I have no idea if this has been mentioned yet, but I was reading about one user claiming that his video card worked with the A05 BIOS for the 9300. I figured I would check it out for myself, so I reverted back to the A02 BIOS on the BIOS hack disc. To my surprise, even with the A02 BIOS for the 9300, the video card was identified and even ran at full clock speeds. So I upgraded to the A05 and the card still works perfectly.
Is this true in all cases? Is the hacked XPS BIOS really even needed?
This is great news to be because my XPS BIOS was having a conflict with my SATA HDD and I had to run a thorough POST to get it to identify the HDD, causing extremely slow boot up times. Now, I can revert back to a quick POST with the 9300 BIOS.

EDIT: I just searched this thread and saw that a couple users had figured out that a XPS BIOS isn't needed.
