    The American Megatrends Enterprise-IV EISA VLB motherboard can be configured with a Flash EPROM. This Appendix explains how the Flash EPROM is programmed. You need to read this Appendix only if the Enterprise-IV EISA VLB motherboard that you received has a Flash EPROM.
  • Page 108 S87P.ROM S87P.ROM resides on a floppy disk and contains the updated main BIOS code. American Megatrends will provide this file when the AMIBIOS for the Series 87 Enterprise-IV EISA VLB motherboard must be updated. S87P.ROM must be present in the root directory of the floppy disk before the onboard Flash EPROM can be reprogrammed.
