Looks like the extra HPT366 controller is an add-on to the
motherboard, and the SMP part is hinting that you maybe have an
ABit BP6?

I have one of these, and your problem is that, with no other
drives installed (or even with drives installed on an ABit BP6
with the BIOS order set to "EXT" before "C", and "EXT" set to
"UDMA66"), you need to set the disk part of your "root" device
statement in your GRUB menu file to:

   hd0

You were assuming that BIOS device numbers follow the Linux
device naming scheme, and that is not the case.  The BIOS
numbers them starting from the first one in boot order.
