Hello,

here's a brief description of my problem:

I followed the steps according to the Cobalt-FAQ and everything went fine
to a certain point. But when trying to access the harddisk the machine just
gives an error and freezes.
The error I experience is the following:

pciide0:0:0: lost interrupt
        type: ata tc_bcount: 512 tc_skip: 0

All i know is the following:
The problem might be that the onboard IDE chipset can't handle the UDMA mode presented by the harddisk
which I don't applies in my configuration because both (controller and harddisk) agree on UDMA 33.

thanks in advance,
