Asus P5QL-EM and Windows 7 graphics corruption/failed installation

Just a heads up to anyone with the Asus P5QL-EM – installing Windows 7 RTM without an addon graphics card (so essentially using the onboard graphics) will fail miserably. On the first boot, the display is corrupted (at least over DVI) and while booting in safe mode avoids this problem, the installer won’t continue properly. Another possible symptom is the Windows flag freezing during its ‘throb’ animation on boot. I didn’t see anything about this elsewhere online, but the issue may apply to other boards with the Intel G43 chipset.

I worked around this by installing an nVidia GeForce 8800GTS card I had lying around, and applying the 0601 revision of the BIOS: P5QL-EM-ASUS-0601. The board shipped with revision 0503, so I’d suggest that all system builders and integrators check their own boards before bumping to Windows 7.
