I recently purchased a Compaq Presario 900Z laptop and discovered it
used a ATI Radeon IGP 320M chipset.

>>From the pci output it looks like it uses ALi parts but at least with
kernel 2.4.18 it will not boot properly (Yes, Windows XP runs on it).
I tried to install Debian on it (2.4.18 kernel) and at first it hangs
with a machine check exception unless nomce is passed, then it will
give errors like this:

(doing this repeatedly)
hdc: status error: status=0x20 { DeviceFault }
hdc: DMA disabled
hdc: ATAPI reset complete
hdc: status error: status=0x20 { DeviceFault }
hdc: ATAPI reset complete
hdc: status error: status=0x20 { DeviceFault }
end_request: I/O error, dev 16:00 (hdc), sector 0

If I run fdisk -l /dev/hda I see:

hda: status timeout: status=0x80 { Busy }
hda: DMA disabled
hda: drive not ready for command
ide0: reset timed-out, status=0x80
hda: status timeout: status=0x80 { Busy }
hda: drive not ready for command
ide0: reset timed-out, status=0x80
end_request: I/O error, dev 03:00 (hda), sector 0

I have tried installing gentoo 1.4rc1 and RedHat 8.0 and both of them
failed to install as well.

Here is /proc/pci output:

Does anyone have any ideas on how to make this work, and/or does it need
further kernel support?

Thanks,
