla” installation of windows from a USB thumb drive and avoid using factory recovery disks. Now here things get complicated. A standard preparation of the USB with Microsoft’s software (Windows 7 USB/DVD Download Tool), or other tools, will give you a bios installation, not a UEFI one. So for the system to boot, you will need to change some settings in bios, and changing it from UEFI to legacy bios. The installation will prepare the HDD in MBR partition table, and you will lose all the advantages of UEFI, described above.
Now this can be avoided, by properly preparing an USB to boot and install in UEFI mode. Here are the steps:
Step by step tutorial:
1.   In a windows computer, download a legal copy (although trial) of the windows 7 os. You can do this from here: http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/
Be sure to download the same version that came preinstalled in your computer. For example, if you have a Lenovo x120e, with a Windows 7 professional, 64bit, download an iso image of the Windows 7 professional 64bit.
2.   Once downloaded burn the iso to a USB thumb (at least 4GB) using Windows 7 USB/DVD Download Tool.
3.   After preparing this, create a folder on your computer, name it whatever (i.e. W7pro64bit). Go to the root of your USB
and select all the files and folders there (9 in total) copy, and paste to your folder you created, W7pro64bit.
4.   Using windows format the usb again in FAT32. Windows 7 USB/DVD Download tool, formats it in NTFS. We need a FAT32 formatted disk to achieve our goal. Formating again the USB in FAT32 will not touch the MBR of the USB thumbdrive. And after copying back the files (see step 6) the USB will still be bootable. (nice, and simple, isn't it?)
5.   Now go to the folder W7pro64bit and do the following:
a.   Browse to W7pro64bit\sources\ and open install.wim file. It’s a big file, and can be opened as an archive with 7zip (free software). Do not extract it, do not modify it, just browse the file with 7zip. Just to be sure you do not mess with that file, you can copy it somewhere else in your computer, and than procede.
b.   Browse this file (install.wim) to \1\Windows\Boot\EFI\ and locate the file bootmgfw.efi. Do not move, delete it, but just drag that file to the desktop. (if you have copied the file install.wim to another place in your computer, than you are safely do whatever you want with that file ) Close the 7zip program to release the install.wim file.
c.   Rename the file you just copied to the desktop from bootmgfw.efi to bootx64.efi.
d.   Now go back to w7pro64bit folder and browse \efi\Microsoft. Form there copy the folder boot and paste it one level up, on the folder: \efi. It will look like this: \efi\boot.
e.   Now copy the file you saved on your desktop and renamed (bootx64.efi) to \efi\boot (inside the boot folder you copied on step 5d
6.   Now go to the root of the folder W7pro64bit and select all folders and files (9 in total) copy, and paste all those files back to your USB thumb drive. (see step 4 for more info)
7.   Go to the computer that you are going to reinstall, and before restarting it, use the program ABR (activation backup and restore) to backup the license of your windows os. (use google to find ABR). Advanced Tokens Manager (ATM ) is great too. This link may be of help: Backup and restore W7 activation. After the program finishes its magic, it will create a few files inside the folder where the program itself reside. Copy these files to a new folder in your usb. Rename it to ABR so you will quickly find it later. (if you decide to use ATM, the procedure may be a little different. But you are smart enough to figure out how to use it)
8.   Backup to an external storage all your data before continuing.(reminder: are you sure you saved the license as explained in step 7, to a safe place? To a external drive, to another computer? If you are sure, than go on with step 9)
9.   Now restart your laptop, and enter your bios settings. Go to the boot settings, and set the computer to boot in UEFI only. Not both, not UEFI first, or legacy, BUT UEFI only. Save and restart.
10.   Press f12 (or the corresponding key for your machine) to choose the boot device and chose to start from the USB thumb drive with your windows 7 pro 64 bit.
11.   If everything is done correctly, your computer will boot from the USB.
12.   Follow the wizard and choose a custom install, not upgrade. At the disk partition window delete all the partition you see there until you have only one unallocated space.
13.   Select it, and click next to install windows, without making partition in this point. The installer will create a GPT partition table not a MBR since the USB booted in UEFI mode.
14.   Immediately after the first restart remove your USB thumb, and the installation will continue from the HDD. Wait until installation finishes.
15.   When you will be finally on your desktop, on the installed OS plug your USB go to the ABR folder and click on restore.exe. It will restore your license and your copy of windows will be activated.
16.   Now you can go in computer management/disk management and shrink the HDD to create your partitioning scheme. Make sure to leave enough space to your windows os. (30gb or more for extra programs you will install at your choice)
17.      Download from lenovo.com thinkvantage system update and update your system. Windows update too can install all the necessary drivers, if you need only basic drivers support.
Note: if tvsu will fail to work, see this:
http://forums.lenovo.com/t5/ThinkVantage-Technologies/ThinkVantage-System-Update-Servers-down-the-wh...
It may look a looong tutorial, but once you do this for the first time, it will look a piece of cake.
Final words:
From now on, you can install windows 7 in UEFI mode with your special USB without changing your partition scheme anymore. If you have a data partition beside your os partition (see the example above), when you reinstall the system using your USB thumb drive, at the disk partition window chose the partition where windows is installed, delete it, and reinstall windows to the unformatted area. Your partition with your data will be intact and the installation will automatically mount your data partition to the system. And, all the scope of this procedure, you will always have a pure UEFI installation of the system, with all its benefits.
Have fun!

