About T400s' EFI/UEFI rom

I'm an software engineer and fond of Thinkpad. I'm using over 10 thinkpad laptops/keyboards/etc. currently. None can be better than Thinkpad in laptop.
I'm using T400s for over 2 years and it's great. I'm using an Ubuntu Natty now and It can boot from GRUB to Desktop in about 6.3 seconds. But the BIOS is too slow!
I saw a famous video from Phoenix, they used a magical version of BIOS(EFI/UEFI?) to boot to the Bootmgr in 1~2 seconds. And I tried really hard (searched and read over 100 threads/blog posts/sth.else) to find something released or even something about it, but I failed.
I really really wan't to try that fabulous thing, even unstable, even buggy, even ... So can the stuff of Lenovo to help me to do this? I wan't be a volunteer for testing and I won't leak it to public(I can sign Confidentiality agreement with Lenovo if needed).
Thanks,

Lenovo won't release such update for the T400s, if you need UEFI you would have to get the T420s.

T400 and UEFI

Hi everybody,
I just recently saw a video(http://www.youtube.com/watch?v=DLwaKb6pLrc&feature=player_embedded), and it's keeping me hopeful that someday my T400 will someday load the 10 second boot time.
I was wondering if you guys think it will come to the T400 or would Lenovo only ship out UEFI on their new products only?
Solved!
Go to Solution.

I am 99% sure it does not have a different hardware, just a different bios rom. But anyway, of course Lenovo prefers do marketing and try to sell this feature in the next model. Me and many users like me will not change the laptop just to save 3 seconds of boot time...
Maybe somebody has somewhere this rom ... but maybe this is not the forum to post it
PS: Some video stating that actually there is not much difference in the official thinkpad supporting uefi

Question about multiple CD/DVD-ROM drives..

One CD/DVD reader, one CD/DVR burner. I like having two, but there is only one CD power port (JCD1). Am I missing something?
Also, should I master/slave them and put them under IDE1 or separate the two between IDE1 and IDE2?
Thanks for the advice.

Booting hangs at loading vmlinuz-arch.efi (UEFI boot)

Hello,
I have just installed Arch Linux on my desktop machine (UEFI motherboard) which contains drives & partitions as follows:
1. /dev/sda (~ 250 GB) with
1: Win 7 64 bit
2: ntfs partition for data
3: ntfs partition for programs
2. /dev/sdb (1 TB) with
1: ntfs
2: fat32 / vfat as the uefi partition thingy
3: linux fs with swap, root and home
I have followed the Beginners' Guide dow nto the letter.
So I used rEFInd to set up the UEFI boot manager. However, it hangs at using the vmlinuz-arch.efi file/partition (?) on boot.
I have tried booting with a new efibootmgr entry as well, but it still hangs.
At this point, I'd like to know:
How can I get rid of all the rEFInd boot manager entries?
What precisely do I have to do to get it working? I could, of course, read around on here all day, but I somehow won't really learn anything as I can't deduct the right path of action for myself. If the machine weren't my productive system I'd definitely "play" around a lot more, that's for sure.
Any advice is greatly appreciated.

