BIOS bug - booting fault ?

I recently discovered my Corsair TWINX 3200XL (2x512MB) is capable of DDR520 @ 2.5-3-3-8 1T, 2.75 or 2.8v and wanted to test 10x260 for a while, but I have a problem with PC not booting.
Memtest86, Prime95 blend 6hrs, SuperPI few tests, all OK right after OC'ing in Win XP, I'm 99,9% sure rig is rock stable, but the problem is that OC is short-lived...I have to clear CMOS coz PC won't reboot.
Also, noticed in BIOS that CPU Frequency is miscalculated, maybe this has something to do with the booting problem ? CPU FSB higher than 255, and the freq shows 0MHz or above...
10 x 255 = 2550MHz
10 x 256 = 0 MHz
10 x 260 = 40 MHz
BIOS CPU FREQ FORMULA = Multi x (FSB MOD 256)
(not double-checked these values, just what I think I remember from OC'ing)
Seen ppl with many different modded BIOSes, any of these could solve my problems ?
PSU is not very good, at (1.4 + 8,33%) 1.5166v it fluctuates 1.50-1.54 - or - if I set vcore fixed, it won't raise much at all..think 1.42v (at fixed 1.52v setting)..but when adding % to vcore from BIOS I get correct values.
/// EDIT, installed OCCT and posting results
No C'n'Q enabled, AMD64 driver not showing in "Remove Applications"....but I see vcore is "adjusted" to stress..

Assuming your sig is correct, then why not try Sideeffects 1.C final bios - even got improved vcore stability ( don´t know how that is done with a biosupdate) :

or Syar´s EasyBios with good default values :

and see if your coldboot problems and frequency recognition gets better........

Lenovo Thinkpad T520 doesn't boot with GPT slices on FreeBSD 9-BETA3 - BIOS bug?

Hi!
I've bought a brand new Lenovo Thinkpad T520 laptop and decided to install FreeBSD 9 Beta 3 following this guide.
But when I rebooted the system, it simply doesn't boot (turns out to the BIOS boot menu).
It's even doesn't boot with default FreeBSD 9 UFS-on-GPT installation scheme through bsdInstaller
Changing BIOS (latest, 1.31) settings BIOS Startup->UEFI/Legacy Boot from "Both" to "Legacy only" has no effect. As FreeBSD AFAIK doesn't support UEFI boot, legacy boot should work picking up and starting pmbr (protected MBR record), but it doesn't.
However, FreeBSD 9 UFS-on-MBR installation (with mbr boot record and FreeBSD slice in MBR partition instead of GPT) works fine.
It seems to me that UEFI/Legacy Boot "Legacy" setting actually has no effect if 0xEE type Primary partition entry is present on disk.
First of all, has anyone installed Linux or FreeBSD with GPT partitioning scheme on latest Thinkpads?
And the second one, as I've saw similar problem on FreeBSD forum thread about T420s laptop I believe that this may be a bug in the BIOS. How can I fill the bugreport or send an e-mail to support or developers, as, obvious, phone support can consult only about Windows OS.

I've got a suspicion that the Thinkpad bios/efi is not simply executing the first stage bootloader, but looking around on the GPT disk and then crapping its pants when it doesn't find Windows.
Right now I have a MBR-formatted harddisk in the ultrabay with the bootloader in the MBR. Once I get the bootloader off the MBR disk, I can easily continue to boot from my GPT-formatted SSD.
Yes, it seems that it's a BIOS bug at least on T520, T420s and W520 laptops. Even in "Legacy" mode first stage bootloader doesn't execute if partition type is 0xEE (GPT).
Hope Lenovo developers will fix it. They fixed something on BIOS 1.31

- Fixed an issue where the computer might not be booted from bootloader program.
but it doesn't work for now. Pity.

I'd heard about a bios bug!

