Цитата:
CMOS 3Eh - AMI - Extended CMOS Checksum, High Byte
Note: this checksum covers locations 34h - 3Dh, but is not used by some
later AMI BIOSes

Цитата:
CMOS 3Fh - AMI - Extended CMOS Checksum, Low Byte
Note: this checksum covers locations 34h - 3Dh, but is not used by some
later AMI BIOSes

Цитата:
CMOS 7Ah - AWARD - EXTENDED CMOS CHECKSUM (high byte)
Note: Award's extended checksum is the arithmetic sum of all the bytes
from 40h (64 decimal) through 79h (121 decimal). [42h-79h for v4.50G]

Цитата:
CMOS 7Bh - AWARD - EXTENDED CMOS CHECKSUM (low byte)
Note: Award's extended checksum is the arithmetic sum of all the bytes
from 40h (64 decimal) through 79h (121 decimal). [42h-79h for v4.50G]
