Are you sure you've got "boot from CD" selected in the BIOS? Can you boot from other bootable CDs? Have you ever booted from CD-R(W)s before? Occasionally, the drive will take so long to detect that there's a rewritable disk in the drive that the BIOS will give up. One "solution" can be to carefully time when you insert the CD, so that the CD is still spun up when the BIOS tries booting from it. James. -- James Wilkinson | Examiner: How does an AC motor start?
