I thought that labels, ids, etc, did not work on grub. There is a map file that "defines" the correspondence beetween both, but I don't know which side is the "boss" side. I think it is the bios who defines them.

AIUI: 1-device.map is used by the grub shell 2-grub _shell_ is not part of normal boot process Maybe I have something about this mixed up and it is Bob S's 11.2 device map that needs fixing. Does Grub v1 actually know how to use /dev/disk* entries? I don't remember ever seeing device.map files of more than 45 or so bytes on any of my 11.2 or Factory installs, too small to be using /dev/disk* strings for mapping. Do mkinitrd or perl-Bootloader depend on correct device.map entries to function correctly?

As far as I know, grub only understands the (hdX,Y) entries. The rest are read by the kernel once it loads.

I don't know what relly uses that file. - -- Cheers, Carlos E.

I read somewhere, can't find it right now, that Grub uses it when it gets confused about something. Disk order? Dunno Bob S -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
