PE800 SATA detection under opensuse 10.2

[Mathias Wagner]

Hi,

I have recently updated our Poweredge 800 to opensuse 10.2 (kernel 2.6.18 
series). Previously it ran under Suse 9.3 (kernel 2.6.11).

I have two sata disks attached to the on-board sata ports. With the old 
installation both disks were recognized, but with the new installation only 
the first disk is recognized. I also tried attaching a different sata disk.

The SATA controller is set to "ATA", since it do not want to use the RAID of 
the ICH6. 

Under Suse 9.3 the disk were configured as software RAID, no this obviously 
does not work anymore. (RAID runs with one disk).

It think the problem is somehow realted to the ICH6 and it's settings (I don't 
know all the details but I believe it can work also in some PATA compatibilty 
mode.) But I am not quite sure about the BIOS settings and what mode is set 
when using "SATA".

Does anyone know this problem (and a solution) ?
