I'd advise against using SilverLining, or _any_ general-purpose
third-party disk driver package, with Rodime disks... especially the
older ones.  Rodime's implementation of SCSI is rather quirky... their
older drives in particular have a non-standard implementation of blind
I/O transfers.  Drivers such as SilverLining, which assume a fairly
"vanilla" SCSI interface, will tend to time out or hang the machine
during SCSI-bus transfers to and from the Rodime disk.

Stick with Rodime's own driver/installer... it's less flexible than
SilverLining, but at least it understands the quirks of the disk and
won't lock up your machine.
