I have upgraded my Motherboard to an Asus P4C800.

I have 2 Hard Disks each bootable with Win2000 SP3. After
the upgrade, one disk reports "A disk read error occurred.
Press Ctrl-Alt-Del to restart" immediately after the POST.

The other disk boots successfully, and within Win2000 I
can read and write from both disks successfully.

If I return the problem disk to my old motherboard, then
it boots successfully.

If I run recovery console (I tried running fixboot) on the
new motherboard then it too can read the disk successfully.

Therefore I know:
1. The Hard disk is not damaged.
2. The Master Boot Record is intact
3. The partition information is intact
4. The boot sector is intact
5. The connection from the motherboard to the drive is
fine.
6. NTLDR is still in its rightful place.

Yet I cannot make it boot with the new motherboard.

Can anyone think why the boot process will not read the
disk correctly, but Windows2000 once loaded has no
difficulty?

(The problem hard disk originally had NT4.0 on it and was
upgraded to Windows2000)

TIA

Nick
