Appendix A Boot Block Bios Utility - American Megatrends Enterprise-III User Manual

Appendix A
Boot Block BIOS Utility
Overview
The system BIOS for the American Megatrends Enterprise-III EISA VLB motherboard resides on an Intel
28F001BX-T Flash EPROM. Flash EPROM (Erasable Programmable Read-Only Memory) is a device that can store
information that can be easily updated without being removed from the system. The principal advantage of Flash
EPROM is that the information contained in it can be easily enhanced or updated via code on a floppy disk.
The Boot Block BIOS utility updates the Flash EPROM. If the system AMIBIOS for the Enterprise-III motherboard
needs to be updated, American Megatrends will provide a BIOS update file and the Boot Block BIOS Utility.
Why Use Flash EPROMs?
To effect a BIOS change in a system with a traditional BIOS EPROM, you must remove the BIOS ROM EPROMs
and insert new EPROM chips. Then you must reconfigure the system via AMIBIOS Setup.
The Boot Block BIOS code can be used to reprogram part of the system BIOS stored on Flash EPROM.
