Since you have access to the internet maybe trying this will work for you.
I flashed my BIOS and now the machine is dead. What can I do?
If your BIOS appeared to flash properly, then you had one good reboot, but all subsequent reboots have left you with a blank screen, you most likely failed to use your one chance to reset the CPU speed from the default 500 MHz back to the proper clock setting. This results in a machine that won't go. You need to clear the CMOS and then immediately enter SoftMenuIII in the BIOS and set the correct CPU speed.
Otherwise, you have probably somehow corrupted your BIOS whilst flashing to the later version. If you are lucky, the boot-block BIOS will remain, which means you may be able to reflash your BIOS using a bootable floppy. Your screen may remain dead during this activity, and so you might have to guess when the process is finished (wait 5-10 minutes). You must do the following:
1. Create a bootable DOS floppy using Windows 95 or 98
2. Remove all memory management files from the floppy disk and AUTOEXEC.BAT
3. Download a new version of the BIOS file and copy to the floppy disk (don't use the version which killed your BIOS - it's probably corrupted!)
4. Download a new version of the AWDFLASH.EXE file and copy to the floppy disk
5. Add the line "AWDFLASH newbios.bin /py /cc /sn /cd" to the end of the AUTOEXEC.BAT file (where newbios.bin is the name of new BIOS file)
6. Power off your machine, insert the floppy, power up
7. After five-ten minutes, remove floppy and reboot!
