I've been trying to use memdisk with grub2 to boot some iso images -(
I've done this without any
problem with pxe )
There is a memdisk.mod in /boot/grub/ and I've seen some material talking
about this, but no example
of a menu.
After trying countless permutations - Right now I have :
menuentry "Memtest-Plus 4.2" {
echo `hello`
insmod lvm
insmod part_msdos
insmod jfs
insmod memdisk iso
set root='(ssd-testing)'
search --no-floppy --fs-uuid --set f9ae292b-b6a9-4f70-af7c-31987e766d37
# echo 'Loading memtest-Plus'
linux16 memdisk
initrd16 memtest-plus/memtest86+-4.20.iso
# echo 'Loading initial ramdisk...'
}
I've done a lot of google searches and even downloaded the source trying to
get a glimmer of the
syntax - so far with out joy...
I've verified the set root and lvm part is right with normal boot setups..
I tried putting a copy of memdisk in /boot/
If anyone has a 40_custom file that boots iso using in memdisk.mod - please post
it. Everything I
find is for grub1..

Everything I find is for grub1..MEMDISK is a "kernel" and the 'iso' parameter (being a MEMDISK parameter for booting .ISOs) belongs in the "kernel command line." I have no clue what the point of 'memdisk.mod' would be; maybe you don't need it. - Shao
And when I searched in Google with: "memdisk.mod" grub This was one of the search results: http://lists.gnu.org/archive/html/help-grub/2011-02/msg00020.html which appears to answer your question (hopefully) and confirm my last response. - Shao Miller
