How to install Raid 0 Driver after installed XP

I need to created Raid 0 for my rig with win XP installed on it. I just bought 2 x 500 Gb Seagate SATA HDs.
After Reading the manual come with GA-EP45-DS4P. It said the RIAD driver must installed BEFORE in order windows to recognized the raid.
I don't want to format my hard disk to do this ! Is there anyway I can create raid 0 and install the driver after installed windows XP ?
I did try to created the Raid 0, but the windows XP failed to load and keep reboot by itself continuously because it missed the drivers .
Thanks for any helps !!

I did as you said and windows XP recognized the two drives as drive D: and E: I Goto bios setup, enable SATA as Raid, Saved the setting , after the rebooted, the new windows popup said I have new Raid and ask me to configure the new raid to raid level 0 , After I set the two new drives to raid 0, Assigned new raid 0 volume, saved the setting and reboot system again. Here it come the problem !!? After reboot and POST when it start loading windows the system keep resetting by itself at the point where the winXP logo appeared and keep doing it endlessly ???!
I had to hard resetting by press the reset button on my case. Then get into raid menu from bios, delete the raid volume, saved the setting and reboot system. the windows XP boot successfully .!!!
"The win XP could NOT load the raid because it missed the driver "
That 's what it said in manual book ! Is there anyway I can load the raid driver into win XP recognized the raid volume after I setup the raid volume from the bios so that when win XP loading it can recognized the volume ??
Thanks for all Inputs

It was my mistake not clarify my question:
I had 3 HDs:
Master HDD is Seagate 1 TB Contain Win XP OS and applications.
The others two HDD are 2 x 500 Gb Seagate SATA. These two are the one I want to create Raid 0 volume, there is no OS or applications on these 2 HDD, just want to create raid 0 from these two HDD and I don't want to transfer Win XP OS to these 2 HDDs.
The system boot from my 1 TB Seagate HD.
I just want to create Raid 0 from these 2 x 500 Gb Seagate for my Video Editing storage.
Since I created raid 0 from bios, the windows XP refuse to boot even if I set the bios to boot from Seagate 1TB not from raid volume
any idea why this happen ???

Thanks for your info SomeJoe !
I got this working this mornibg; What I Did:
1)- Load the Matrix Storage Manager driver ( from Intel Website ).
2)- Save and reboot computer.
3)- Go to GA-EP45-DS4P Bios enable RAID / AHCI to enable save and exit BIOS.
4)- Enter the RAID Configuration menu from Boot Up ( Pressed Ctrl + I ) configed 2 x 500 Seagate HDD as raid 0, save and exit.
This time the win XP boot up suceessfully and showed I had Raid 0 volume in my system.
Now I can go ahead to use my Adobe Master collection CS3 for my wedding from CD to DVD's
Thanks again for all helps and info ! You're the man, SomeJoe !

Hello,

I've been searching high and low for some help.. I have the same problem, I think.

I have just built my new pc, 3 hard drives, one 80GB Seagat Barracuda with Vista Business, then I have a nother two 500 Seagates. Those 2 are not formatted yet.

My motherboard is a ASUS M3a78-EMH-HDMI

At the beginning I tried going into the BIOS to change sata type to raid etc (I found that info elsewhere), but then when I rebooted it wouldn't recognise any of my drives.


I needed tio use the internet so the only thing i could do was to change it back and just install the OS. I don't have a clue what to do. Do need another controller? I need to buy one? I have raidxpert installed from my MOBO CD but it's just jubberish to me, I don't know if that's the raid drivers or what.

Please help.

i also got the problem. I installed window xp after that i enable raid in bios and it already had raid 1, end up my window cant boot up. it displayed error message " error loading operating system " anybody could help me please? and also even cant go to bios setup.
