post2 , hello all
last week i asked about reworking the checksum in
an AMI on PHNIX BIOS ROM for an AT.
the responce i got was to add all bytes , MOD 256
and change any un-used byte to finish up with ZERO.
my question is : is this the same as an 8 bit add
of all bytes =ing 00.
if so Y dont any of the BIOSes we have add up to
00 or N*256 eg 15A70
thanx again JEFF
