Hi,
I have to install this server with an Intel motherboard ASUS, model P5VDC-MX.
It has a VIA hardware RAID controller model VT-8251.
The two hard drives are SATA (don't know if II) and are Maxtor STM380211AS.
Problem is that CentOS installation doesn't recognize any hard drives at all.
The BIOS setup doesn't have an option to turn off SATA.
Any ideas ?
Thanks in advance.

So far it looks, to me, like an issue at the bios. Check to see if one of your sata drives is registered in the bios as bootable. Some times you need to reboot ( after making bios changes ) in order for the drive to be found.

They'd like you to think that, and their marketing team works hard at pushing this belief. What you've got there is considered FAKERAID. Mostly they put software raid on a chip and farm out all the work to the CPU. At most you can use these to connect extra disks to the system. At worst, they'll get in the way and prevent installs. It's along the same line as the 'winmodems' or software modems that everyone was touting before cable and DSL was cool.

Far as I know, support for this chipset didn't make it into the kernel til around 2.6.17 or so. It *might* be supported in centos5 (you can try the beta if you like) but I don't believe it's supported for centos4, on the 2.6.9-* kernel versions.

Ignore that controller and get yourself a 3ware card?

Or get one of the relatively cheap Silicon Image based SATA cards. I believe those have been supported "out of the box" long enough that 4.4 will find your disks without any additional hassle.
Cheers,
Be careful with the Sil chips, some of them will not support certain HDD's at the HW level. I had a problem with Maxtor DiamondMax10 300GB SATA150 disks. My Sil controller would not support staggered spin up and the drives simply wouldn't power on.
3Ware are very reliable.

You're definitely preaching to the choir about 3Ware. :) Just trying to offer an alternative. I hadn't heard about those types of problems with the SiL-based cards.
