Re: Intel Mobile ICH4

[Craig Dooley <cd5697@xxxxxxxxxx>]

Strangely enough, this patch does allow the chipset to be seen, and in
dmesg, it says ad0 is UDMA100, but it's actually at BIOSPIO until using
atacontrol.  Is this just me being dumb, or does there need to be a
little more work to get this working fully?
