I have a machine with the following two drives (as listed in dmesg):

ad0: 12427MB <Maxtor 91303D6 GAS54A12> at ata0-master UDMA33
ad2: 76319MB <Maxtor 6L080P0 BAJ41G10> at ata1-master UDMA33

ad0 is the boot drive.  It is recognized by the BIOS, obviously, and
has been in the machine for some years.  ad2 is a new drive I just
added to the machine yesterday.  It is not visible to the BIOS at all.
If anyone can posit a reason it would not be visible to the BIOS, I
would like to know the answer.  The BIOS supports LBA and ad0 is more
than 8GB so it wouldn't appear to be the 8GB limit, and the next limit
I am aware of is comfortably larger than 76GB.

There were quite a few BIOSes that had a 32GB limit; thus,
HD manufacturers contrived a (usually) dual-jumpered configuration
to limit the reported disk size to 32 GB for these boards.  In
my experience (which is not extensive) these would be relatively
early ATX boards (Pentium II, early K6/2's, etc.).
