We have Suse 9.2 installed on dual bood amd64 system. This has a SATA drive, /dev/sda. A few days after installation, we added a second drive, and IDE drive, dev/hdd. Suse recognized the drive, I mapped it to /windows/DOS. This all works fine. The only guy here who wants to use dos wants to be able to boot dos from the second drive without going into the BIOS and setting the boot order. I have modified the GRUB list etc via YAST and added the following. Disk order /dev/sda, /dev/hdd title MSDOS 6.22 map (hd0) (hd1) map (hd1) (hd0) makeactive rootnoverify (hd1,0) chainloader +1 When you boot from grub and select MSDOS, you get a flash, then back to grub. It is too fast to read what is on the screen. I changed the listing to title MSDOS 6.22 unhide (hd1,0) hide (hd0,0) makeactive rootnoverify (hd1,0) chainloader +1 When I boot and select MSDOS, I know get an error 12: invalid device. Would appreciate any help or a link to where I could get more info on this. Art
