Reformat Dell XPS 400

During my reformat startup my keyboard works until I get to

3 choices; F3 to quit, R for repair and enter to continue.

At this point my keyboard does not work......

I tried 3 different keyboards each on multiple restarts and all keyboards quit at the same point.

I can't get past this point, any ideas?

Not sure... have you tried a USB keyboard instead of a PS/2 Keyboard?  Or a PS/2 Keyboard instead of a USB keyboard?
Does your computer have a PS/2 port and have you been trying only USB keyboards?  I've had this problem with USB keyboards during system installs before.

The computer only has USB ports so I can only use this type of keyboard.

Have you tried:
1.  Different USB Ports?
2.  Slipstreaming a new CD with Service Pack 3 included (use application to create a slipstreamed CD).

I tried all USB ports on front and back of machine.

How do I use slipstream?
XPS400 system board has PS2 keyboard connector (serial type):
If usb ports failed, you might have to call Dell for a PS2 adapter to use. But let try suggestions above first.  
Can you get into the BIOS (Press F12 when the computer first turns on and Choose to enter setup)? If the keyboard responds there, make sure USB legacy or USB keyboard support is enabled in the BIOS. If the keyboard isnt responding there, then it's the keyboard or USB port/controlle that failed. Try several different USB ports to see if any work. If not, it's probably the keyboard.

If you can get into the BIOS and those options are set as I specified, then maybe the computer is locking up? Try running memtest86+ on it just to be safe.

I did not find anything for legacy settings pertaining to keyboard.

I am doing a diagnostic on it with built in feature, I doubt it helps but at this point I have nothing to lose.

It takes 20  minutes and I can't do anything until it is complete.
Cool. I don't know if it'll find anything, but it rules out some common things even if it passes.

The weird thing is that every port works with the mouse, I know because the light illuminates on the bottom of the mouse....the keyboard does not?
Sounds like a keyboard issue. You should at least be able to toggle the numlock key LED. If that isn't responding, then the keybaord isn't sending data to the computer.

I tried multiple keyboards each about 4 different times. The key board works up to the point of selecting enter for the format to begin. All keyboards function up to this point.
newbnewAuthor Commented:
Okay, I tried everything I can think of and nothing has worked yet....

I changed a setting in the BIOS from achd or something like that to combination...upon reboot the keyboard functionality worked.

Thank you for leading me in the right direction.
