Running 2 MSI Cards for Quad Setup but only seeing 2 montiors

Question

I built this computer about 8 months ago and all has worked great till my primary C drive failed, replaced the drive and have been reloading everything but can't seem to get my 2 video cards to work like they did previously.
Homebuilt system, xp pro, abit IP35 motherboard, intel quad core processor, 2 geforce 8600 GT video cards (both have dual dvi out) so I have 4 monitors on these 2 cards).
This is a link to the exact card I have 2 of them in this machine on that abit Ip35 motherboard.
MSI NX8600GT-T2D256EZ

This is what I have done
I loaded up windows xp, loaded up the abit motherboard drivers etc, updated all of the windows sp3, ie7, all security and driver updates, then I put in the msi disc I got with the cards loaded the drivers for xp, restarted and went into the nvidia control panel to adjust the multimonitor display setup (setup of multiple displays under display options).
I also hit the  "my monitor is not showing" option but still didnt pick up monitors 3 and 4, like it did originally when i built this setup.
I then went into the device manager and confirmed under display both geforce 8600 cards were showing and went to both and even tried manually loading the drivers from the cd rom disc (did that successfully) but still after a restart nogo on the 3 & 4 monitors showing up.
This is probably such a silly question but i cant remember how i got it all to load up and work before, and im sorta stumped as to what im doing wrong, i confirmed both cards are fully seated (and device manager does show both cards and shows both are functioning properly with drivers loaded), is there anything I need to check setup or adjust in the bios possibly?

Answer 1

Figured it out after a bit of sleep and re-thinking it, had to right click on desktop / properties / settings, then under display I had to choose each of the 4 different monitors one at a time and check the "extend windows desktop onto this monitor" box, once I did that for all 4 and hit apply, i was able to position each box where I wanted it and all worked great.
Sorry for the question here I was just getting really frustrated after not being able to figure it out last night.
