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
