Asus P4V8X-X motherboard and Mylex AcceleRAID 170 PCI to Ultra 160 SCSI Raid Controler

Hi,

I have a brand new Asus P4V8X-X motherboard.  I use a Mylex AcceleRAID 170 PCI to Ultra 160 SCSI Raid Controler (Bios V 6.01-30) on which is installed Windows XP Professional.

The Problem that I am having is this: My PC keeps trying to boot to one of my IDE hard drives instead of the Raid.  I keep ssetting the motherboard Bios to boot to the Raid and it has no problem recognising the Raid.  However, 50% of the time it re-writes the bios back to using the IDE as the boot device and I have to re-edit the bios and save to re-boot the PC.

Any help please?

Have you tried changing the CMOS battery?  Erratic behavior means the setting is not holding.

Well, as I said, the board is brand new, I only bought it about 2 weeks ago.
Batteries are cheap, couldn't hurt to try.  It's possible a bad battery was put in.  Or if it sat on the shelf for a while at the store..
I would download the latest mobo bios and flash it. Make sure you have set the BIOS to non-pnp OS (avoids OS overriding settings).  
I have an ASUS P4c800 board with the built in RAID option but just running IDE. It's was my understanding that if you choose the RAID configuration the IDE must be disconnected. Do you have a IDE hard drive connected as well?
If your mobo supports boot order and identifies the RAID as a boot device it should not matter what you have connected, it is supposed to boot in the order you specify in BIOS. There are some really junky raid cards out there, so....

Are your CPU settings resting also /?
Can someone interpret what that accepted answer means?
I'll second that question?  I would be curious to know what exactly had to be done to fix the issue.  :)
He posted a note saying that he accepted the wrong answer, and that he meant to accept sciwriter's answer.  A correction should be coming, but it's still not quite what I would call a solution.  There are a number of BIOS'es that allow you to choose the boot device, IDE and SCSI being among the choices.
