   What are the limits of some of the modern controllers and bios's?  I
have run in to a number of cases where older controllers just give up or
provide head/track mappings that differ from one another, making it hard
to swap drives from machine to machine.  

     As long as track mappings are reasonable, the swap from one machine
to another need not result in loss of data.  (Other than the boot, that
is.)

     Having "lost" several controllers while swapping things from ISA 486
machines to to pentium PCI machines over the years, and just swapping
drives from machine to machine as loads, etc. change, I find this kind of
information quite important.

     I think the whole point of going to SCSI, is to be able to swap
drives as needed.  It isn't always as clean as one expects.
