G'day all. I'm moderately experienced in Linux, but I'm having a bizarre but completely reproducible problem. I have installed openSUSE 10.1 and Windows XP Pro on a Clevo M570U laptop – several times. And every time that I do, the Philips DVD Burner becomes invisible to Windows. - not appearing in the Explorer list, the system hardware list in device manager, etc. It's as though it's been physically removed from the computer. I have twice installed Windows then SUSE, and the DVD is OK until SUSE is installed. I once reinstalled Windows afterwards, and the DVD was OK until I booted into the SUSE install and re-installed GRUB. The DVD works fine under SUSE. The grub.conf file is as follows: --------------------------------------- root (hd0,1) install --stage2=/boot/grub/stage2 /grub/stage1 (hd0,1) /grub/stage2 0x8000 (hd0,1)/grub/menu.lst install --stage2=/boot/grub/stage2 /grub/stage1 (hd0) /grub/stage2 0x8000 (hd0,1)/grub/menu.lst quit The menu.lst file is as follows: --------------------------------------- # Modified by YaST2.
