[lug] RAID installation on Fedora 6 Zod

[steve at badcheese.com]

If Linux sees the card, then it'll just look like a SCSI disk to the OS 
and you do all of your config either in the BIOS or there might be a 
utility with the linux driver.

LSI has some good RAID controllers and you can use the linux "megamgr" 
suite to control the controller from within linux, but most of them will 
just have you do the RAID manipulation in the BIOS.
