This is the OS Elastix is using:

~]# uname -a
Linux OpsiPBX1 2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:22:04 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

Is this supported (see above link): - Red Hat Enterprise Linux 5 Update 5 (x86)

It differs after the -238
also its 64bit...

I believe its supported however:
Even with linux dd It doesn't prompt to load the driver disk...as per below steps in link:
5. Boot server with Linux bootable dvd and on boot prompt give command boot : linux dd
6. Next it will prompt for driver path so provide USB stick path. This will install drivers for RAID controller.

Solved it ...USB with driver had to be in at boot time.
shaunwinginAuthor Commented:
However now gives error after loading driver:
elastix unable to download kickstart file after load driver disk
has location as cdrom but it can't seem to read it...
It seems a common error
pls help....

First your question is not clear to me at least.  It sounds like you are trying to configure a hardware RAID.  It is not done from BIOS, it is the hardware RAID utility.  In your case, it will be HP's hardware RAID utility that you need to use and after that you should be able to see that new device.  So make sure you are using the utility correctly and saving your changes.  I have had such problems when for some reason the utility did not work correctly.

See the link above and repeated below
I'm simply following these instructions, but have an issue -see another post:
I tried these links, they are not showing me anything useful.

At the boot, you should see option for BIOS and after that you should also see option to enter the hardware RAID controller's interface.  I forgot the key strokes, but it is simple.  Enter that option and then you should first delete any existing raid then choose both of your devices and make the raid you want and then just follow the instructions.  Before exiting, you should be able to see that device that you just created.

The Raid part is going through 100% its rather an issue with the driver stage...
Look !!!

If you have done with RAID configuration in system then i suggest to boot up the system with linux dd and then once installation is done you need to redesign the disk arch in order to function the meta device otherwise /dev/sda will be usable only and another disks will be idle. Then follow below steps.

press CTRL+ALT+F2
cp -a /tmp/ramfs/DD-0 /mnt/sysimage/tmp
chroot /mnt/sysimage
cd /tmp/DD-0
sh ./fix_driver_order
cd /
press CTRL+ALT+F6 and click reboot

NOTE: i prefer using the FDD instead of CD rom for this purpose.
