novice needs help with "wdc1 not found at 0x170"

[Mark Senn <mds@xxxxxxxxxxxxxxx>]

Questions,

DOS recognizes my C: and D: disks fine.

The C: disk contains DOS stuff, the D: disk is newly formatted but
contains no files.  I'd like to put all FreeBSD stuff on the D: disk.

When I try to use the FreeBSD boot disk I get:

           [...]
           wdc0 at 0x1f0-0x1f7 irq 14 on isa
           wdc0: unit 0 (wd0): <QUANTUM LP240A GM240A01X>
           wd0: 234 MB (479349 total sec), 723 cyl, 13 head, 51 sec,
             bytes/sec 512
           wdc0: unit 1 (wd1), <QUANTUM MAVERICK 540A>
           wd1: 516MB (1057392 total sec), 1049 cyl, 16 head, 63 sec,
             bytes/sec 512
           wdc1 not found at 0x170

I've RTFM but haven't totally UTFM [understood ...].

I'm not sure if there is something that I need to reset in the DOS
system setup program or something special I need to do since the
D: disk has over 1024 cylinders.  Clues suitable for boneheads
would be appreciated...feeling pretty frustrated and intimidated
about all this.

Thanks for any help,

Mark
