Shmingers Posted September 25, 2021 Report Share Posted September 25, 2021 Hi all, I've lurked here for a while now. This is a great forum to get info from. Thank you. Question - I've been working on XBoxes for a while now, and I just got my hands on a 1.0 with a dead Thompson drive and an even deader original Seagate hard drive (showing error 7). Upon opening the case, I realized it had an old modchip on the underside of the board: https://imgur.com/ZGJwShp Does anyone know what modchip this is? I'm mostly curious what that chip is. It's a very clean install and I've never seen one like it. If I tweak the laser pot and get the DVD drive working, will this modchip be able to boot Hexen? I have an Aladdin XT chip and a new laser coming in the mail, but they're a month away. I'm wondering if I can get the drive running just long enough to boot Hexen and install a new hard drive, maybe TSOP the box and then remove this older modchip. Thank you in advance!

SS_Dave Posted September 25, 2021 Report Share Posted September 25, 2021 It's called a 29wire mod and generally fitted to play backup's(copied disks), The chip is a prom (Program Read Only Memory) or possibly a eprom (Erasable Read Only Memory) and can not be updated to a newer bios. Yes you can use it to install a non MS-dash to the HDD allow you to flash the on board bios chip. Have you seen the OGXbox installation 2021 disk? it's more up to date than Hexen and in my view easier to use. Have a look here https://1fichier.com/dir/mX1kipIz Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

Shmingers Posted September 25, 2021 Author Report Share Posted September 25, 2021 Thank you very much SS Dave! I'm literally working to replace the thermal pastes on this console right now. Amazingly, it's also missing all but two of the mobo screws (!?!!?). I'll loop back on this thread if I'm successful. Cheers! Quote Link to comment Share on other sites More sharing options...
