Re: AW: [Xbox-linux] Cromwell booting

[fad <as...@fa...>]

I believe that the problem is due to not being able to get to the ISA(or is
it the X bus?) bus, and not being able to talk to the tsop when the LPC bus
is enabled,

to flash the tsop you need to do a software hack, without a lpc modchip,
ie 007 or mechassult, and flash the tsop after shorting some jumpers.

the ozxchip flashes the lpc mod, you cant get to your tsop by booting it and
then pulling off the chip.

FATX boot: This I didn't remember reading, probably because
I'm not interested in FATX support. I've always intended to
reformat my xbox drive and use a more standard Linux file system
(like ext3).

If you understand cromwell, perhaps you could suggest to
Chris some reasons why it doesn't boot, and some ideas to
fix his friend's system?

The only thing I can think of is that either:

1. Linux was not installed on the drive (but it sounds
like maybe his friend had it running at one time) or

2. the drive has been corrupted (or at least the boot record).

I would appreciate very much if you could explain why
this method is not possible, and how the flashing could
be done. I can't speak for Chris, of course.

Does the the problem have something to do with a conflict
between the motherboard mods to read and write the TSOP
and the mods to use the LPC modchip?

The OzXChip has a mechanism to disable the LPC flash and
enable the TSOP. Are you saying this only works for reading?

I am assuming Chris installed the OzXChip using the
advanced installation method, which allows the LPC flash
to be disabled and the TSOP to be enabled.

The instructions at http://www.xbox-scene.com/articles/tsop.php
do not cover the OzXChip. It would be nice if someone could
expand those instructions to include the OzXChip.

Unless there is a problem with having the instructions on the
xbox linux web site, I'd be glad to rewrite the instructions
to apply to cromwell instead of a patched MS bios. The only
thing I can't provide is the pictures.
