I tried installing again, specifying "mem=2G", and it zipped right along. Now
I have a working machine that runs fine as long as I specify a "mem=" amount.
However, having specified "mem=4024M" in my grub.conf, I
actually ended up with this:
[frankcox@mutt ~]$ free
total used free shared buffers cached
Mem: 3342416 702628 2639788 0 16480 289760
-/+ buffers/cache: 396388 2946028
Swap: 2031608 0 2031608
I have more ram now than I did with "mem=2G" but I seem to have lost 760mb;
4024-3264=760.

How would I go about making these adjustments and what adjustments should I be
making? (I know absolutely nothing about MTRR.)
Here is what I've got now:
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg02: base=0xc0000000 (3072MB), size= 256MB: write-back, count=1
reg03: base=0xcf800000 (3320MB), size= 8MB: uncachable, count=1
reg04: base=0xcf400000 (3316MB), size= 4MB: uncachable, count=1
reg05: base=0x100000000 (4096MB), size= 512MB: write-back, count=1
reg06: base=0x120000000 (4608MB), size= 128MB: write-back, count=1
reg07: base=0xd0000000 (3328MB), size= 256MB: write-combining, count=1
What changes should I be looking at making, and how do I go about making them?
(Thanks ever so much for your patience and assistance. I'm really 100% lost
with this matter at the moment and would love to get a better understanding of
how all of this works as well as make my new computer use all of its ram. In
other words, I'm interested in "why" as well as "how", if possible.)
