Flashing Without Floppy
First: Copy the Flash.exe and Bios copy to your local drive, for examples to C:\ ( C drive ). Just leave them there, and make sure the name of bios is less than 8 character. MS-DOS only recognised 8.3 format ( 8 character with 3 extension ).
Second: In motherboard's Bios setup menu, select the First Boot as CD-ROM, Second Boot Hard Disk, etc.
Third: Get your Windows 98 or Me CD-ROM or any bootable CD-ROM that loads into DOS mode. Don't use windows XP.... it doesn't work.
Fourth: Insert Windows 98 CD-ROM and reboot. The computer will boot the OS (DOS) from CD-ROM drive and you immediately select : Start with CD-ROM Support. Always!!!
Fifth: at A:\ prompt you switch to C drive by typing C: {enter}
C:\ type Flash.exe {enter}
And follow the instruction.
You are done.
I use this method 3 years for bios flashing VGA, Mobo, Raid. I don't trust floppy because of possible data corruption.
