[CentOS] Centos 4 and Supermicro ICH7R

Hi:

I've tried to install centos 4.3 in a raid array, setuped on bios as mode "Adaptec". The chip is ICH7R but centos always sees 2 drives instead of the array that I create. I've contacted Supermicro support and they gave me this link ftp://ftp.supermicro.com/driver/SATA/Adaptec_ICH7R/Linux/Redhat/ , but the disk drivers I tried to use with centos 4.3 did not work, saying that the disk did not containt appropriate drivers for the hardware.

Have anyone here had similar problems? does centos 4.4 solves this issue?

I really need to install centos as an array... and as hardware RAID and not software RAID.

Best Regards, Ricardo
