64 bit xp

[Drew]

I am having a problem getting xp to see all 4 gigs of ram on windows xp 64
bit.... I still am not finding the right answer after much research... I
even did the old boot tab on msconfig but still nothing

You would do better here if you include some specs. Complete version number
of windows, motherboard type revision number, ram specs, any errors?

my apologies.. I thought about what I wrote and how dumb it sounded after I
hit the send button...Normally I would have put all the specs in but herein
lies the problem, I am helping a friend from across town who number 1 does
not know about these newsgroups and number 2 I do not have those specs
yet... I know he is running a 64 bit processor and he swears he is running
a 64 bit version of xp.. He just upped his memory from 1gig to 4 gigs and he
say it only shows 3 gigs... I probably should have waited until I had more
info before posting as since I have known about and have read these
newsgroups for a long time I made the mistake of just throwing something out
there with out thinking .. My apologies once again and will post back when I
have more info ...

Enable memory remapping in the BIOS.

Did you enable the Memory Remapping feature in your BIOS?
The memory remap is for 64 bit OSs only.

Check this screenshot out:

The about windows screen clearly identifies the machine in the screenshot as
running Windows XP Professional x64 edition. You can reach this screen by
opening my computer on the computer in question, selecting the help menu in
the explorer window that appears, and choosing "About Windows" from the list
of help options. If the About Windows screen doesn't clearly identify the
product as 64-bit edition then your friend isn't running 64-bit windows. The
reason I say this is because running a 32-bit version of windows is the most
likely explanation for only seeing 3Gb or so of RAM in windows despite
having 4Gb physically fitted.

If it's definately 64-bit windows then they need to check motherboard
support - also whether or not any particular bios settings or even a bios
update (not likely but you never know) need to be done before things will
work how you expect.
