I just installed this on an older Epox 8KHA+. After my bios update to support 48bit LBA (you already ahve this) I installed winxp to a 40 gig partition since pre SP1 won't detect more than 136gigs. Once you install, put sp1 on right away, then you can extend the partition to whatever size you want using winxp's volume manager. Mine is using the full drive.
