slackware 9.1 and scsi disks

[Alex Snow]

Hi all. I'm atempting to install slackware 9.1 on an old HP Netserver (I forget the model).  I booted the machine with tomsrtbt and it was able to mount the scsi hdds and cdrom and fdisk could see the hdds fine. so I booted the speakup.s and install.x bootfloppies and found that slackware couldn't see the scsi controler let alone the devices atached. during bootup right after the message giving the SCSI subsystem driver's version info I get an error like "failed to exec /sbin/modprobe -s -k scsi_hostadapter-errno 2".  The adapter is an adaptech (I forget which model though I can easily find out) and I think it's recognised as isa.  has anyone had a similar problem before? is there something I have to do to tell slackware to use the scsi controler? a look at /proc/scsi/scsi says "devices atached: none". 
thanks.