OK, i will post, maybe it can help you!
First you need to boot from the arch installation media in UEFI mode. Mount your system partitions and chroot into it.
If you only have refind and kernel files under /boot/efi/ you can delete all files (clearing the EFI partition).Then run
modprobe efivars
. If you want to remove any efi entry, you can do it with
efibootmgr -b <entry_number> -B
Ok I did that.
sed -i "s/root=PARTUUID=XXXXXXXX rootfstype=XXXX ro/root=UUID=$(blkid -s UUID -o value $(df -k /)) rootfstype=$(blkid -s TYPE -o value $(df -k /)) ro/" "/boot/refind_linux.conf"
You meant here for me as wlel to exchange the X's wit hthe corresponding keys, right? I mean I did it. Would not make sense to me to call the comman with lots of Xs.
The rest was quite easy, I paid a lot of attention and made sure I typed in everthing correctly.
I am now at a blank black screen and there is a white underscore flashing in the upper left corner.
edit Can't boot into Windows anymore. Can't repair the MBR / UEFI boot with the Windows 7 DVD either...
edit2 Did lots of googling and at least Win 7 works fine again.
No. All the code is for you to type exactly as it is. The only statements you need to replace are <drive_with_efi_partition> and <efi_partition_number> with your current setup. What the line you questioned does is to replace the lines with "root=PARTUUID=XXXXXXXX rootfstype=XXXX ro" using the linux "sed" command, in refind_linux.conf with "root=UUID=<autodetected_uuid_of_your_root_partiton> rootfstype=ext4 ro". That will only work with the original refind_linux.conf, so if you edited it, you need to rerun
cp -r /usr/lib/refind/config/refind_linux.conf /boot/
There are 3 main reasons that may caused you to boot into a black screen with nothing written on it.
1. By not writing the code as it is, and editing files by hand instead, you may have done something wrong;
2. Your computer is booting from the wrong uefi entry, intead of the one created earlier;
3. You need to have "nomodeset" in your kernel boot line.
When does the black screen apears? After selecting a refind entry from refind's menu? Right after the pc boots (refind menu does not appear)
Another thing. In order for you to have access to windows, you need to edit refind.conf windows corresponding entry and remove the disabled statement or it wont appear on refind menu

Major concerns about Arch + T420s (UEFI)

Hey folks,
I got a couple of weeks ago my new T420s. Before this I used LMDE for a couple of months already. I tried to install LMDE on that machine, but never suceeded. After installation, I couldnt boot the system, it was stuck at the bootscreen of EFI, where you can choose which device to boot.
Then after a lot of tires (with, without legacy mode etc), I installed 11.10 beta, which worked booted flawlessly. It detected and even created the UEFI partition automatically.
And yes, Iam currently using Ubuntu 11.10. But I have to admit, that Iam not really happy with it. Iam looking more for a slim and rolling distribution like Arch. I know, that you cant compare the installation process to Ubuntu. But I would like to ask, if somebody has any experience with the whole installation progress.
Iam not the advanced user of Linux. So the whole issue with UEFI, grub2 looks very unfamiliar and complicated to me.
Does somebody has some step by step instruction, how to setup the machine with the T420s and Arch?
I looked up your wikis. There I was told, that you have first to install everything, then to boot somehow with a live cd/usb, and then over "chroot" or so to install all the needed packages and so on. But it looks almost impossible, to do so.
Has anybody any experiences?

Welcome to the boards esc!
I have the exact same machine as you and I can testify it is totally possible to install arch and boot with UEFI. It doesn't exactly work out of the box, so you have to be willing to get your hands dirty. With the command line that is
Make you fully grasp the concept of UEFI, how it differs from BIOS, before you start, it is easy to get lost along the way. Knowing what it is your dealing with helps alot to assimilate all the different steps. Here are a couple of pointers to get you started.
This thread discusses issues with UEFI: https://bbs.archlinux.org/viewtopic.php?id=111327
Get the archboot installer (from the Annoucements forum thread, or the wiki page). This is what i found to boot UEFI "out of the box". This is the first thing I did wrong multiple times, the installer itself has to be booted with UEFI to be able to complete the grub-efi install at the end of the process. With Debian (and LMDE), i think you would have to make a custom installer with grub-efi and efi added to it. Ubuntu does this, but not Debian, if I am correct.
To create an archboot USB read this: https://gitorious.org/tianocore_uefi_du … I_boot_USB
You can simply put archboot on it and not the other OS, it will still work.
Afterwards, this is your bible: https://wiki.archlinux.org/index.php/GRUB2#UEFI_systems
For full explanation of the efi configuration process. Little precision there, at the end, I copied the generated grub.cfg from /boot/grub to /boot/efi/efi/grub because that is the base path for grub-efi.
I hope this helps, let us know how it goes.

