My DX58SO2 running BIOS version 0876 is currently locked into its current BIOS settings. And the current BIOS settings do not allow me to boot from anything. Most notably, it is locked into UEFI mode and into "load Setup at boot" or however it is called. I did choose these settings at one point, but cannot revert.
I can go into the BIOS setup and change what I want, but the board will boot up with exactly the same settings, that will not allow me to boot anything.
I tried all the obvious things:
- load BIOS defaults from the Save and Exit menu. Ignored like any other change
- switch the CMOS jumper from normal to clear
- remove the CMOS jumper and reboot
- press the BIOS Back button and reboot
- remove the battery for five minutes
- remove the battery for half an hour
- remove the battery for 8 hours
The board warns me that the CMOS battery is bad, and each time says the settings will be cleared. But every time the board comes back in the "press <ESC> for normal startup and <F2> for setup" mode. Every time UEFI mode is enabled. The best result was that the clock was set back to 2010.
How it got this far:
I was trying to get my Linux workstation to boot from UEFI. I did not succeed booting from either CD or SSD in UEFI mode, but I could boot from an EFI USB stick containing a Fedora 16 installation image. Shortly after that, I noticed the BIOS was stuck, and I could not get back into booting my BIOS-based Fedora 16 installation on my hard disk. I then managed to hack this USB stick into taking over the boot process of my Fedora 16 workstation. That worked. So I achieved my goal, beit with the help of an USB stick.
Had I rested at that point, nothing serious would have happened. But then I started using efibootmgr, a tool that should be able to make named boot entries into the UEFI nvram. That did not work and now I am locked out of everything. When I try to boot, I just get a zero "0" somewhere in the down right corner of the screen.
The UEFI nvram ought te be cleared in the same way as the BIOS settings, and none of these are possible right now.
Is my board bricked?
Update: I've left out the battery for a whole weekend. Still the BIOS settings are not cleared. Still they are stuck. I have no other explanation for that other than that this board must be storing its settings in flash memory rather than nvram.
I did manage to get my system booting again. I could undo the changes made by efibootmgr by booting from the SystemRescueCD on USB stick. I can now again boot my Linux installation on my harddrive by booting from an UEFI USB stick using grub.efi.
But I'm still locked out of booting from harddisk directly, and from booting from CD.
So, is there any other option to get control over the BIOS back, other than returning this board for warranty?
Since I can only boot from USB in my current settings, I tried to use iflash2.exe from a DOS bootable USB stick. iflash2.exe has a /f option to reset the BIOS settings to default. Unfortunately, it will only do that if there is also a BIOS upgrade to be performed. Since there is no newer version, I tried flashing the same BIOS. But iflash2 refuses that.
So I downgraded it to 0724. The downgrade was completed successfully, but the board is dead now.
The board responds to the on/off switch, and lights flicker, but there is no video and no signs of boot progress.
The LED stays at 00.
Pressing the BIOS Back button or setting the recovery jumper do not change anything.
I will have to return this board ...
just saw this thread. The same here:
[url=http://communities.intel.com/message/157656?tstart=0#157656]DN2800MT can't modify any BIOS setting anymore[/url]
even the simplest things (to erase everything in BIOS to some working default) does not work safely on todays computer hardware.
Instead developers focus on Graphical BIOS User Interfaces and other unnecessary crap^^
same drama here, of course after buying alle the stuff, including a 120Gig SSD for this crappy board.
After many many attempts and reboots and pushing the F2 button I managed to get in the BIOS but the BIOS forgets every change!!!!
I even flashed the bios on the "BIO-way" and restored and saved the new bios.
Result: windows crashes and tries to resore the computer to the previous working session......
A whole day burned because of this crappy atom board!!!!
My advise to Intel: go back to "Asus-school" and only do what you do best: making normal non-atom cpu's!!
I have the exact same issue on a DN2800MT board. Unable to change any values in the bios except the date and the time. The error exists in the latest bios (159) also. I've tried to disconnect the battery for about 3 hours but the settings remained, and still can't change any value. Does anybody have any solution?
Intel!!!? Do you have any comment on this?
I've followed your instructions. After pressing the F9 the BIOS loaded the default values. But after pressing the F10 and Y powered off disconnected from the power supply and restored the jumper to 1-2 and powered on the BIOS still shows the previous values not the default values. It seems the BIOS can't save the changed data.
