Would if I could. This isn't a PCI card, it's an RPX module. There's
only one slot it will fit into. Like I said, if I startup the Netware
installer it works fine, DOS works fine, haven't tried windows, but I
assume it will work if DOS works. Linux doesn't work. Linux is the only
one that tries to seperate the two devices (the SCSI and the RAID).
I have an email into AMI, but they're not responding, so I guess I'll try
and call them. They're supposed to support Linux now.
