So this is your board?

4 Sata Ports and Intel Matrix Raid Level 0 and 1?
Is there anything in the Bios where you can configure the SATA-Operation Mode?
Redhat 9 will probably not pix_II driver module loaded if it's configured as SATA-Raid. So if it's possible to change the setup change it to combined or ATA mode.
I hope that helps.
If I can ask you a question...? Why don't you use CentOS 4.3 it's a perfect Redhat Enterprise 4 clone.
