I have the ASROCK 939-DUAL running windows XP sp2. I boot from SATA1 HD's set to RAID 0. Everything was working fine until I changed an IDE setting in the BIOS. (AMI BIOS P1.20). The only IDE device I have is a lite-on CD burner.
I changed the "on board IDE controller" to Primary ( was set to BOTH)
also changed the "Primary IDE Master" to CD/DVD (was set to Auto)
also changed the "Primary IDE slave" to Not Installed (was set to Auto)

upon boot, the system BIOS hangs up (stops processing) after the memory test as follows:

Auto detecting Pri master ..ATAPI CDROM
Auto detecting 5th master ..ATAPI CDROM
Pri master: Lite-on Combo SOHO 5235K LK02
Ultra DMA Mode 2

..And then it just stops. It doesn't matter if I press F2 or not.

The code on bottom left corner says 0078

When I press F2 to get back into the BIOS setup utility, it says "Entering Setup" but it doesn't give access.

I can't get back into the BIOS setup. Please advise.
Thank you for your help.

Just clear the CMOS:
Clear CMOS Jumper (CLRTC1)
Note: CLRTC1 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short pin2 and pin3
on CLRTC1 for 5 seconds. However, please do not clear the CMOS right after
you update the BIOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system first, and then shut it down
before you do the clear-CMOS action.

I was told by some one to clear the CMOS which I have never done before. After the carry out the procedure - shorting the 2 jumpers. Do I leave them there, or revert back to their original position before the next boot-up?

You'll have to revert the jumper back to its original position.

While trying all this stuff, disconnect the data cables from the IDE drives for now (power off first) so they cannot go haywire.

Do not assume anything

System error, strike any user to continue...
