The vendor who built the server confirmed that the controller card
should be LSI 1068E.

I found a driver for RHEL5.5 from LSI's page. And some more digging
revealed that I should be able to use linux dd=url format for loading
the driver from network as the machine has no floppy. I will test that
next week when I get my hands on that machine again.

A few questions though I would like to get answered:

1) What is the best way to find out if a certain controller etc is
supported by the kernel? Do I need to download the kernel src rpm,
install it and look for some documentation/source somewhere?

2) If I need to use the binary driver by LSI, how do I proceed with
kernel updates?

Best regards,
