modify the POST sequence in bios
Posted: Thu Sep 18, 2008 11:50 pm
Hi,
Warm reboot is software initiated , while
cold reboot occurs if the reset/power button is pressed. The BIOS
checks the value at adress 0000:0472h. If it is 1234h, then warm boot
was performed, and the rest of the POST step is skipped.
I want to modify the POST step so it erases all the RAM memory if cold reboot is performed. is this possible at this stage of the booting process?
Any help/links are appreciated
