[CentOS] CentOS 5.1 on intel DQ35JO , Q35 chipsed based board

Hi,
i was trying to install CentOS 5.1 on new machine based on Intel Q35 desktop
board, witch 2 SATA disks (configured as RAID 1) , 8GB RAM and Intel Core2
QUADCORE.
The first problem was with install - it hangs before installer startup at
ACPI messages. So i installed it with ACPI=off switch.

The first problem is :
Dec  7 09:54:01 vmhost1 kernel: BIOS bug, no explicit IRQ entries, using
default mptable. (tell your hw vendor)
Dec  7 09:54:01 vmhost1 kernel: Processors: 1
Which kernel should i use? I have default installed kernel.


The second problem is with LVM (probably raid on board - in bios i switched
in sata mode to raid, and created in raid utility RAID1 volume from those 2
disks:

  /dev/sdb1                [      101.94 MB]
  Found duplicate PV hpGVb3U5Q0lxFe1LN6eJpSCJSWs0xfpu: using /dev/sdb2 not
/dev/sda2
  /dev/sdb2                [      297.99 GB] LVM physical volume
[root at vmhost1 archive]#
What does it means and how can i fix this?

Thanks a lot

David Hlacik