Hi guys,
my system running not allways stable!I got some bluescreens of the art "STOP COMMAND"!
Exactly this three ones:
IRQL_NOT_LESS_OR_EQUAL
PAGE_FAULT_IN_NONPAGED_AREA and
BAD_CALL_POOLER
HERE are some information about it,but sorry,it's in german!
I think that the faults causes maybe in that two ways!
Once is a Memory error,because I become sometimes error Popups,that adresses can't written or read!
I use one TwinMos Modul of PC3200,512 Mb!
At the moment I test it in slot 3 and it seems to be more stable as in slot 1!The time settings seems to be not so important,I can use either 2.5-3-3-6,or 2-3-3-6!Normal is(I'm not sure 2.5-3-3-8)!
But more important I think is,that the motherboard monitor shows me a core voltage of under 1.5V~1.48v!!!That is also the reason I mean,that I can't overclock my system over 205 MHz frontsidebus stable!In 3D Mark 3 I get instantly by the first test Wings of Fury a totaly blue screen(not the error bluescreen!Much darker and without any message!)
So I'd heard about a bug in the AMI bios,that you can't store a new core voltage!Either increase,nor decrease!My settings are on 1.55 Volt!Isn#t that the right voltage for the prozessor and if,why it isn't there a possibility to increase the core voltage for overclocking!But that is a must for a good result!I'm a little bit confused about that!The other possibility is,that my PSU is not strong enough!What for a Voltage is important for the CPU Core?I mean the 3.3V,or?My customer had said that he test the PSU and it's stable!It shall be have 32A,normaly it is enough to hold the voltage correct,but I knew that in china the electric is another as in germany!!!
Another problem is that I have change my drive from the VIA controller to the promise,because I would first test the speed and if this controller is able to read the correct monitoring data(Firmware,temperature,UDMA mode...)!The VIA doesn't do that but the promise can!And I use now together my old seagate drive on it.
Because HDTunenow show me the correct UDMA mode,I'd seen that both drives are not running at their best settings!The samsung run at UDMA5,but can run on 7 and the seagate run on UDMA2,but can do it on 5!So I would change it,but I have no idea where I can do that!In the hardware manager it isn't a possibility,neither on IDE(there is only the VIA),nor at the SCSI devices!I cannot see any settings therefor at the promise controller!And if I change the settings in bios on RAID(for S-ATA) and go into the RAID Menue with Ctrl+f on bootup,I can see keys for changing values,but their shows no result!And I think if their would working I can't use it,because with the RAID setting the computer will not boot if you don't create an array!
Has anyone some ideas???
Thank you very much!

Thanx man!
How I write it in my system specifications,I'd try to change the slot and it seems to be better with the RAM in slot 3!
But,is it my not so good english or why you did not wrote anything about the bios bug I'd heard from!Is it true that it gives a bios version with this bug,that doesn't allow to store another core voltage?Because I think that is the problem!That my core voltage is only at 1.48V,wether I changed it to 1.55V,neither if I do that in bios,nor in bios on auto and do it with core center!
What is the "normal" processor voltage?1.5 V?And if,why it gives no possibility to increase it higher than 1.55V for overclocking?What for voltage amounts are important for the processor to run stable?Only +3.3V or also the +5V and +12V amounts?
But anyway, it seems to be that the +3400 version of the processor is coming at its end of power and isn't so good to be overclocked!Better I'd bought a +3200 one I think!
But my system is also good without overclocking if I take a look at my 3DMark and Aquamark results!!:worship:
And my system isn't so old,only 2 month,but the errors comes also in the fresh system at the first days!
Greetings from good old Germany!

Thinkpad S540 possible BIOS bug concerning WOL

I have had a Thinkpad S540 for a few months, and have it installed as dual boot Windows 8.1 and arch linux. After completely shutting the machine down from linux I found that the battery would be down to around 70% charge after three days unused, and decided to investigate this problem since it was not reasonable for a new battery to lose charge at anything like this rate.
By chance I came across a piece of information concerning the issue of disabling WOL (Wake on LAN) on the network interface, since I had seen one report that by default WOL is enabled and this requires power to be going to the network interface even when shut down in order to be able to respond to magic packets to start the machine up when it is shut down.
First I checked the BIOS WOL setting and found it was set to "AC only" by default. So I changed it to disabled. This machine has the latest available BIOS version 1.54.
However on investigating this after rebooting in linux I found that
# cat /sys/class/net/enp3s0/device/power/wakeup
enabled
# ethtool enp3s0 | grep Wake-on
Supports Wake-on: pumbg
Wake-on: g
So WOL was still enabled despite it being set to disabled in the BIOS!
I learned that I can make sure that in arch linux the WOL setting can be changed to set to disabled after bootup by using a udev rule:
# cat 70-disable_wol.rules
ACTION=="add", SUBSYSTEM=="net", KERNEL=="enp3s0", RUN+="/usr/bin/ethtool -s enp3s0 wol d"
Then rebooting the machine I checked the WOL setting and it really is disabled now:
# ethtool enp3s0 | grep Wake-on
Supports Wake-on: pumbg
Wake-on: d
# cat /sys/class/net/enp3s0/device/power/wakeup
disabled
So I then ensured that the battery was 100% charged and shut down the machine and left it two and a half days - rebooting this morning the battery was still at 100% charge and no longer discharges unnecessarily when the machine is switched off, so this is a clear indication of a bug in the BIOS for the WOL setting - it is still enabled despite the BIOS saying it is disabled!
How do I report this to Lenovo so that they can fix the BIOS and release a new one that is working?
I am aware of other users with different Thinkpads who seem to have the same problem, so this may be more widespread an issue than just on the S540.
It is also not just an issue with the battery running down when fully shut down but will likely also be a problem for a machine in suspend mode since the network interface may be consuming a watt or so of power when in suspend, which will again run the battery down at an unacceptable rate.
I cannot imagine any use case where it would be necessary to have WOL enabled on a laptop that is mostly going to be used mobile - so having the default setting to AC only enabled, and having a BIOS bug enabling it when it is explicitely disabled is a serious problem.

