I need to get to the command line to do a 'modprobe DAC960' on installing Fedora.
Is this possible ?
Many thanks in advance,
Aaron

Is the Fedora installer not allowing you to install to hard drives located on your RAID card?
If that is the case, I'm afraid Linux (the kernel, not Fedora) does not support your RAID card. A quick Google shows the last driver was compatible with the 2.4 Linux kernel. Fedora 14 uses the 2.6 kernel line.
Manually running modprobe will not work as there is no "dac960" kernel module for the 2.6 kernel and hardware detection is automatic these days (versus 2.2/2.4 kernels).

FC4 was working. post FC4 is not.

FC4 was 2.6.11, looks like it may have been jettisoned later.

Right. How does the HW detection work now ?
Thanks,

Kernel drivers come and go. Sometimes they are completely rewritten (and renamed). Unfortunately for you it seems support for your card is gone completely.
If you wish to use a newer Fedora release it will involve chasing down someone to help you. I'm not a kernel developer so I can only show you the way. You should start by getting your PCI ID of your card and posting your findings to the kernel[1] list.

Mainly off of PCI ID.

Are you sure ? $ uname -r 2.6.35.11-83.fc14.i686 $ grep -i DAC960 /boot/config-2.6.35.11-83.fc14.i686 CONFIG_BLK_DEV_DAC960=m $ grep -i DAC960 /lib/modules/2.6.35.11-83.fc14.i686/modules.dep kernel/drivers/block/DAC960.ko:

I'm wrong then, the module still exists. I am too used to modules being lower case that I didn't perform an case-insensitive search.
Aaron, you should try a LiveCD or USB image and try to modprobe your module. The Disk Utility (palimpset) should display your card at that point.

Yes, Anaconda used to detect and load the DAC960 driver on FC4, but post FC4 Kudzu but does not seem to support DAC960 detection any more.

Okay, that maybe a work around, thanks,

That is good news. Thank you,

Right. As far back as 2004, I recall using the dac960 driver on redhat linux.

It should automatically load the module providing it is on the image. It could be the autoload is failing for some reason or the driver is broken, or its not on the boot image.
Unfortunately the one person who really knew it and looked after it (Leonard Zubkoff) died in an accident some years ago. It no longer really gets much attention as it's little used and IBM who bought Mylex who produced it have long dropped it too.
In fact I think you are the first reference I've seen to it in use for a couple of years !
Probably the best strategy is to investigate using a live image and see what "dmesg" shows and what occurs if you try and load it. That may give the info needed for someone to get it going.

Thanks Alan,
So possible the driver code got broken in newer kernels. I know FC4 used to use Kudzu and moving to FC5 the detection of the 960's no longer worked in Anaconda.
How does driver detection work now, is it the same for all Linux distros now ?
Like you said I'll try a live distro and dmsg anyway, and see if that reveals any more info.
Its more than a couple of years since I removed the RAID cards, the poor old Primergy 470's servers are not as fast as with the DAC960's. I would really like to get the DAC960 working again.

DAC960 works again on F14. It was still broken on F9, not sure about the gap.

Aaron,
You could try to add an "module=dac960" or "module=DAC960" in the grub kernel command line before installing fedora.
