Hi Marti:

I'm using a standard kernel and I get my 2Gb of RAM:

[root at squid root]# uname -a
Linux squid 2.4.20-18.9 #1 Thu May 29 07:08:16 EDT 2003 i686 i686 i386
GNU/Linux
[root at squid root]# free
             total       used       free     shared    buffers     cached
Mem:        255252     251720       3532          0      88352      88468
-/+ buffers/cache:      74900     180352
Swap:       522104      15400     506704
[root at squid root]#

First check your BIOS 'OS Install Mode' setting, if turned on BIOS limits
RAM to 1GB.

HTH
