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.
update the BIOS to the latest, make sure you do a CMOS reset to
defaults, and turn ACPI back on and try again.....
ahhh after I wrote that previous line, I googled `linux dq35jo` and
found http://kbase.redhat.com/faq/FAQ_103_11855.shtm about 5 hits down.
Issue:
Why does my Intel DQ35JO or DQ35MP-based system not boot when
I try to perform the initial installation of Red Hat Enterprise Linux 5.1?
Resolution:
The Intel DQ35JO and DQ35MP systems require the specific boot parameter
pci=nommconf
to boot during the initial installation of Red Hat Enterprise Linux 5.1
(RHEL5.1).
The parameter is not needed after installation.
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

What does it means and how can i fix this?
turn that fake raid crap off, and use linux software raid instead.
Anaconda makes combining linux raid mirroring and LVM a bit tricky at
setup time, but it -can- be done. custom disk partitioning, delete all
partitions, create a 120MB /boot on both drives, create a raid1 mirror
on the rest of the two drives, then create LVM partition(s) as / (and
/var,/home, whatever if you want several seperate file systems, your
choice) in that raid metadisk, and install to that.
