Hi,
I've got a mainboard I didn't find a way to get a video signal even if it boot and I opened a thread time ago on it ( Another 486 board identification/debug help ). I'm not creating this as a double thread but more as focusing on the opportunity to flash any Amibios 28-pin old style (in this case a MX 27C512DC-15 with VPP=12,5V) where I would need to try downloading or flashing some similar bios from other boards to a new 28-pin eeprom. Considering most software seems to not work with such old eeprom/mainboard and I can't even boot it (the board is powered, psu run, everything warm up, no signal) should I need to buy an external flasher, is the only way or I can use a modern larger eeprom socket to try flash something?
Thanks
