Description of problem:
----------------------

I have installed Linux Red Hat Advanced Server 2.1 on a Dell Optiplex 
GX280 with a SATA/150 Maxtor Hard drive 6Y080MO but I have some boot 
problems.

I couldn't start the installation because of two "PCI-IDE: unknown 
IDE Controller" error messages.

Then in the BIOS I changed the "SATA Operation" configuration 
from "Normal" (default) to "Combination": this causes one of two 
error messages to disappear and I could install Red Hat.

Now Linux is installed but I can boot only in single user mode, 
otherwise during the boot I have a 
"PCI_IDE: unknown IDE controller on PCI bus 00 device fa, VID=8086, 
DID=2651" error message.

In the /etc/sysconfig/hwconf I have several "unknown" entries and on 
of them has VID=8086 and DID=2651.

Is there any patch I can install?

I only can use RHAS 2.1: I need to install on it an application that 
is only certificated with RHAS 2.1
