I've got the old PC-CHIPS VESA 486 board, the one you could order with any chipset, they just relabeled the chip. I'm trying to dump the BIOS from it so I can write it to another chip, to get a second identical board working. I've been searching around and maybe it's the heat, but I can't seem to figure out how to do this.
Awdflash has the most bizarre cmd-line switches, and the only version I could actually get to 'work' v1.2, gave me a dump of 0 bytes.
I tried NSSI, that gave me a 64K dump, but that seems small for a late model 486. Uniflash requires PCI and I can't download flashrom for DOS.
Is there something that works along the lines of:
DUMP -f bios.bin
I want to try to use the hot-flash method. Last time I did this was 10+years ago, so I can't remember any of the utilities I used. I seem to be stumbling at the first hurdle, can't even figure out how to read the BIOS.
I did have an eeprom programmer coming in the post from China, but it looks like the seller's been kicked off ebay, and today I've finally got a refund. So I'll have to order another.
