You should do your homework now, and make a proper effort at

Is there a sure-fire way to know the right 'root (hdx,0)' invocation
when you are installing grub on the 2nd disk of a raid1 pair when you
expect the drive id to shift in case the primary drive dies (scsi) or
when you don't (ide)? Of course in the IDE case many failure modes
will make the machine not boot until you remove the dead one, in
which case you might as well shift it to the primary position anyway,
and you'd still like it to boot.
I think grub pretty much follows the BIOS.
All this talk about grub reminds me of something I wanted to do a few
years ago and never quite succeeded, so maybe someone else will know how.
I'd like to have a locally installed system, but have one of the boot
choices be to network-boot into an LTSP thin-client. I don't want to
just PXE boot because I want the default after a timeout to be a local
OS. I thought some versions of grub used to be able to do the
equivalent of an etherboot internally, but that may be gone now. If I
have a stand-alone bootable floppy or CD that will network-boot the way
I want, is there a way to copy that to the hard drive and make a grub
menu choice that will load it?
Hi Les,
If I understand you correctly that sounds like my setup. I use pxeboot
with a tree'd menu. Sub menus are boot, install, and tools. If nothing
on the main menu is selected within the timeout period the connecting
machine is instructed to boot locally using its own grub loader.
Here is the top level menu (/tftpboot/pxeboot.cfg/default)
DEFAULT menu.c32
TIMEOUT 100
ONTIMEOUT local
MENU TITLE Main Menu
LABEL local
MENU LABEL Boot from ^Local Drive
LOCALBOOT 0
LABEL boot
MENU LABEL ^Boot
KERNEL menu.c32
APPEND pxelinux.cfg/boot
LABEL install
MENU LABEL ^Install
KERNEL menu.c32
APPEND pxelinux.cfg/install
LABEL tools
MENU LABEL ^Tools
KERNEL menu.c32
APPEND pxelinux.cfg/tools
If you want the submenus, too, let me know.
Mike Wright :m)
