Machines like this require a special SMP HAL to get them to work.  You could 
try the experimental kernels from http://www.hansenpartnership.com/voyager  
which contain the SMP HAL for the voyager systems (which is what a 3525 is).

BIGMEM kernel question

[Eric Anderson]

I am currently running a RedHat 7.1 machine with the 2.4.3-12enterprise
kernel.  My machine has 4GB of RAM, and 6GB of swap.  It appears that I
can only allocate 2930 MB (using heapc_linux and other programs).  What
do I need to do to get Linux to allow allocation of all available memory
(up to the 4GB)?  All the FAQs I have seen so far explain only how to
get Linux to recognize the 4GB, and not use it all in one process.  Any
help would be greatly appreciated.

Please CC this email address in any responses.

Thanks!
