Programming Flash ROM
All versions of the Titan III PCI EISA motherboard use Flash EPROM to
store the system BIOS. The advantage of Flash EPROM is 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.
Programming the Flash EPROM
Step
1
Turn power off. Make sure the computer has a working speaker.
2
Insert the floppy disk with the S729P.ROM file in drive A:.
3
Before DOS boots, press and hold down the <Ctrl> and
<Home> keys to reprogram the Flash EPROM-based AMIBIOS.
The bootblock code immediately reads the A: drive, looking for
the new BIOS information.
4
When the flash ROM has successfully been programmed, the
computer will reboot.
Boot Block BIOS Actions When you reprogram from system boot, the boot block BIOS code:
Reads S729P.ROM from the root directory of the floppy disk in drive A:.
Erases the Flash EPROM. Programs the Flash EPROM with the data read
from the floppy disk in drive A:. Generates a CPU reset, rebooting the
computer.
The bootblock part of the Flash EPROM is not programmed. Should you
inadvertently open the disk drive door or turn power off to the computer while
programming the Flash EPROM, the bootblock will be unaffected. Simply
turn power back on and begin the Flash ROM programming process again.
