two ata-related problems

[perryh at pluto.rain.com]

Two questions about installing FreeBSD 8.1 on a Dell Precision 420
(yes, I know it's old):

1. Should FreeBSD 8.1 be able to recognize a 100MB ATAPI Zip drive?
   I'm not finding it in the dmesg, although BIOS Setup recognizes
   it.  (It and a CDROM are on the secondary IDE channel; I've tried
   with each of them as master and either way the CD is recognized
   but the Zip is not.)

2. It currently has the original A01 BIOS.  I'm going to have to
   update that, because it doesn't recognize the 320GB drive I've
   added as a new boot drive.  With the 320GB installed as unit 0
   (master) on the primary IDE channel, the A01 BIOS won't even
   recognize the previously-working 40GB drive which is now unit 1;
   so the BIOS disables that channel entirely keeping FreeBSD from
   seeing those drives either.

   A BIOS upgrade should be straightforward, but while Googling
   I ran into a posting where someone apparently had a lot of
   trouble with a BIOS upgrade for one of these of boxes.  Thus
   the question:  Has anyone here had any experience, either good
   or bad, with running FreeBSD on one of these with an upgraded
   BIOS?  If so, which version?  I found A06, A07, A10, A11, and
   A13 on Dell's FTP site.

dmesg (from a USB boot) attached.  The reported 320GB (on an add-in
card) is a twin of the one described above that isn't recognized on
the primary on-board channel.  I want them on separate channels to
improve mirroring performance.