Thank you, as I noted here, your post was the key to my getting a Windows 8 SecureBooting setup on a W530.
In the case of Windows 8, I needed to copy the files away, reformat my USB key as FAT32 and copy the files back, and viola I was able to boot from my USB install media with the BIOS set to only boot UEFI. From there, there rest was easy (for Windows 8, the copying and renaming is not necessary, the key is having a FAT32 partition on the USB media, rather than an NTFS one; the EFI files are already in the right location).
Thank you again good sir.
You are welcome... and I'm happy that the change of the file system helps with windows 8 too. Thanks for confirming that.

Why can I no longer watch music videos in full screen mode via a playlist in the music app since upgrading to ios7?

Since upgrading to ios7 my iPhone 4S no longer allows me to watch music videos in full screen mode when I select the clips via a playlist from the music app.
It's now more necessary than before to use the music app rather than the video app to select music videos to play. That's because the video app doesn't list music videos by artist any more. And also because the fast forward and rewind buttons on headphones remote no longer work on videos.
How do I watch full screen videos when rotating my iphone now shows my music library rather than showing the video itself?

I do not think it is a problem to play videos in the full screen mode using the video app. It should work just fine, it does work ok for me on iphone 5. The original question was to play music videos in the music app. Music videos and videos are two different things - I am not sure why but they are.
The problem here is that the music app supports lists and the video app does not. I just looked at the ios7 video app and while my few test videos are shown in it, the lists they were in (in iTunes) are nowhere to be found. There is no lists in the video app - period - which is as it was before.
The video app plays videos and music videos in the full screen mode no problem but if you have a few hundreds or more of such videos you will have hard time finding the one you want to play. There is simply no way to categorize or group videos. The old good folders/directories are, I guess, too simple for Apple. It is just too bad that for years on end the world's leader in S/W development did not offer anything to categorize videos.
You have lists, albums, etc., for music, you have albums for pictures but you have absolutely nothing for videos. And this is and has been the Apple's state-of-the art solution for this problem - simply insist that the problem does not exist. Actually it is getting worse. Not only there is nothing to categorize or group videos but now the only way it could be done (by marking videos as music videos and using the music app) results in a mini playback area.
Soon this OS will be able to cook dinner for your but grouping videos... no way.
What is happening here???

