Thanks for this really useful guide. I just have one question, and I appologise if its been asked before. I only have a SATA optical drive + 2 x SATA hard disks (with an additional e-sata port). My chipset is intel 975 (shuttle sd37p2 barebones). I can't find any information on Jmicron ports in the manual. Will I be able to install windows with from my optical drive using SATA AHCI mode (no IDE) set in the BIOS? I can't think what other options I have, because i have no floppy drive. I could arrange to borrow an IDE optical drive, but that would only be temporary. In this case, could i simply operate the BIOS in 'enhanced mode' (sata + IDE) for installation, and then switch to "SATA-only" once XP is installed?
