Hi, I guess the tool from [URL] can help you install WXP using SAS Driver, it will integrate the driver into the OS, creating a new ISO for installation.  Their guides page will help you step by step. 
Hi I have the above titled specs, Windows server 2003 standard r2 32-bit is installed. Got it used.I have data-mining software that can take advantage 64-bit and doesn't require any server capabilities. Upgraded CPU/32GB ramChanging over to Windows XP Pro 64-bit.Installed it, had the sas 5/i drivers on a USB flash. Went through the usual process, deleted and formatted partition. XP then starts the long process of loading all its files and restarts the computer.  After the computer restarts, it just boots to Windows server 2003 again. Pulled out all but 1 drive 3 times and booted from each. Each time booting to 2003. So I realized the sas 5/i "non-raid" must be backing up to all drives (like a RAID).Then I left only 1 HDD in, booted XP, did the format and install again, it restarted, and again Server 2003 starts up.Whats the deal? Looked in the integrated controller for settings to delete drives or format them but there's no such options.