T440s & Windows 7 in UEFI mode

Hi,
I try to install Windows 7 on my T440s. However, I fail booting the USB stick with error code 0xc000000d ("An error occurred while attempting to read the boot configuration data"). I created the USB stick as described in the Forum here (http://forums.lenovo.com/t5/Windows-7-Knowledge-Base/Prepare-an-usb-thumb-drive-to-boot-windows-7-in...). Also, the USB-Stick boots fine in UEFI mode on my old (HP) Laptop. Also I can boot on CSM-Mode Compatibility Support Module. I tried several other how-tos and what else Google answered search fo that error code (e.g. disabling USB3, disable nearly everything the UEFI BIOS could disable etc...). It really seems to be an issue in conjunction with that UEFI implementation...
I'm using latest UEFI BIOS (GJET64WW, 2.14).
Anyone successfully installed Windows 7 on that model? Any help would be appriciated.
Best regards,
falstaff

Hi,
What do you mean by Also I can boot on CSM-Mode Compatibility Support Module ?
Windows 7 won't run in UEFI mode without CSM enabled. IIRC it may boot but won't run.
I don't have a T440s to test with, but here's how I make and boot a Win 7 UEFI installer: format a flash drive as a single partition - FAT32. Use an (un)archiving tool like 7zip in Windows to extract the contents of a Win 7 SP1 installer ISO to a flash drive. (or just copy a DVD to flash).
Boot it and install. IIRC the file manipulation required to create a bootable flash drive applied to pre-SP1 Win 7.

Booting in UEFI mode

Hello,
I have a Z77A-G45 mainboard which supports UEFI. I am trying to install Windows 7 (64 bit) on a GPT hard drive which already has Linux Mint 13 (equivalent to Ubuntu 12.04 LTS) installed. The disk is 1TB big and I have reserved 250 GB of unallocated space for Windows at the beginning of the disk. The disk was partitioned using Gparted (or the Linux Mint partition editor which is also based in libparted I think).
The problem is that the Windows DVD only boots in BIOS mode, so it's not letting me install it on a GPT hard drive. As I have read I must boot the DVD in UEFI mode to be able to install Windows the way I want. The problem is that in the boot options I don't have one for booting in UEFI mode (the only option I get is tagged 'CD/DVD:ATAPI iHAS122 C'). I have read that I can boot into the UEFI shell, browse the DVD and start the installation program from a UEFI boot file (*.efi). When I try to do that most of the tutorials tell me to point my prompt to fs0: but I only see blk'n' (n is the number of the device) block devices. blk5 is the DVD. I mount it using the command 'mount' and the prompt tells me it boots successfully. Then I point the prompt to 'blk5:' and it works, but when I try 'cd' or 'ls' I get the error "ls/dir: Cannot open current directory - Not Found".
I am certain my motherboard supports UEFI and I am quite sure it's enabled because I get the graphical BIOS. I didn't have any problems formatting the disk as GPT, and the Windows installer (in BIOS mode) recognises all the partitions correctly but it won't let me install the OS complaining about the GPT hard drive.
What can I do? Is there a middle step I am skipping? As much as I read around everyone with this problem gets to browse the DVD in the UEFI shell but I am stuck there.
Thank you very much in advance.

I copied all of the files from the dvd to a usb 3.0 stick and installed from the in UEFI mode. (Just select the UEFI: HP usb stick or whatever)
Are you sure you don't see UEFI: DVD Burner in the boot list?

The Graphics Output Protocol (GOP) is enabled by UEFI driver to support graphic console output in the pre-OS phase.
The ultimate goal of GOP is to replace legacy VGA BIOS and eliminate VGA HW functionality.

Windows 8 Pro Final (9200) BitLocker in UEFI mode not working, Element not found

Hi,
with the latest bios (either 1.37a (for Windows 8 Beta Driver test (June 2012) or 1.39 (Current) of the W520 and final release of Windows 8 Pro (Build 9200) BitLocker comes up with "Element not found" when trying to activate for the system drive in UEFI only mode.
In a new legacy only mode installation BitLocker works fine.
In both cases all devices in device manager are recognized. TPM 1.2 is active and working with e.g. the client security solution and fingerprint software.
I thought the UEFI / BitLocker issues have already been solved?!
Is there still an issue with the UEFI only mode of the W520?
Any thoughts or a bios update within sight?
Thx in advance,
nasenbaer
Solved!
Go to Solution.

