I think there is nothing wrong. FreeBSD finds both of your hard disks. One is
234MB and the other 516MB.

wdc1 is not any hard disk; instead, it is hard disk controller. I think
you have only one IDE card so you have no problems.

FreeBSD bypasses BIOS and handles 1049 cylinders with no problems. I have
my FreeBSD on a Quantum Maveric 540A too.

However, one thing you should pay attention : the DSAP jumper on the 540A,
and/or the other jumper on the other one. I connected both hard disks with
these jumpers connected. Strangely enough, under DOS everything seems to
be fine no matter how I connect these two jumpers. But under FreeBSD,
I must connect them right otherwise either I fail to fdisk or disk time-
out occurs. (I think they are master/slave jumpers ?) If you still fail
to identify 2nd hard during installation, you may want to try another
IDE controller card. The old IDE controller cards may have problems when
connecting 2 hard disks.

That's my experience. Your controller is identified correctly. I have one
monterboard on which FreeBSD CANNOT find wdc0 and wdc1, which I still fail
to make it work.
