I'm trying to get the RHEL-5 version of their kernel driver to install with no luck so far.
http://www.adaptec.com/en-US/support/scsi/u320/ASC-39320A-R/
Here is what I'm seeing when I install their provided .RPM:
[root@hcnas ~]# rpm -i a320raid.rhel5.i686.rpm
Adaptec adp94xx driver installer - V1.2.5934.0-1
Backing up all modified files to /boot/adp94xx-backup-4
Using GRUB configuration If this is not what you want, rename your /boot/grub/grub.conf file /boot -rw------- 1 root root 2403318 Jul 27 07:39 initrd-2.6.18-8.el5.img
/boot/vmlinuz-2.6.18-8.el5 /boot/initrd-2.6.18-8.el5.img CentOS (2.6.18-8.el5) Configuration [CentOS (2.6.18-8.el5)] /boot/vmlinuz-2.6.18-8.el5 -> 2.6.18-8.el5
