Appendix A
Flash EPROM Programming
The American Megatrends Excalibur PCI Pentium motherboard uses Flash EPROM to store the system BIOS. The
advantage of using a Flash EPROM is that the EPROM chip does not have to be replaced to update the BIOS. The end
user can actually reprogram the BIOS, using a ROM file supplied by American Megatrends.
There are three methods for programming the Flash EPROM:
•
program from system boot,
•
set SW1 switch 3 ON, or
•
run the AMIFlash utility.
Programming Flash from System Boot
Using the floppy disk with the new BIOS file, press and hold down <Ctrl> <Home> to reprogram the Excalibur PCI
Pentium motherboard Flash EPROM-based AMIBIOS before DOS boots.
Using AMIFlash
AMIFlash is a DOS utility that is executed from the DOS command line. You can reprogram the Excalibur PCI
Pentium motherboard Flash EPROM-based AMIBIOS from the DOS command prompt using AMIFlash.
Set SW1 Switch 3
Insert the floppy disk with the new BIOS in floppy drive A:. Set SW1 switch 3 ON to program the Flash EPROM.
