Hmmm, maybe the machines where I've had odd behavior have been
mixed ide/scsi with bios set to boot from the 1st scsi.  But
some of the newer ones make you specify in the bios setup the
complete order of boot devices and don't like it if you swap
in a different sized device of the same type without running
the setup again.
