grub and memory access

[Rob White]

Sorry to ask such a trivial question, but, can grub limit the ammount of 
memory accessed by an os that it is booting?  The scenerio is that I 
multiboot redhat 7.2 an two flavors of windows using grub.  I have 1 gig 
of ram.  Windows 98 has lots of memory accessing issues if you have more 
than 512 megs of ram installed.  If at all possable I'd like to tell the 
win 98 boot that there is only 512 megs of ram, but I don't know how or 
if it's possable to restrict memory access with grub.  I'm using 2 512 
meg blades in slots 1 and 2.

Thanks, and sorry for the stupid question.
