I don't know what I did wrong. I had a defective x1900xtx so I sent it to ATI and they replaced it for me. Meanwhile, I had the ATI x800gto in the system for now. Well, I put back the x1900xtx in the system and when going through the boot sequence, I recieve this error:

No enough Space to copy PCI Option ROM [05:02:01]
Press F1 to Resume

Here's a picture of it:


The system comprises of the following:

PCIX Adaptec 2 channel card ( 1 channel is being used ) and this controller is my 1st boot device since it has my OS.

I have a backup WD 300G drive on the SATA connection as well as my DVDRW ( Plextor )

The Dell monitor I have has a number of USB and memory slots on it as well so I think the boot sequence also refers to those ( not sure ).

Remember, I didn't have this problem before until I put the card back it.

Any clues.?

When I press F1, it boots into Windows without a problem.