Anyone running windows in the same laptop can check the same issue of battery drain due to WOl being enabled by default - in the Device Manager under the network card, opening the settings menu for the ethernet wired card the default for Wake-on-LAN on my computer was set to enabled. This can be changed to disabled, and you may need to also disable the setting for Wake on Magic Packet. Also in the Power Management tab it is possible to uncheck the settings for "Allow this device to wake the computer" and "Only allow a magic packet to wake the computer"
In my laptop these were all set to enabled by default.

U110 BIOS bug?

Dear colleagues! Just got my new U110, seen Vista to work well and trying to install Debian Linux (Lenny) in it. When booting to the Linux system, I see in the very beginning this message:
PCI: BIOS Bug MCFG area at e0000000 is not E820-reserved.
PCI: Not using MMCONFIG
PCI: Cannot allocate reseource region 98 of bridge 000000:1c.2
Further, I have problem with starting X.org using xorg-xserver-video-intel . I am not sure if the problems are related, nor do I know if the first one is serious or not. Would appreciate any suggestions or solutions to either problem.

Hi Tommy,
Tried the acpi off switch. Didn't work. In fact I redid the install with the linux acpi=off. However no luck. I switched acpi to no in BIOS too, however, no luck with that either.
The reboot issue persists with ACPI: unable to locate RSDP showing up.
Will try the to look for the USB setting in BIOS as per your suggestion and get back to you.
Ta very much,

S10-3T BIOS bug?

We have purchased four Lenovo S10-3T (product code ********, greek version) and all four have the same problem:
Out of the box and on first boot, two BIOS issues appear:
ERROR 271Check Date and Time setting
WARNING 251 System CMOS checksum bad - Default configuration used
When you hit F2 to setup, a password is required - although no password has been set. A blank password doesn't work.
When you exit the setup (without entering the actual settings due to the password protection) , Windows first time setup continues with installation and creation of user account etc.
When I retry to enter BIOS Setup, the password prompt always appears.
Also have a look below at the screenshot.
Is it a BIOS bug which enables a supervisor password, or maybe a backup battery issue?

K7T Turbo2 - how do I tell BIOS to boot from USB?

I have an old K7T Turbo2 system, and I'm trying to install Windows 7 on it. I guess that's my first question - am I going to run into any nasty problems running W7 on this board, other than RAM limitations? I have a version of "Tiny7" (which installs from CD-ROM) installed already and it seems fine, but I'd rather run a fuller non-pirated OS, and that means installing from a DVD/iso. I don't have a DVD drive installed and it would be a bit of a pain to acquire one, so I'm hoping to boot from USB to winstall W7.
I have a PCI USB2.0 card installed in the system, which seems to work fine. I've set the BIOS to boot from USB-FDD (but I've also tried USB-CDROM and USB-ZIP). I have BIOS 3.6. I've tried booting from the PCI USB2.0 hub (will that ever work or does the BIOS not recognize it?) and from the regular USB1 port on the mobo (but my USB flash drive is USB2).
Is there something else I need to do in the BIOS to get this to work? Will it never work no matter what I do?
I read somewhere about a BIOS setting to "enable legacy USB support" but can't see anything like that in my BIOS settings.
Any suggestions? (thanks in advance)

If there is no option to boot from USB-HDD then it may never work.
Long shot I know, but what if you connect your USB drive, then power on your system, and press F11 when the logo/POST screen appears, does the drive show in the Boot Menu that appears?

Really? DVD drives are very common, and cheap as chips! You can pick up a brand new DVD writer, for the price of a (good) DVD movie.

Satellite U940-108 - How to configure BIOS to boot dual OS from SSD / HDD

How can i configure the BIOS to boot multi os ssd and HDD?
I want to boot from SSD one os and other os from HDD,
When i try to do it i have windows error?
Can you help me

Hi
I assume you want to install the OS (which one???) on the internal mSATA 32GB SSD?
This mSATA SSD is used for caching (hybrid boot) in order to boot Windows 8 faster.
I would recommend you to install the second OS on the HDD.
For that you should create new partition which could be used for OS installation.
Then boot from the Windows installation disk and install the 2nd OS on the new created partition.

