I did some digging on the Server 2003 forums and found that if I use the following driver Intel(R) ICH8R/ICH9R/ICH10R/DO SATA RAID Controller the OS will load.
I am looking for a driver that will allow me to load Server 2008. I have changed the BIOS setting over to RAID. I have the Intel driver that came with the Vostro 220s, but I think this is not the correct one due to the Vostro originally coming with Windows XP. Each time I try to load it I get a BSOD (STOP: 0x0000007B). Any help is appreciated. 
RAID driver for Vostro 220s that works with Server 2008
