Hi - I hope I'm posting this in the right place. Forgive me if I'm not doing this right.
I have an old Dell 1600SC PowerEdge server with 2 SCSI adapters.

One adapter is on the mother board. - It is an LSI 'non-raid' SCSI adapter and about the only thing I can offer is that it displays "MPTBIOS-5.06.04" during POST.

The other adapter is on a PCI-X card. Also by LSI and it is a PERC4 SC RAID adapter.
My SCSI disks are in a hot-swap drive array and are connected to the controller ia a cable with only connectors on each end.
Obviously, I only use one adapter at a time.

The LSI PERC4 adapter (in the PCI-X slot) works flawlessly. - I was able to install Slack-13.1 with no problems and it runs really great.

My problem is that Slack 13.1 CD doesn't seem to recognize my on-board SCSI adapter. - It looks the kernel is seeing the LSI adapter and loading the Fusion MPT base driver 3.04.13 but then there's an ioc0: error - someting about a doorbell ack timeout.

After I finally boot, a 'fdisk -l' shows nothing.

Am I missing a module somewhere or what? - It's really not that big of a thing except I would like to get it working to run some bench tests between the on-board SCSI and the PERC4 adapter(s).

Thanks in advance.

Sounds like you are short of kernel capability. Find what you need, and load modules or compile in. instead of fdisk -l try cat /proc/mounts

Try a few other live cd's. Try opensuse first. I have found it to be the best one for server support by default.

Also Dell site did have drivers for linux for that I believe. Might have to go with scientific or centos.

Thank you all for your input.

After making my original post I tried the Slack 12.0 install and it worked fine with this "questionalble" SCSI adapter.

Looks like this is now a kernel issue somewhere between Slack 12.0 and 13.1.

I'll have a look around in that area of the forum.

Thanks again for your advice.
