It's difficult to figure out how to configure Xfce to use the soundcard workaround (a usb sound card device) that was the solution for Win2000. However, since Mint has revived the sound card, this isn't a problem.
Dual-boot with Win2000 isn't working, but this may be due to the hardware setup. I ended up switching the hard drives around to get Mint to boot, but even after an update-grub and several attempts at manual settings, it won't boot Windows. It will read/write on both hard drives, but I think the BIOS may be causing it to fail to boot from the secondary hard drive. I might tinker with the jumper settings next.
