This has me racking my brains out. I recently purchased a new 486 motherboard because my old one died.
I transfered everything over and when I started it up I got a hdc failure, so I replaced the disk controller card, but I still got a hdc error and I could not get into the bios setup to change anything, so I brought the motherboard back to the store and they said it was running perfectly. I asked them to set the bios to boot from floppy because the hard drive is not bootable. I took the motherboard home and set everything back up again and still I get hdc error hit F1 to resume, but hitting F1 does nothing. I tried to clear the bios to return to it's default state, but now I get CMOS checksum error and a video error, I am at my wits end on what to do, I really don't want to drag it back to the store.
I'd rather fix it myself.
my motherboard is a vl-bus 486 with a 66 DX2 chip, it's an AMI bois dated 1995. I saw it working at the store but that was without my video card or hdc card.
Please point me in the right direction
