Vista - Missing CD/DVD driver on NEW Vista Ultimate install

I am trying to install Vista Ultimate x32 on a new/formatted hard drive.
The DVD boots up, I select INSTALL NOW (at the Install Vista window) and an
error message comes up after "PLEASE WAIT..." (for several minutes) on STEP
1 Collecting Information... specifically, "A required CD/DVD drive device
driver is missing. If you have a driver floppy disk, CD, DVD or USB flash
drive, please insert it now. Note: If the Windows installation media is
in the CD/DVD drivem you can safely remove it for this step." with BROWSE,
OK and CANCEL buttons. Then the "Select the driver to installed" window
comes up asking for media (CD, DVD, USB, etc). I searched Microsoft
Support/KB site and found no hits on this problem nor solution.

At first I thought Vista wanted (similar to F6 in Windows XP setup) the ITE
RAID driver to access the hard drives (serial ATA mirror 1 raid on
motherboard controller... which I have for Vista). However, it is able to
see them when I browse for drivers... so it seems to recognize the hard
drives. There is only one DVD-RW drive installed in the system... on the
PRI IDE controller (only device on this bus)... the one from which Vista was
booted from. I tried downloading and supplying different drivers to bypass
and get past this screen... but I can't. The only option is to exit the
installation.

The DVD is a DVR-109BK. To check that the DVD-RW drive was working, I
went thru the process of a clean install of Windows XP Pro... it worked, no
problems. I checked the DVD-RW firmware... it is at the latest level...
v1.58 2005/08/09. Boot up sequence is FLOPPY, DVD, then mirrored SATA 320GB
drive.

Any ideas as to how to get the Vista install to the next step?

I don't have another DVD-R(w) drive right now... could get and try.
I did try another RETAIL Vista DVD... same problem.

I should mention... Vista Upgrade Advisor stated only issues with Audio
device and Video card (for Aero support).. as well as MSN Messenger not at
correct level for Vista. SYSTEM results showed DVD can read DVDs... as well
as DEVICES showed ITE RAID IT8212 was okay as well. Pc has 2GB RAM/320GB
hard disk, Pentium 4 at 3.0GHz.

Tried another DVD drive (DVD-R / Toshiba SDM-1502 instead of DVD-RW /
Pioneer DVR-109BK ) and absolutely NO PROBLEMS doing the install. Be
careful if using Pioneer DVR-109BK... you may run into issues with it
natively being supported under Vista installation... even if it passes the
Vista Upgrade Advisor check!

PROBLEM SOLVED!
