Flash ROM Programming
The American Megatrends Atlas 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 U86 switch 2 ON, or
•
•
run the AMIFlash utility.
Programming Flash from System Boot
Using the floppy disk with the new BIOS file, press and hold down the <Home> key to reprogram the Atlas
PCI Pentium motherboard Flash EPROM-based WinBIOS before DOS boots.
Using AMIFlash
AMIFlash is a DOS utility that is executed from the DOS command line. You can reprogram the Atlas PCI
Pentium motherboard Flash EPROM-based WinBIOS from the DOS command prompt using AMIFlash.
Set U86 Switch 2
Insert the floppy disk with the new BIOS in floppy drive A:. Set U86 switch 2 ON to program the Flash
EPROM.
