Mine are defined by the bios as sata drives, but have no clue if they
are being treated as pseudo SCSI drives or what. When I am at the kernel
boot stage I see /dev/sda and /dev/sdb flash by. Check this from dmesg:

SCSI device sda: 398294975 512-byte hdwr sectors (203927 MB)
sda: Write Protect is off
sda: Mode Sense: 00 3a 00 00
SCSI device sda: drive cache: write back
SCSI device sda: 398294975 512-byte hdwr sectors (203927 MB)
sda: Write Protect is off
sda: Mode Sense: 00 3a 00 00
SCSI device sda: drive cache: write back
 sda: sda1 sda2
sd 0:0:0:0: Attached scsi disk sda

See?? This is what is first found.... although the order is buggered up,
then I get this later on:

hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(66)

at the last I see this, where the harddrive is still labeled as the
first SATA device, instead of being the second.

I'm a little confused by all of this. Whatever happened to plain
vanilla /etc/fstab running the show??? It's like being in the Twilight
Zone, while seated comfortably in an old Electra-Turbo Prop, looking out
on the wing and seeing some hairy figure ripping off the engine hatch
making sparks fly. 

Even with dmesg, I don't know what to believe. I guess I could grab the
Sky Marshall's gun, open the emergency wing door hatch and shoot it. But
then I'd have to take the strapped down gurney ride and miss New Years,
so I'll refrain. I'll unlock this door with the key of imagination.
Beyond it is another dimension. A dimension of sound. A dimension of
sight. A dimension of mind. I'm moving into a land of both shadow and
substance... of things and ideas. I've just crossed over into
the ...Twilight Zone.  <dah! dah! dah! daddada-duh!>
