BTW... give a thorough look at
xbox-linux.sourceforge.net before you consider doing it, read all the documentation... when i went back and took a look after replying to this thread it appears that their documentation for a Debian install looks far simpler with much less hot swapping involved.
And do realize that it is very important to backup that x-box HDD, as far as i can tell your x-box will become a ful time computer once the linux install is finished, there doesnt appear to be any LILO or GRUB system for dual booting between linux and gaming. looks like it will require a HDD restore to be able to play games again to me, so definitely get an idea of what are you doing by reading all the info they have there
EDIT : bleh on further review i found this in the FAQ:
Will I still be able to play games once Linux is on my hard disk? ... That depends on the solution you choose. If you run Linux through the XBE bootloader on an Xbox with a modchip, there will be a software-based dual boot solution. It will also be possible to run Linux from a CD without having your hard disk modified at all.
it all looks pretty good to go to me, but id still back that HDD up
