Mak, let me know if you ever get in the Lancaster area of Pennsylvania. I owe ya a 6 pack now.
My system is running. I got it to work via nLite. XP Pro SP3 (via new CD) and Ubuntu Hardy are both on my system on the same hard drive running in AHCI mode.
The problem was simple. I needed the storage manager driver from the ASUS web site. However, it was stored under Utilities... I was thinking the driver under SATA would be the one I needed, considering that I needed a SATA driver and all for AHCI to work.
XP is running now. The installation method I posted earlier with all of those pictures is the exact way I was supposed to do it.
Mak - Thanks a lot, as always. And I'm serious about the 6 pack.
Now, my only problem is my onboard NIC isn't supported out of the box in Ubuntu. In fact, I don't even know if it's supported at all. According to PC Wizard 2008, I have an Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller. However, it's also listed on the main page as "Attansic - now owned by Atheros". I used a 3Com wireless USB adapter to pull all of my Ubuntu updates down, but unfortunately nothing came through of use to my wired adapter.
Edit - also, do I NEED a restricted driver? Ubuntu didn't prompt me to download a restricted driver for my 9600GT.
