ASROCK BIOS prob

[visule]

hello,
I have the ASROCK 939-DUAL running windows XP sp2. I boot from SATA1 HD's set to RAID 0. Everything was working fine until I changed an IDE setting in the BIOS. (AMI BIOS P1.20). The only IDE device I have is a lite-on CD burner.
I changed the "on board IDE controller" to Primary ( was set to BOTH)
also changed the "Primary IDE Master" to CD/DVD (was set to Auto)
also changed the "Primary IDE slave" to Not Installed (was set to Auto)

upon boot, the system BIOS hangs up (stops processing) after the memory test as follows:

Auto detecting Pri master ..ATAPI CDROM
Auto detecting 5th master ..ATAPI CDROM
Pri master: Lite-on Combo SOHO 5235K LK02
Ultra DMA Mode 2

..And then it just stops. It doesn't matter if I press F2 or not.

The code on bottom left corner says 0078

When I press F2 to get back into the BIOS setup utility, it says "Entering Setup" but it doesn't give access.

I can't get back into the BIOS setup. Please advise.
Thank you for your help.

Unplug the computer from the wall open the case and remove the CMOS battery on the motherboard for about a minuite then reinsert the battery plug it back into the wall and start your computer. This will reset your bios configuration and allow you to enter bios.



Good LUck

Hi all,

I am having the exact same problem with my mobo its a Asrock K8Upgrade-VM800 can't seem to work out what it is. Also, My pc doesn't always boot the first time it doesnt seem to recognise the SATA drive in BIOS and sometimes it does generally on the second boot it does but not always from a cold boot. did clearing the bios work???

Virtually all motherboards have a CMOS/BIOS clear / reset jumper. That jumper is usually located next to or very close to the 3.3V Lithium battery. It is not necessary to remove the battery -- you can simply use the jumper to reset the BIOS following the reset instructions in your manual.

While removing the battery should also work there is a chance you may cause significant damage to the motherboard while removing the battery. Some battery holders used on motherboards are very flimsy and may break or fall off completely rendering the motherboard useless.

Well that is true that virtually all motherboards do come with the three pins bieng 1-2 is clear and 2-3 is hold data Asrock boards have the spot for it but half the time the pins are not there only the solder points. And that are damn near impossible to short and clear CMOS since the PCB has a protective coating on them. Do you feel comfortable picking at a motherboard trying to make a short? Would you feel comfortable telling Joe Schmoe to do this? Taking the battery out on those boards is a snap and produces 100% resulsts instead of possibly telling someone to jump pins that may not be there. I have seen over eight of these boards and only three of them actually had the pins to clear CMOS present.

Yes you are correct! 🙂

[code:1:131d8261f5]
if(!exist(CMOS_reset_pins()))
{
remove_PWR() && remove_lithium_battery() && sleep(30);
}
else
{
remove_PWR() && short_pins_2_3() && sleep(30) && restore_jumper_to_pins_1_2;
}

ASRock must be getting really stingy if they cannot afford to include a 1x3 pin header on their boards... geez


From Tyan Motherboard Manual:

J8 Clear CMOS Jumper
1-2 Close: Normal mode (Default)
2-3 Close: Clear CMOS mode

Virtually all motherboards I have ever seen use 1-2 for retaining data and 2-3 for clearing the BIOS.
