I have recently installed the final version X3 Bios Chip with the pcb rebuild on an Xbox ver. 1.6b. When I post the blue x lights up on front panel but no video. The disable bios feature via the power button works perfectly, so does the backup bios via power and eject buutons, but when bios is enabled no video. I was wondering where the findal release batches all same bios 3.03 revision or where some lover or higher revision numbers? I have a feeling this might be what my problem is. Any suggestions? :?:
