 At least this is relatively trivial to change.  Mmm .. A7Pro .. 4 x ide
 channels.  ARC at Parramatta has 60g IDE drives for $295.  Do the
 math.  (hint - it's 18 times cheaper to get an AMD machine that's
 14x more powerful than an E250 with 180g of RAID5 DASD). *   ; )

 Do people still use non-Debian distros ?

 Sadly this is not the case with the 1542B.  The big difference between
 the 1542B and the 1542CF is that the CF had the Ctrl-A option at
 boot .. at least, this is how I remember it from my Novell days in
 the early 90's.    The 1542B required strappings and MSDOS floppy
 boot disks and running and screaming and chickens' innards against
 wall and the like.

 By default, the 1542B chose irq 10 (and DMA C800) .. the IRQ
 component, at least, was the same as that used by most NIC's of
 the day -- which caused all kinds of problems.

 Bah.  I remember having to use DEBUG under DOS 3.2 in order to
 format my hard drive.

 Jedd.
