Re: [grub #67] [PATCH] ISO9660 filesystem support

[Nino Dehne]

Hello,

pardon my ignorance but is this patch only useful to have GRUB on a CD?

I have the following setup

   Intel Pro/100 S with PXE -> pxegrub
                                       \
           or                           > (nd)/grub/<machine>.conf
                                       /
   Floppy with Etherboot    -> nbgrub
   in VMware/real machine

i.e. a DHCP+TFTP server to hand out nbgrub/pxegrub and the config files 
based on MAC addresses.

now, for some machines the config file contains

   title local: boot from floppy
   rootnoverify (fd0)
   chainloader +1

which works quite well for booting floppies. Now I was under the 
impression that, given your patch, I could do something along the lines of

   title local: boot from CD-ROM
   rootnoverify (cd0)
   chainloader +1

or similar (I made up the rootnoverify and chainloader lines). I hope 
you get the idea. Is this not what your patch does? A quick test 
indicates that this in fact the case. I recompiled grub, put nbgrub and 
pxegrub on the tftp server and tried booting. Then I tried 'rootnoverify 
(' and pressed TAB to see available devices without any indication of a 
CD-ROM.

I didn't try to install grub on any disk locally, however, but there's 
another thing coming to mind: is it possible that the iso9660 support is 
only missing from the netboot files and it would indeed work as i 
described above if I put grub on a disk locally?

Thanks in advance and regards,
