CAN'T BOOT BACK UP, PLEASE HELP ME

[HansG]

While in the process of trying to put a 6800 Ultra video card into my old PC, I made a couple of changes to the BIOS and now I get the message below when I boot up. I can't get past this message and don't know what it's trying to tell me.

BIOS ROM checksum error
detecting floppy drive A media
insert system disk and press ENTER

I tried to reset my mainboard back to the default settings by resetting the jumper but I keep getting the same message above. I'm following the instructions for resetting the jumper according to the manual but is something else going on here?

Any ideas what going? Any help would be greatly appreciated.

Sincerely,
Hans

Change your boot order to floppy>cd>hardrive or ide 0 and see if that helps. When you use the cmos jumper, it changes everything back to the original settings. If that doesn't work, make the hardrive the first device.

I would but I can't even get into the BIOS to change it.

Your very old PC may have a weak PSU that cannot power the 6800 adequatly and prevent the computer to run at all

I don't know about that. I just put a 430 Watt power supply in that old PC and ran the PC WITHOUT the 6800 for a few weeks before adding it to the mix. I would think 430 Watts should have been enough to run it. I have since put the old card back in but it looks like the damage is done as it does the same thing. So if it wasn't how can I get past this error? From what I'm finding out I may have blown the BIOS chip?

"BIOS ROM checksum" errors don't appear out of nowhere. They happen after a BIOS flash update failed, or, much more often, when the RAM isn't working right. This in turn may be because it is genuinely bad RAM, or because you manually chose settings and timings that don't work.

First stop: Clear BIOS settings (aka "CMOS") via jumper or by pulling the battery. Either needs to be done with the PSU physically off or unplugged.

You can also try just one stick of ram in each ddr slot, one at a time.

I can't reset the BIOS with the jumper or unplugging the battery, I've tried several times. I must have blown something so I'm going to flash the BIOS tonight. I'll try that deal with the RAM but I think it must be BIOS related. I did change a couple of BIOS settings but if the settings were wrong I should have been able to reset the BIOS back to the default settings.
