To install software raid, first, become root:
Next, the create md device:
# mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sda /dev/sdb
Now format the device and mount it:
# mkfs.ext3 /dev/md0
# mount /dev/md0 /mnt/myraid
Finally, edit /etc/mdadm.conf and add
save and exit and type
# mdadm --detail --scan >> /etc/mdadm.conf
Check out the man pages for mdadm and mdadm for more details and options.
This should setup software RAID for you. You might want to check your Motherboard documentation. Most new MBs will mirror or stripe SATA Drives at the hardware level. Your stripped SATA drives will look like one big /dev/sda device to LInux. Alternatively, you could use LVM to accomplish the same thing as software RAID.
Please note that your device names and mount points may vary depending on what is in your needs and system. Also, make sure there is nothing on your SATA drives you want. This is a destructive process and all data on them will be lost. Back it up if you want it.

It is gentoo specific, but the similar enough to FC5 that you could make due with it.

But it is old and mainly deals with Raidtools and 2.4 kernel distros. I'd only use it for a history of software RAID on Linux.
Good luck and remember, Man pages are your best friend. Google and forums are your second best friends.
