RE: Process not given >890MB on a 4MB machine ?????????

Hello again,
And thanks,

	>UltraSPARC or MIPS) 

I hope (fingers crossed) that there is some way around this 
I think that Redhat  now supports up to 64GB of ram, 
as the Xeon has 36 address lines, see attached.

I'm only grasping at straws here, but I hope that it is somehow possible 
on this machine?

Pentium(R) III Xeon(tm) processors 
Extended Server Memory Architecture
Full 36-bit addressing allows enterprise applications to transcend 
the traditional 4GB (32-bit) memory barrier by adding 4-additional address
bits. 
PSE36 (Page size extensions) adds 4 additional address lines to the current
32 bit address. 
As each bit is added, the cacheability range doubles: 
32 bits= 4 GB 
32 + 1  	= 8 GB 
32 + 1 + 1 = 16 GB 
32 + 1 + 1 + 1 = 32
32 + 1 + 1 + 1 + 1  = 64 GB 	

	The additional headroom allows: 
	Greater than 4-gigabytes of cacheable system memory
