I have this exact same problem with _some_ disks on my Promise PCI
adapter. My Maxtor drive works, a 32x CDRom worked as well, but a
Seagate and a Quantum both hung the box. I haven't found the problem;
but it might be related to timings on the interface, so that some disks
might work, and others not.

This means the driver is not able to acces the controller for ide1.
That might be a problem with the IO-port addresses.

Also, you might want to try patching your kernel with Andre Hedrick's
multi-platform uniform IDE driver (look at
ftp://ftp.kernel.org/pub/linux/kernel/people/hedrick/). You _might_
need additional patches to get it to boot; if so, get back to me, and
I'll produce a diff against my working kernel.
