[20070109] Jared's NetBSD/xbox project page
Jared has setup a page for his NetBSD-hacks on the Xbox. (Please note that the Xbox port is actually a part of the i386 port, I'm not aware of any changes to make it a separate port - all that's specific to the platform is the kernel).

Jared's page includes the requirements for the port to run, a list of what works and what needs more work, where go get it, where to ask for support (port-i386@), and more.

[20070107] NetBSD support for Microsoft's Xbox committed (Update #2)
As reported a few days ago, Andrew Gillham is working on getting NetBSD to work on Microsoft's Xbox game console. Jared McNeill has joined him and after some serious sessions of hacking and cursing, the most essential bits to run NetBSD on the Xbox are in NetBSD-current now.

Quite some work also went into getting the nVidia ethernet nfe(4) driver working properly, getting a xboxfb driver to allow X to run, and getting an Xbox controller USB driver (looks like a mouse) written.

For bootstrapping, Andrew tells me that `` a hardware modchip is not needed to boot NetBSD. You only need to do the "soft mod" that involves booting a game save with a game like Mech Assault and crashing it with a buffer overflow. You do need the original game and a memory unit and the game save on the memory unit.''.

Maybe someone can assemble all the neccessary bits into a "Getting NetBSD going on Xbox" document next...

Update: Jared has also uploaded a bootable CDROM, archive for a NFS root filesystem and some instructions. You will still need a modded Xbox, see here and here for some details.

Update #2: Andrew also has some files up, including a picture of his pimped-up xbox which shows the Xecuter X3 LCD display, which is supported by the xboxlcd driver.

[20070106] Using your Xbox 360 HD DVD drive with NetBSD
Jared McNeill bounced me this gem: The Xbox 360 comes with an external HD DVD drive that's connected to the Xbox via USB. Using the drive on a NetBSD box via USB is easy, but accessing the data on the HD DVDs was not possible so far. After Reinoud Zandijk's last round of changes to the UDF filesystem driver to bring it upto UDF 2.60, the Xbox 360 HD DVDs' data can now be accessed from NetBSD:

Please note that while the HD DVDs' can now be accessed, it is still encrypted, but it's a start. Jared tells me: ``Basically, the video files on the disc are encrypted and wrapped in an MPEG program stream. You need to extract the title key (also encrypted) from the disc to be able to decrypt the program streams. The video may be either MPEG2, VC-1, or H.264. I can't remember off the top of my head what formats are allowed for audio''.

The changes to UDF should theoretically work for BluRay DVDs also, but this hasn't been confirmed due to lack of hardware - maybe someone can send some feedback on this? Reinoud has the following to say about this: ``BluRay discs have most likely UDF 2.60 filesystem on them since this is the first standard that mentions this disc type. For BD-ROM and BD-RE this should be equal to version 2.50. On BD-R either VAT or logical overwrite is used but for read-only access this shouldn't differ. Testing it of course would be good.''

Reinoud also points out that the next points on his roadmap include optical disc formatting, creating newfs_udf(8), fsck_udf(8) and write support.

[20061225] NetBSD/Xbox progress
Andrew Gillham has been working on a port of NetBSD to the Microsoft Xbox games console, and he has sent a status report with request for help and dmesg output. There's also a test kernel available, with some instructions on how to boot it. Seems an Xbox with a mod chip is needed, though.

[20050727] FreeBSD on Xbox
So there is a BIOS(replacement) for the Xbox that can boot from a mbr, and there's a port of FreeBSD now. Cool! Anyone want to port NetBSD too? Go for it! Links: Xbox/FreeBSD, Xbox tech details wiki, official site (mirror), torrent of Live CD. Cheers!
