Code to change BIOS boot sequence

I once analysed an old AMI 386 BIOS with 128-bytes of CMOS RAM. In that particular case there were two 2-byte checksums. The first was at CMOS RAM addresses 2E-2F. It summed the contents of addresses 10h to 2Dh. The second was at 3E-3F and summed the contents of addresses 34h to 3Dh and 40h to 7Fh. ...

What would happen if I remove the bios chip and power on...

I believe some old jumperless socket 7 motherboards would power up the CPU with an initially high voltage (because some socket 7 CPUs required as much as 4V) until they determined which CPU was present, and then the Vcore was reduced to the required level as specified by the BIOS. If the BIOS were a...

I notice that some motherboards encode the CPU core voltage jumpers in simple binary format. I suspect that in these cases the motherboard's power supply uses a D/A converter. Such a design makes it easy to fill in the undocumented voltage settings. The following example lists all the possible core ...

This is a list of manufacturers included in the man.dat file that ships with version 1.3 of AMI's motherboard identification utility: http://www.users.on.net/~fzabkar/BIOSutil/Ami/ManufV13/man.lst There may be some typos, either original ones, or as a result of unforeseen flaws in my decoding method.
