Everyone,
Thanks for everyone's comments.
To make things as clear as I can this is a DELL XPS Gen 2 Series a 32
bit machine using an i386 Centos OS 5.2 that was automatically upgraded
to 5.3 by yum.
The RAID controller appears to be on the mother board to me. The CPU is
an Intel Pentium 4 3.00GHz. BIOS version of A02.
In the bios I can turn on RAID on but when the system boots I get a grub
prompt. The only way to get the system to boot is to turn off the RAID
configuration and boot to one drive.
I have not seen anything regarding PERC. The SATA drives are connected
directly to the motherboard.
I have still not been able to make it work as RAID.
Thanks to everyone for your help. This is my first RAID controller.
Greg
