with a fix from the manufacturers. The other alternative seems to be the
mem=xxx option passed to the kernel. If I use the latter approach, is
this something that I can develop a script to do automatically at boot
(for example, to run it as part of the GRUB parameters), or is it
something that I would have to do manually?
$ grep kopt /boot/grub/menu.lst
## If you want special options for specific kernels use kopt_x_y_z
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=/dev/hda2 ro vga=791
# xenkopt=console=tty0

Thanks for this Andrei. How would I tweak this to enable my kernel to
recognise and utilise the additional RAM? Looking through the file, the
relevant section appears to be this commented part:
No, the line you need to edit is the one with 'kopt=...'. Don't
uncomment it, just add the relevant parameter to the end (like I added
vga=791 for my laptop).
After you're done you *must* run /usr/sbin/update-grub

My question is about the specifics of the option to add at the end of
the line:
Because I am looking for 2GB RAM to be recognised, do I add mem=2097152M
to the end of the kopt=... line? I don't, for example, know what outcome
you were looking for and resolved by adding vga=791 to that line in your
config. VGA I can but assume had something to do with a graphics card,
but beyond that ... ?
Thanks and apologies for being apparently dense. I can assure you I'm
not being deliberately obtuse.
