Thank you so much for everyone's replies, very thorough answers and knowledgeable members, I do believe there is a hardware problem with the motherboard. I literally confirmed all components except for the motherboard are working normally. I will keep that console around for parts, since the power supply, hard drive, DVD drive and shell are in good condition. I've moved on and switched the mod chip over to my working Xbox and everything is working very well. I installed the dashboard I believe through the Hexen 2020 disc and it is booting into UnleashX. I installed a working 120GB IDE drive and formatted. I am struggling a little bit with running ISO files off of the hard drive after FTPing them over. Any advice here? I heard you can extract them, but I'd rather leave the ISOs intact.

So I've given up trying to save the error code 7 Xbox. Nothing seemed to be working. So I transferred over the modchip to my working Xbox, and currently booting from Hexen 2020, and formatting a new IDE hard drive I put in. Could you please elaborate on the cold boot bug? What is this and what causes this? How do I go about flashing the TSOP with a different BIOS? I thought the idea if the modchip was that it replaces the factory BIOS. PLEASE excuse my ignorance, I am extremely new to Xbox modding.

Tried all components in another Xbox that is known working and there are no issues. I have tried everything at this point, so it has to be the motherboard.

Thanks for your reply. I actually noticed the DVD drive power cable was a bit loose on the board so I pushed it back in, but no change. Still error code 7. Interestingly, I have another Xbox with a known good DVD drive that I swapped in, and it still returned an error code 7. I think it's safe to say it's either the motherboard or the power cable itself for the DVD drive. I bought an IDE to SATA and it arrived, so I'm going to swap in a known good SATA drive and that should completely rule out hard drive issues. When I cold boot with the Hexen disc in the drive, it does not boot to disc, goes to error code 7. It sounds like it tries to read the disc but doesn't sound like typical drives, kind of spins up, spins down, spins up, spins down.

The IDE connector on the mainboard looks fine. Checked voltages on Molex, getting a healthy 5V and 11.86V, so the drive is getting proper power.

Thanks for the reply! I can hear both the disc drive and hard drive activate, typical dvd drive read noises alongside with brief hard drive sounds but then stops. Jumper settings are always set to cable select. How can I check correct power from molex? Just use a multimeter with the Xbox on? What do dry joints look like on the main board for the IDE connector?

Thank you everyone in advance for all the help. I was given an Xbox and it doens't work, showed error code 07, I assumed dead hard drive so I wanted to do a hard mod. I have an early revision Xbox, just installed the Aladdin XT hard mod with EvoX BIOS, the install was a success and I get the logo in the top left on boot, followed by an error code 07. I have tried a few different things as I know that is the result of a hard drive time out. I've tried multiple IDE hard drives, known good IDE cable, known good DVD drive, I've unplugged the hard drive data cable and it still shows error code 07. I have a Hexen 2020 disc at the ready burned using Windows built in tool. I have ordered a few things; IDE to SATA converter to test with a known good SATA drive, and 80 wire IDE cable. Please let me know what I should try next. I am starting to believe the hard drive is actually fine, because when I unplugged the data cable it did not switch to an error code 8. Thank you!
