Unable to Partition HD during Installation

[Wayne]

I am having a little bit of trouble installing ubuntu "Warty" I'm using 
the RC which has been installed with out problem on other computers.  
The problem starts when I need to start partitioning the HD. I asks me 
to pick a RAID device and when I select either option (RAID1 RAID 0) it 
cant find any and it keeps going in a loop.
I have tried getting help in the ubuntuforums.org 
(http://www.ubuntuforums.org/showthread.php?t=4422) and was unable to 
solve to problem there I checked google and I am still unable to get it 
installed. Would grabbing the Warty release CD be of benefit or is it 
the same installer that is on the release candidate. Here are some 
settings I have tried.

My Specs are:
p4 2.8 ghz
optorite dvd burner
intel grantsdale 915p
Intel IDE controller 82801fb Ultra ATA storage controllers-2651

BIOS Settings
On Chip SATA Mode [Auto]
xPATA IDE Set to CH.0 Master/Slave
SATA Port 0/2 Set to CH.2 Master/Slave
SATA Port 1/3 Disabled
# dmesg | grep ide
ide: Assuming 33mhz system bus speed for PIO; overide with idebus=xx
ide0: I/0 resource 0x1F0-01F7 not free.
ide0: Ports already in use skipping probe
ide1: at 0x170-0x177 on IRQ 15

# dmesg | grep hd
hdc: OPTORITE RW DD0405, ATAPI CD/DVD-ROM drive
hdc: ATAPI 40x DVD-ROM DVD-R CD-R/RW drive 2048 KB cache

BIOS settings
On Chip SATA Mode [Enhanced]
xPATA IDE Set To CH.0 Master/Slave
SATA Port 0/2 Set to CH.2 Master/Slave
SATA Port 1/3 Set to CH.3 Master/Slave

# dmesg | grep hd
ide0: BM-DMA at 0fx000-0f007, BIOS Settings : hda: DMA hdb: pio
ide1: BM-DMA at 0fx008-0f00f, BIOS Settings :hdc: pio hdd: pio
hda ATAPI 40x DVD-ROM DVD-R CD-R/RW drive 2048 KB cache UDMA (33)

and neither settings work any help would be great. Thanks for your time
