P7N Diamond - JMicron JMB363 RAID w/PATA

Question

So I've upgraded from 975XPUE (RIP)to P7N Diamond and have WinXP running somewhat stable.  Amazingly, this is using prev OS install from 975X mobo.  Somehow I've managed to get new chipset drivers installed and all hardware recognized.  I'll probably do a clean install down the road but would like to pick up a new drive first to keep old drive for backup.
Anyhoo, I'm having issues getting the JMicron controller to configure my 2 x IDE drives into a RAID 0 array.  P7N Diamond is using JMB363 controller whereas 975X had the older JMB361.  And the older mobo/JMicron chipset was able to run PATA drives in RAID 0 just fine.
But now I'm stuck.  This is partly my fault.  When I originally swapped mobos and booted the system, the JMicron BIOS actually recognized my existing RAID 0 array.  I had set the bios option to "RAID" and the subsequent JMicron boot screen listed both drives as "RAID Inside". 
However, I wasn't initially sure which BIOS options referenced which IDE controllers.  Turns out, the NVidia controller (primary port) is in the sub-menu and only has options for IDE and RAID.  The JMicron controller (secondary port) is in the top menu and has options for IDE, RAID, *and* AHCI.  This misled me into thinking the BIOS options were reversed, that the top menu referenced NVidia primary controller and the submenu referenced JMicron secondary.  At least, that's how it was done on the 975X.  So, in a brilliant decision, I changed the RAID option on JMicron controller to AHCI (because that's how the Intel controller on my 975X was configured and how I thought WinXP would expect to see the primary boot drive).
On subsequent boot, JMicron screen now showed PATA drives as "Non-RAID".  So, my array was lost, but luckily I only kept expendable files on RAID.  But now I'm not able to rebuild a new array.  Resetting the BIOS option to RAID mode and entering the JMicron configuration will display both drives in Non-RAID config.  But if I try to create a new array, it says "no enough drive available".  If I try to revert drives to Non-RAID or delete a RAID array, it says all drives are already Non-RAID and there are no existing arrays to delete.
So I'm lost.  I've seen posts in some msg forums claiming JMicron can only support RAID on SATA drives.  But the JMB363 only has eSATA ports.  And I can't imagine only supporting external devices for RAID?? That and I know from personal experience that JMB361 was able to put PATA drives into RAID, and that the JMB363 recognized my old array initially (before I foolishly ruined the config).
Any ideas how I can create a new RAID 0 w/ 2xPATA on the P7N Diamond?  Has anyone else attempted this?
Things I've tried: 
1)  Deleting partitions on PATA drives and leaving empty;
2)  Deleting partitions on PATA drives and creating new;
3)  Resetting BIOS option for JMicron to IDE and repeating steps 1 and 2 above
3)  Resetting BIOS option for JMicron to AHCI and repeating steps 1 and 2 above
3)  Resetting BIOS option for JMicron to RAID and repeating steps 1 and 2 above
Want to try next:
1)  Remove PATA drives from current sys and lowlevel format in a diff machine
TIA
(config is same as in sig except substitute P7N Diamond for 975X PUE)

Download the latest driver directly from JMicron (1.17.40.05):

Looking in Device Manager under IDE Controllers, I have 4 Primary IDE Channel, 4 secondary IDE Channel, and 4 Standard Dual Channel PCI IDE Controller..
When the drivers are correctly installed, the JMicron controller should appear under SCSI- and RAID Controllers.