Cannot enter BIOS or boot from LSI MegaRAID SAS 9271-8i

Hello,
I have a LSI MegaRAID SAS 9271-8i installed in a C220 M3 (in PCIe1). When I go to CIMC, I can see the adapter there and I can create RAID arrays. I can set the first logical drive to be the boot drive too without a problem. If I boot from ESXi installer it will see the disks and install to them.
The problem is, the server won’t boot from the disks, and I don’t see any problems for the card’s BIOS during boot. I have disabled the on-board RAID controller.
How do I get the server to boot from the RAID card?

Hi,
Glad to see the issue is resolved now (I never saw your post before) was it that the OptionROM for the PCIe card was not enabled or the boot order was not properly set?

N95 Maps - bug or fault on me???

I just got my N95 couple of days ago and I must say I just love it:-). I haven´t noticed any bugs or faults on the phone so far. It´s been working very nicely. But when I go to MAPS it sais: "Network usage disabled. You can enable it from application settings."
I have tried to change settings but I haven´t really found the right settings - I guess. I have been to applications but there isn´t anything to change that would fix my problem. Anyhow, I can start the Map- application although this sentence will pop up every time I will go there.
If someone could help me with this I would be really greatful.

Hi,
If you open maps, get past that message and goto options>settings>network change the option in Network to "when needed"
Beware though of data transfer though, as depending on what you do or if you have a map already in your phone if will attempt to download maps, voices etc
Data transfer through the network in most cases means £££, unless you choose wlan...
Hope this helpsMessage Edited by luckieb on 22-Apr-200703:16 PM

BIOS Changed Boot Order By Itself

I have a Pavilion H8-1360t. When I got it in March I installed a Samsung SSD. I copied the original Hard Drive to the SSD and made the SSD my boot drive. I also swapped the SATA ports becasue the HDD was on the high speed on. For the next 4 months I've been booting every morning and shutting down at night with no problems. The SSD boots quick and again, no problems. The SSD was my C drive and the original HDD was now my F. I only used it for Ghost backups of the C drive. I also Ghost to an external USB3 drive.
This morning when I booted I noticed that all my icons were missing as was all my data and all my programs I had installed. AFter some research I found, in the Computer display of my system, that my SSD was now the F drive and the original HDD was now my C drive. So I was booting using the original HDD that came with the system.
I tried to figure out how to tell the BIOS to boot from the SSD as it had been, but I cannot figure out which drive in the display list is it and besides that I want it to do that by default. I'd also like to know how or why the PC decided to reassign thedrive letters and boot from the HDD now.
HP refuses to help saying that since I have user installed devices they do not have the tools to help. They also cannot tell me how to get the Boot Order changed. But even if I could do that, and I've tried going into BIOS setup and Boot Priority, I cannot get it to boot using the SSD. HP suggested I go to some third party. But there's got to be a solution I can do. My last choice would be to copy the entire SSD to the HDD (the SSD id only 500GB and the HDD is a Terrabyte). I assume then that when it would boot from the HDD the data I copied over to it (using Ghost) would make it look then like the SSD did. My loss would be speed but at least I'd have critical data that I now cannot access.
I am really up the creek right now Any ideas?
Thanks

I took the PC to Fry's. They think there's a problem with the SSD. Even though I am able to see it and to move data off of it, there is some problem during boot that tells W7 and BIOS that is cannot boot and that is what is causing the system to then look for another boot drive. It then finds the hard drive, which came with the system and is connected, and is bootable, and thus it boots from that drive and also remaps the drive letters, effectively swapping the C and F between the SSD and HDD.
Now I am trying to move all my data to the HDD, install Office and other programs, and just boot to the HDD until I can get the SSD examined for problems and a new one, if necessary, put in.
PC's are such a joy.

T440s fn ctrl swap bios bug

Hi,
I think this was documented before, but I am now experiencing the fn ctrl swap bug when going to sleep.
I have swapped my fn and ctrl keys, and the setting never stays after resuming from deep sleep.
I have updated my bios to the latest version (2.19) but it has not fixed it.
Please advise. I do not want to turn off deep sleep.
Cheers
Solved!
Go to Solution.

Thank you for reporting this. Yes, I can confirm it is BIOS bug. We had this same issue on T430 generation and fixed it. But now it seems T440 generation also suffers from this same bug, needs fix. So I will report this to BIOS team. Sorry for this inconvenience.
