Dual boot Win 7 64 bit/Windows XP/Windows XP with 3 gb switch

I recently made my xp system to dual boot with win 7 also
both operating systems are on the same drive (but on a different partition)
I didnt have any problem (the dual boot menu that win7 made works normally to allow both operating system to boot when selected) except that now I dont have the option to use win xp with the 3GB switch
so I tried easybcd but I cant seem to get results
From what I read after selecting win XP I should get a second menu to chose between standard xp and xp with the 3GB switch
the boot ini (now edited by easybcd) looks like this:

; This boot.ini was automatically generated by NeoSmart Technologies' BootGrabber.exe
; Use EasyBCD from EasyBCD - NeoSmart Technologies to manage your bootloader

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP" /NoExecute=OptIn /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="XP 3GB" /NoExecute=OptIn /fastdetect /3GB

the files that should be placed on the winXP partition seem to be correct:

But unfortunately no menu appears and win XP boots directly when selected (as it was before using easybcd)
do you have any idea that would help?
Thanks in advance
