on
A new motherboard was installed on a dell dimension 8400 and it boots to the error 0x0000007b

We cannot run a chkdsk because it says hard drive may have unrecoverable problems, cannot run...etc

Cannot run boot cfg because it cannot find a boot sector

Cannot run fixboot because it cannot find a boot...etc

Must be able to fix this because the computer is configured with special software and set up

I believe your Windows install is missing the ICH driver to find your SATA disk during boot

Is this an identical motherboard to the one taken out?

Did you make a note of all the previous BIOS settings from the old motherboard? What mode was the disk controller set to?
It maybe as simple as setting the controller to the correct mode. Set for ATA if currently AHCI and visa versa. Almost ALL XP installs would be in ATA mode but the board probably defaults to AHCI

I changed the sata setting to combo from raid

Commented:
And is Combo what it was on before?

Commented:
Yes. I also tried each of the other settings to see if any would work and none work.

So...
fully working machine, no issues.
Motherboard dies.
Replace with EXACTLY the same motherboard.
Now cant boot due to 0x0000007b errors.

Is that right? Not missing anything?
You changed NOTHING else?

Commented:
From Dimension 8400 service manual:

Drive Controller
Identifies and defines the SATA controller settings for RAID. You can set the SATA controller to RAID Autodetect/AHCI, RAID Autodetect/ATA, or RAID On.

The default is RAID Autodetect/AHCI but is often changed when XP is reinstalled to RAID Autodetect/ATA to simplify XP installation.

The only missing things is the memory tested bad. We vreplaced the ram. We think when the old motherboard shorted out it took out the ram and corrupted the hard drive's boot sector

What is COMBO? Not seen that mode on a SATA controller in an 8400
