I mention this here since people often ask for it. I found that it is possible to use the CD booting feature of smb from the GRUB prompt with the help of memdisk. I'm using GRUB 0.93, incidentally.
SBM, the Smart Boot Manager, is available at http://btmgr.sourceforge.net/ and allows you to boot from a CD or DVD even on machines whose BIOS does not support this. Of course, you do need a CD or DVD drive respectively. Memdisk is part of the SysLinux project at http://syslinux.zytor.com/. Long ago support was added to GRUB to allow using memdisk as a 'linux kernel' to boot a virtual floppy; in the present case I use this in my menu.lst file: # CD-ROM via Smart Boot Manager title Boot CD-ROM or DVD kernel (hd0,0)/image/memdisk initrd (hd0,0)/image/sbm.bin as memdisk and sbm.bin are about 14 and 18 kb in size respectively, they can live on the disk without using up a lot of resources. Selecting this from the menu boots a CD or DVD in the drive. Copies of the memdisk and sbm.bin I am using are available at ftp://ftp.mcc.ac.uk/beta/local/teaching_cluster/disks/ . The use of SBM is a bit awkward, but it stops people from changing the BIOS to allow CD-ROM boot and forgetting to put it back. The menu from which the above entry is accessible is password-protected. -- Owen [EMAIL PROTECTED] _______________________________________________ Bug-grub mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-grub
