AlaskaCC Posted October 15, 2018 Report Share Posted October 15, 2018 A friend gave me a v1.0 board that was causing problems for him. I put it in a standard early case, attached everything and proceeded to test it. I wanted to update the BIOS (TSOP) so I attempted to run the Hexen DVD. The DVD tray would open, I placed the disk in the tray and pushed the button to close. The Unleash X menu continued to show "Open". I tried this with two known good working DVD drives - one a Samsung and the other a Hitachi.. I changed cables and PSU with no difference. I also checked to see if there were any bent pins for the DVD power cable. All good. I switched-out the power button/DVD drive button harness. No difference. Then I tried a good Thomson DVD drive. Everything worked flawlessly.. What is that all about? Is there a different command structure for the early v1.0 boards that limits which DVD drives will correctly operate with them?

Forlorn Penguin Posted October 16, 2018 Report Share Posted October 16, 2018 Xbox DVD drives are just old and shitty. Some of them will simply fail to read certain discs, authentic or otherwise, for no reason, while others can read the same disc fine.

KaosEngineer Posted October 16, 2018 Report Share Posted October 16, 2018 Sounds like a bad power/control cable (all yellow 12 wires), not the IDE cable. This cable carries power and status signals to the PIC System Management Controller (SMC) about the tray status. The picture above should state at DVD, not at MB. The motherboard end of the able has two more pins 13 and 14 with no connection (N/C). Quote Link to comment Share on other sites More sharing options...