Question about T400s fan

Hi, I have a question for T400s owners,
Have any of you noticed a "hiccup" in the t400s fan? I can hear the fan (its not a quiet as some people say it is) and it clicks or hiccups kind of in a rhythmic pace every few seconds. I'm wondering if the fan is going bad

essaimel wrote:
Hello Samtoossi,
I have the exact same phenomenon on my brand new T400s (2808/D9G). It sound like there is some sort of strange mechanism to "respin up" the fan every few seconds : the fan speed is not constant at any time in fact, it spins a little down, then there is a little boost, and again and again.
I'm not sure this is an issue, even if I wondered at first... And now knowing I'm not alone...
Did you contact Lenovo for that ?
Thanls
No, I just use TPFanControl to keep the fan off most of the time. I'll wait until something major happens and then include this issue into the mix when I call lenovo. Im kind of hesitant to get anything in this laptop replaced right now. If its the fan that needs to replaced, its not a big deal, but If its a motherboard issue there is no way in I'm going to replace it because there are many reports by other owners of annoying processor whine, unresolved random shutdowns, and melted speakers. I'm pretty happy with the current state of my laptop, thanks to TPFanControl
FYI, this looks very similar to the infamous "pulsing fan" problem that affected many of the earlier IBM Thinkpads. Its due to ACPI polling the fan RPM every few seconds (every 6 sec for my T400s). IBM eventually released a BIOS update which fixed the problem. If you run TPFanControl, you will see that the pulsing is only noticeable under fan speed 2 which constantly changes speed. Fan speeds 1, 3,4,5,6,7 don't have this problem (speed 3 kind of has it, but its no where as annoying). It could be that this is a common problem, but most people just don't hear it because of ambient noise or they're just not bothered by it. Hopefully, a BIOS update in the future fixes this problem.
If you decide to call Lenovo and have the fan replaced, let me know how it works out

Is there any technical details about T400 builtin camera available for public?

Hi
Can someone please let me know what is the model or brand of T400 integrated webcamera.
I just want to search and see whether it is supported by linuc or not.
Thanks.

In my T400, the webcam is from Sonix. The driver is for the models SN9C211 and SN9C213. So likely, one of these models is in the notebook.
The website is: http://www.sonix.com.tw/. Though, there are no Linux drivers listed in their support section.

About T400s fan

I reinstalled Windows 7 using another new copy of win 7 instead of the one preinstalled by lenovo which was accidently deleted by me.There is just one problem: the fan will continuously running at high rotation speed and generate large fan rotating noise once it reaches that speed and, even I do not run CPU consuming applications. It seems to be constantly running. I guess I did not install some necessary drivers. Does anybody know how to deal with this problem?

I'm having the same problem with my T410s. I did not reinstall Win7, factory install.
But whenever plugged into AC, my fan seems to be running at a pretty loud speed considering I am not putting any load of the CPU. It could be idle for 10 mintues and the fan will still be running at probobly 75% of its capacity. The second I unplug from AC, then fan becomes nearly silent.
I've tinkered with many possible combinations in the Lenovo Power Manager under advanced. Under 'Optimize Fan Control" I set it to 'Reduce Noise Dynamically', that causes the fan to become nearly silent for about 5 seconds and then kick back up for 5 seconds, and then go back to near silence for 5 seconds continually (Very annoying).
Any suggestions? Even when I set options in the Lenovo power manager under advanced that shows that the fan should be running quiet (as judging from the low amount of ticks under the fan sound level area) the fan keeps going at the same constant speed- no change.

How can i install 8 gb ram on a mac mini early 2009 when it says i dont need the EFI firmware 2.1?i can only install 4 gb but the side of OWC says i can install 8 gb? what to do?

i have a mac mini early 2009 and i want to install 8 gb ram but it doesn,t work.
it says on the OWC site that i have to install the EFI firmware 2.1 update but it won,t let me,it says(the mac mini)that i don,t need this update.
my kernel is 32bit but my EFI is 64 bit,how can i install 64 bit so i can use the 8GB cause with 32 bit i can,t use more than 4gb ram

Check your computer's EFI Boot ROM version;
1. From the Apple () menu, choose About This Mac
2. Click More Info Under Contents
3. Select Hardware
If your Mac mini's Boot ROM version is the following or more recent, then you do not need the update to use 8 GB of RAM;
Boot ROM Version: MM31.0081.B06

EFI Update Question

Hey all.
I just have a question about the EFI update that i have been promted to install via the update function on my new MBP 2011.
But then when i read witch models that are affected, then my model is not amoung the affected models, so why do i need to install this update...?
Therefor my question is this...! Is there something "sinister" about the hardware, that i dont know about in my MBP 2011 edition, since this update is primarily for older MacBooks. So is it an "old" MacBook in disguise.....or just something everybody has to install...?

The EFI updates are designed to install Apple monitoring software so they can read your hard drive, your browser and record any ripped MP3 files or other copyrighted media you have.
This is the exact intention of why EFI was created by Intel at the behest of the media industry. The UEFI forum is run by the MIAA and RIAA lawyers, the same who now run the US Justice Department
http://www.wired.com/threatlevel/2009/04/obama-taps-fift/
http://www.uefi.org/about/
You have no access to EFI, it does exactly what it pleases, your OS X and programs you install have no control over it or even can tell what it's doing.
If EFI allows you to do something, it's because it is, it has the power to stop you as it sits between your OS and hardware.
Every wonder why you can't boot off certain OS X install disks? It's because of EFI.
Apple sent out a firmware update and disallowed any booting off 10.5 disks, try it!
Not only that, Apple has scrambled the airport wifi signals so you can't use sniffing software on another Mac to determine if EFI is making outbound connections.
Also Apple has turned off the Airports blinking light, or if you like the blinking, it blinks all the time without any regard to if there is a transmission going over it or not.
To add further insult, new wired keyboard from Apple require software installed, firmware in the keyboard can record your keystrokes.
The pieces to a fully secure, fully monitored, computing system is slowly being lowered into place.
In fact the iSight camera can be turned on remotely without the green light appearing for covert surveillance.
Apple has hired NSA expert David Rice to lead it's computer security team, you KNOW the NSA has backdoors

Do you really think the Mac has been ignored?
It just works better in EFI that's all.

UEFI information...

I made a recent post about how to disable the onboard RAID300 on my RD430. And there was an answer. But after 20 or more frustrating hours later, two things are very apparent:
1) There is no "bios" documentation.
2) Lenovo's implementation of UEFI and the "Bios setup" need explaining; specifically, the interaction between various options which can cause my GPT UEFI option to not work anymore.
Much like this thread, I want all UEFI and no legacy. Or at least something that clearly explains why I can't boot my RD430 from any of the boot options, legacy or efi when things go wrong, like changing one setting in bios to enable the disabling of the scu.
What I have found with my RD430 is that if I do anything to disturb the bios or make any hardware changes which disrupt the ordering of the disks, my server won't boot. Combine that with my lack of understanding of the interaction of UEFI and the rest of the system and I'm questioning my investment in a proper server.
My Google-fu did help me stumble upon this amazing Lenovo document, which is the singularly most helpful explanation of UEFI I have found on the internet. Why? Because it provides usage examples.
To those who read and might know:
I read about a USB UEFI diagnostics utility; can it fix the boot variables in NVRAM when I do something that makes my RD430 not boot?
I had to reinstall the OS after I took the advice on disabling the patsburg scu to turn of the raid 300. Now I moved the raid card to the other free PCIe 3.0 slot and am trying to use a live CD to re-write the nvram variables. I documented the process, so in the unlikely event it is a successful recovery, I can post the details. My full expectation is the need to reinstall the OS again...
Thanks,
Chris

I found a great way to actually SEE what is in the UEFI boot table is to boot a linux live CD in UEFI: mode and then modprobe efivars then efibootmgr -v to see the results. This post helped me recover my lost OS.
It would be fantastic if Lenovo (or someone) could come up with a bootx64.efi that enables the user to easily map the boot table entries in the UEFI nvram! The program could scan the drives and partitions for valid EFI/xxxx/ffffx64.efi entries, show them in a table, and let the user alter them. It should show something of a PCI drive layout, which partition, and the files' paths. Labels would be nice, but I'm not going to be greedy.
The bios' uefi boot menu has bugs and it definitely does not scan entries accuracy.
