I just bought an Asus P5AD2 Premium.

Is this motherboard supposed to only boot from the PRI_IDE1 primary master
HD?

When I plug a single IDE HD into PRI_IDE1, it shows up correctly (btw, all
jumpers on all IDE devices mentioned are set appropriately). When I add a
slave drive to the ribbon, the primary HD moves to the slave position and no
drive at all shows up as primary master. So when there's only one device on
the ribbon, the jumper position to determine master/slave work as expected.
When there are two devices, primary master does not appear, only primary
slave.

When I have a single HD on the PRI_IDE1, and add a DVD-RW to the ITE8212F
(PRI_RAID1 or SEC_RAID1), it doesn't show up in the bios, nor does F8 at
boot-time show it in the boot device list (it only shows the HD on the
PRI_IDE1 master.

I'm wondering if I have a dead mobo here, or should I to expect a $400
motherboard to be able to only boot from the primary IDE port's Master
device??
 
I'd double and triple check my jumper setting on the HDDs. Don't use "Cable
Select", but use dedicated "master" and "slave" positions for your two HDDs.
Then lastly I'd use another Ribbon cable or even try one of the new round
cables. Also try both HDDs, stand-alone...one at a time, as masters just to
be sure they will work correctly in that positions...using that second
ribbon cable (or round).

PS I don't know the P5AD2 personally, but most modern Mobo's will allow,
within the BOIS SETTINGS, one to select which device/order to boot from,
PLUS if you have multiple devices in any of those categories, also to select
with ONE of those devices to boot from. As and example if you had 2 CD/DVD
drives and 3 HDDs in your computer, you could select to boot First from
CD/DVDs and Second from HDDs...then you would enter the CD/DVD selection and
pick which CD/DVD to use followed by selecting which HDD to boot from if
there was nothing in the CD/DVD Drive when you booted. This is NOT a normal
boot order...just an example. Normally after everything is set up, boot
first from HDD, second from CD/DVD and third from either floppy or other
device. Some people will select a second HDD as their second boot
device...but I've never figured out the logic behind that choice. I put
multiple OS's on just different partitions on the same physical HDD.
 
Thanks for the info. I've moved to even more basics - just a single primary
master DVDRW on PRI_IDE1. Read on.

I thought I'd see if a bios upgrade would make a difference. It did, only,
for the worse. Now, after flashing to 1008, the Asus Post Reporter states
"System Failed due to overclocking" and powers down after a few seconds.

After the flash, I did clear the cmos both ways (by loading setup defaults,
and by removing the battery and moving the RTC cmos jumpers to 'clear' it).
Even at bios defaults, it acts this way.

For the few seconds it stays on, I was able to get to the hardware monitor
section of the bios, and now see the cpu temperature climbing up to 80c. No
idea what's going on there. After seeing that, I removed the cpu and cpu fan
(thinking they might not be seated correctly), heard the post reporter say
there's no cpu installed. Then reinstalled it, and same thing, no
difference.
 
ASUS tech support told me the temp increases from version 1004 to
version 1008 are normal. I think that is crazy! My CPU temps went up
20 degrees celsius at idle. I get the same overclock failed messages
and the asus ai-booster program sayd division by zero error. I went
back to version 1004 and no problems.
