Hello Thomas,
Before I had that one I used hot-swapping :-) (Turn on System, wait until booted into DOS, replace Flashrom on Mainboard
with
another one (without turning off power), use AWARD flash utility to write experimental BIOS, reboot, test, replace with working BIOS, repeat :-) )
I used an even harder way in the 80's: with the EPROMS 27128C and a programming device. I had to insert the ROMS directly into the sockets. This really isn't fun :-(. And the sockets got loose. Someday I inserted an EPROM the wrong way. It smoked a little, but was still programmable after the disaster! How to you program the BOOT-ROM? I heard that it is fixed and not flashable. Is this right? Do you know a good method to test the ROM directly? [for example: just delivering the ROM data over the serial or parallel port of your dev. PC to the "test" Motherboard which in this case could run without ROMs [data comes over serial port directly into the sockets]]. Is there such circuit? What about timing problems? Bye
Bernhard
