RE: Can't configure grub to use less memory

[Darren Gamble]

Good day,

Thanks for your reply.

I realize that this is documented in the manual.

I had already tried that combination, though.  It does not work.

BUT, another member of our group examined this last night.  He deduced that
the parameter passed to uppermem needs to be smaller than the amount passed
to the kernel, or initrd won't load.  After using uppermem=818176 (one meg
less), it then properly boots.

Thanks to all who helped us with this problem!  =)

A workaround for that problem is to run "uppermem" first of all, then
load a kernel and an initrd afterwards. This is clearly documented in
the manual.

Here is an example:

title Linux with less memory
uppermem 8192000                        # 800MB.
kernel /boot/vmlinuz mem=800M root=...  # Specify options appropriately.
initrd /boot/initrd

Jeremy, I don't stop you making your own patch to have GRUB to load an
initrd more elegantly, but I remember that a patch has already been
written for the Conectiva version. Thus, it might be easier to adapt
the patch to the CVS, rather than reinventing the wheel.
