i had an rz55 running from a media vision proaudio spectrum's scsi port
running fine. it was not a boot drive though, i was booting from an ide.
the drivers for everything were in the kernel. i had it in two systems,
both 486s. in the first, linux would boot until it reached the scsi
system, initiated the spin up of the drive and the rebooted the computer.
the second time through it had now spun up and it went on fine. the
second system (different mb/bios) just paused at the spin up and waited
for the drive and then went on.

i only mention all of this to let you know that it can work somehow. it's
possible that something between the drivers for that particular scsi card
and linux doesn't want to spin the drive up.

on a related note, i seem to recall some dos based program called rzspinup
(or something like that) that would cause the drive to spin up on system
boot.
