OK,
this is the link you PMed to me. It lists three links, one of which is a
README for the Qlogic Fibre Channel Linux Driver for 2.6 Linux Kernels. I assume these are the instructions you are referring to.
I see that it says they only support some specific kernels, but big vendors always do that so they have an excuse. If it works with those versions, there's a good chance it will work with others.
How far did you get?
Steps 1, 2, and 3 are nothing. In step 4, were you able to make a
BIOS update diskette from the website and boot it?
In step 5, were you able to download the
Fibre Channel Expansion Card driver source code for Linux to a floppy? And the
IBM FAStT_MSJ for Linux to your harddisk?
The
rpm commands in step 6 can be done literally, although with Mandriva it's easier to use
urpmi to install things, e.g. "urpmi kernel-source-2.6.8.1mdk". And there is no kernel-headers RPM, so ignore that. Try these commands (from the instructions) to see what you do and don't have installed. These don't change anything--they just query your PC.
Code:
# rpm -qa | grep kernel
# rpm -qa | grep ncurses
BTW, it's easier to answer specific questions than general ones, and more people are likely to give an answer.
