Bug#588293: grub-pc: fails to allocate memory so nothing can be booted (on an old compaq

[Roland Kletzing]

Hello,
i have the same problem that after Debian 6 installation on an older 
mini-pc, the system does not come up but i´m getting "error: cannot allocate 
real mode pages".

After hours of searching/fiddling i found this is a grub issue and resolved 
with grub 1.99, but i`m wondering

1. How i do a clean upgrade to grub 1.99 at installation time ? What is the 
straightforward way to proceed with that?
2. Any reason, why 6.0.4 still comes with older/broken grub 1.98? Will 6.0.5 
have grub 1.99 ? So i would probably wait before installing the other 
(identical) systems.

regards
Roland

ps:
I`m relatively new to debian and this is my first bugreport, so sorry if 
something is not correct.
