This is one of the last BIOS upgrade for an older Biostar AT motherboard MB8500TAC ver 1. The file TAC0201G.exe is a compressed file that when extracted will give the actual AMIBOOT.ROM file, and a text file instruction. I followed the instructions and was able to recover my computer from an accidental bad flash bios that resulted in a dead motherboard. This bios update is one after TAC1023B