Haven't heard of this issue with Win8. The issue with Win7/UEFI/bitlocker from last year is definitely solved.
Does this link help?
http://social.technet.microsoft.com/wiki/contents/articles/11518.cannot-turn-on-or-resume-bitlocker-...
EDIT: I tried this just now with Win8 Pro on T420 (same BIOS code base as W520) in UEFI mode. And bitlocker works fine. So I'm sure what problem is happening on your W520.

This is my thought, too. The "memory map has changed" message sounds like the firmware is messing with the way memory is laid out in the middle of the boot process. A firmware update, if available, is likely to be the best way to deal with this problem. If not, trying Fedora's patched GRUB Legacy and GRUB 2 are also worth doing; it's conceivable that one of them includes a workaround for the problem.
2. In your first posting you mention Windows 8 on this machine. Is W8 starting in uefi mode?
This is important, but if the disk uses GPT partitioning, then Windows is starting in EFI mode.
3. If W8 is starting in uefi mode, are you sure that secure boot is disabled?
It is; if it weren't, neither rEFInd nor ELILO could start -- or even if they were configured to start in Secure Boot mode, ELILO doesn't launch its kernels in a way that respects Secure Boot, so the ELILO failure can't be caused by Secure Boot. Also, when launched with Secure Boot active, rEFInd returns a clear error message about a security violation and then returns to its main menu; it doesn't hang the computer.
One possible workaround occurs to me if all else fails: Have rEFInd launch a BIOS version of GRUB. The setup procedure, in outline, is as follows:
Create a BIOS Boot Partition on the disk.
Install the BIOS version of GRUB 2.
Configure rEFInd to include a scan for BIOS-mode boot loaders by uncommenting the "scanfor" line in refind.conf and adding "hdbios" to it.
Thereafter, you'll see a new "generic" icon, which should launch GRUB, which should launch Linux in BIOS mode, even though Windows launches in EFI mode. This will work on most modern UEFI-based computers with a single hard disk, but things get trickier with multiple disks and with some UEFI implementations that lack the necessary firmware features. If a future firmware update fixes the problem, or if a future kernel's EFI stub loader includes a workaround, the EFI-mode booting will become an option once again.

Yoga 11s - how to boot from USB in UEFI mode (tried everything)

I have been trying for days to install Windows 7 on my new Yoga 11s in dual boot configuration with 8.1, with no luck. Typical catch-22 problem -- can't boot from the install media in UEFI mode, and if booted in legacy mode, Windows won't install on GPT partition. I followed all the steps everywhere mentioned: disabled secure boot, set boot mode and order in every possible combination, etc. I followed these steps exactly to create a UEFI-bootable USB drive:http://forums.lenovo.com/t5/Windows-8-and-8-1-Knowledge-Base/Why-can-t-I-boot-from-a-USB-key-on-UEFI-ThinkPad-or-ThinkCentre/ta-p/1004621 I can boot easily from the USB in legacy mode, but in UEFI mode, when starting the machine, the USB is ignored. If I go into Windows 8.1 recovery and do an advanced start and choose EFI USB, the machine thinks for a moment and then says: "System doesn't have any USB boot option. Please select other boot option in Boot Manager Menu." Then I click OK and it offers only one option on the menu, Windows Boot Manager. I don't know if the lack of boot options is just a symptom of the USB not really being UEFI-bootable, or some other steps are needed to add boot options. I even tried adding an item within the windows boot manager, but that didn't work, because even if it could work in principle I don't know the right settings. Has anyone actually made this work? If so, what is the secret?

I had the same problem and a lot of frustration. I finally solved the problem by using a different USB key. I also had to go into boot options and select the USB key even though I had the USB key first in the boot order. Right now I am Re-imaging from my backup and pray for success. Although things may look brigth afterall I have to leave out some steam:The whole problem started with a screen error, which had to be repaired. So before sending it to repair I made an image backup, - just in case. I got an eight hour time window where I had to wait for a pickup of the computer,- very frustrating when you are having a job requiring traveling. After ten days the computer computer came back with a scrambled hard disk with at note saying that it was an software error, although it was no doubt an hardware error because it worked perfectly with an external monitor. I have not counted the number of hours this bad service has costs but it exceeds the value of the computer!
