  • Page 70 S752P.ROM S752P.ROM resides on a floppy disk and contains the updated main BIOS code. American Megatrends will provide this file when the AMIBIOS for the Apollo III ISA motherboard must be updated. S752P.ROM must be present in the root directory of the floppy disk before the onboard Flash EPROM can be reprogrammed.
