I had problems with acessing my 4 40 GB IBM 60 GXP HD on the Promise Fasttrack 100 TX2 RAID controller.
I downloaded the fasttrack partial source 1.03.0.2 from www.promise.com
and compiled it as described in the readme. It works fine.

But for compiling the source you need also the kernel sources, etc.
Since the compiled module for Knoppix 3.3 is zipped only about 56KB I can e-mail it to everyone interested.

With the module 'FastTrack.o' available, copy it to a floppy disk
and reboot.
boot knoppix with following parameters:
knoppix dma modules-disk ide2=0 ide3=0 ide4=0 ide5=0 ide6=0 ide7=0 ide8=0 ide9=0
the kernel will ask you later for the modules-disk and the driver to load.

if you have a hd-installation of knoppix you should add the module to your initrd and add the boot parameters ide2=0 ide3=0 ide4=0 ide5=0 ide6=0 ide7=0 ide8=0 ide9=0 to your lilo.conf
