I just read the BIOS guide on tomshardware. In the end, the guide write that:
Once the update is complete, turn your PC off.

When the update is done, you SHOULD NOT turn off the PC. This is a good way to kill a computer. Especially with nforce2 chipset. AAMOF, most nforce2 BIOS upgrade procedure show up a little screen after flash that tell the user to not power off their computer after the flash, until it has posted again..

And if the BIOS failed, and you turn it off, trouble guaranted..


The correct procedure should be;
-flash..
-reboot when asked..
-let it fully post until the screen show up an error message that CMOS checksum has changed..
-then from there do what ever you want with your BIOS..

i have same problem
my pc interrupted during update bios
i try with cmos clear it wasn't work
i try boot block jumper procedure
then nothing shown only sound 1 long beep pause and 2 short beep
then the fdd searching for something
i put my update bios disk that i used for boot block jumper procedure
but still won't work,
my cpu fan work, cd room on, fdd on,
the power light on, the system light on but no POST at all
i want to ask
if i should clear default bios do i have to turn on my pc
when the cmos battery is out or just take off the battery
without turn on my pc ?
how long i can take off the cmos battery
before i can do the boot block jumper procedure
with the latest update bios disk?
is the procedure i work on it is the best way to recovery my bios failured
or is there any way to fixed it without replacing the mobo

i use processor intel 2,4 ghz, mobo with intel 845 chipset 512 cache,
533 fsb, 128 ddr2 memory , 40 gb ata 7200 rpm others are standard

Usually, when the power is interrupted during flashing, then the BIOS is more likely to be dead..

To fix, either get a new BIOS chip, or have this one reprogrammed.

There is some business specialized in reprogramming BIOS.

sorry i dont mean in just forgot the caps lock is on
the boot block jumper procedure is simple
set the jumper to the position 2-3
insert the latest update bios disk to fdd
turn on the pc
then wait till the process on fdd finished
turn off the pc
set the jumper back to normal position
turn on the pc wait till POST appear
walla the bios should be recovery
but i don't guarrantee this will work on
every failured bios because
in my mobo it didn't work
any advice? thanks

Hahahahahaaa.. Hot Flashing, I haven't heard that term or technique in SO long. It's cheaper now-a-days just to buy a new BIOS then risk zapping the board.

If it's an Abit mobo, I know for a fact new BIOS chips are easy as hell to get after market.

You can try hot flashing it, but you risk killing your mobo completely.
