I have recently purchased an MSI 865PE platinum board (ICH5R chipset)with amongst others a 300Gb SATA drive. On trying to load XP, the install fails after loading the initial driver files with a DMBOOT.SYS is corrupt message - doesn't get as far as inital install/repair screen. The CD itself is fine as it boots on other machines. BIOS is set exactly as per MSI manual. Any ideas - I am baffled...thanx
