First ... a dd image is used to do an image WHILE installing RH or CentOS. You need a different image for normal operations. Is this during an install of CentOS, or are you adding it to an already running server?

Second ... Precompiled drivers are for a specific kernel version, and if you want to use the precompiled driver, you need to use the kernel it was built for. CentOS kernels WILL USE drivers compiled for RHEL AS IS.

I tried looking up that card on the internet, but could find no drivers or website that was in English.

Duel,

In reverse order:

1) The 3ware 9500 and 9550 sata raid controllers work with Centos 4.2 out of the box.

2) If you can find the source code for the Pacific Digital QM-4300R10 driver that has been used in Centos 4.0 it might, "might" compile properly on a single disk 4.2 system.

You would then need to build a driver install floppy to get the drivers for a Pacific Digital QM-4300R10 that are needed during 4.2 install.

A detailed explanation of how to build an install driver disk is in the knowledge base on 3ware's web site.

You should contact Pacific Digital and see if they have an install disk for RHEL 4.2.

It might work on Centos 4.2.

Best of Luck,
