main reason why my new HP p6501c came with 64 bit windows 7 premium cpu i3
8gb ddr3 and I installed empty HD to operate win xp professional where many of my
valuable programs operate on fat 32 / 32 bit win xp pro I need to choose HD 1 with xp pro and HD 2 with win 7

Your explanation is a mess. There is no "FAT64" & I doubt the XP HDD is formatted as FAT32. More than likely, both drives are formatted as NTFS.

Your XP installation will not work on the new system. XP will have to be reinstalled using the "repair install" method. But since XP 32-bit only recognizes up to 4GB RAM, I suspect you're going to have problems with an 8GB system.

You're going to need a boot manager:

yes I may mal explained technically window xp pro is formatted as you said but
my programs such as adobe creative suite 2 runs as fat 32 on xp fort example;
if win xp pro recognizes only 4gb ddr ram I can take off rams to down size from 8 gb to 4gb ddr3 which can run both xp pro and windows 7 ; now the question is can I run
xp on one internal drive A and win 7 on the other drive B in the same hp desktop
hp model p6501c ; does bios recognizes both OS as long as - as you said - 64 bit

A OS that can't address memory beyond a limited point isn't bothered by what may be beyond its addressable limit. It simply doesn't see it. If it was a concern you just put a maxmem switch in the xp line of the boot.ini limiting xp to only see 4gig of ram.

No ram removal required.

You will need no other boot manager than the one that comes with windows.

arnaasak you can install XP on the added hard drive. Your issue will be that after the install only XP will boot and not Windows7.

You have to do a repair of the Windows 7 boot loader.

Thanks wonderer but still my question is not clearly answered to make me understand .. I know you can partition 1 hard drive to install 2 operating systems;
and when I start using partition magic the boot magic ask me which partition / which OS windows I would like to run .. this is in case of 1 internal drive partitioned .. but here my situation is different because I have 2 internal hard drives A & B ; I was told
there is a raid card in my HP desk top model p6501c i3 processor, my desktop recognize when I boot my pc to on / start , my pc recognize there is an empty HD A
(supposed to install win xp pro ) then retrying to boot thereafter windows 7 home premium , but it does not ask me when I put start bottom on which drive or which OS
win xp pro ( drive A) or win 7 home pre (drive B) that I need to use or boot ? I need
to operate each separately because of xp pro productivity programs that cost me a lot of money I can not purchase it again ; is it possible to do that still following your previous advice .. do I need a boot magic or just a repair ? is there a realistic solution How , any software to download further ? or the sole solution left is to use win 7 ultimate or professional to run win xp pro mode ? and in the later case sould
I use the second drive to mirror the first ? any help or answers thanks ?

arnaasak review the KISS principle [google it]
you are making this way more complicated than it is.

You don't need partition magic at all when using MS products exclusively.

One internal drive or 4 internal drives, multiple partitions on a disk or all disks, makes no difference. It is all the same

You can't raid now so forget that path.

"I need to operate each separately" Of course. That is what a multiboot does.

Follow the instructions above once you have uninstalled Partition Magic. Boot magic will be removed from the mbr with the xp install. Then do the windows 7 repair and you will have your multiboot.

But for heavens sake backup everything you have on Win7 first.
