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. -- :wq! M?rio Gamito

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.

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.> Problem is that CentOS installation doesn't recognize any hard drives at > all.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.> The BIOS setup doesn't have an option to turn off SATA. > > Any ideas ?Ignore that controller and get yourself a 3ware card? -- During times of universal deceit, telling the truth becomes a revolutionary act.
