The GENERIC kernel had all of the specific devices set as wildcards
and I had both controllers enabled. I tried the changes used here
and even a few more. wdc1 is not even recognized at boot so
I'm assuming the toshiba 550 only has a single controller.

atapibus0 came up on wdc0. Since the HD is on drive 0, I tried
forcing the acd0 to bus0 and drive 1 as well but nothing seems
to work at all.

Maybe this one is not supported?? The toshiba web site
claims this drive is ATAPI (Enhanced IDE) with 128K buffer,
20X max speed. The toshiba model number is XM-1602B.

Any other ideas?

Thanks,
