Adaptec U320 39320A-R Vista x64 BSOD

Hi,
I have been capturing and editing video for months using the MATROX RT.X2 platform in the computer described farther down.
Matrox unfortunatly never provided any RT.X2 XP64 drivers and I was not able to take advantage of the 12GB of memory. So I had XP32 and XP64 on double boot, using XP32 when I was editing video with the RT.X2 card.
In december 2008, Matrox, at last, released drivers and software for Vista 32 and 64 (not for XP64:sa, so I became interested in Vista 64. (I got the Business edition)
During installation, if Vista 64 sees the EIDE partitions and the Nvidia SATA 1,36TB RAID 0 stripe, it ignores the SCSI disks and yields a BSOD when loading the hostraid driver (of course the latest from ADAPTEC for Vista 64) :
''a driver has overrun a stack based buffer'' *** STOP : 0x000000F7(OxFFFFFA60023A19F0 ,Ox00002B992DDFA232,OxFFFFD466D2205DCD,0x0000000000000000)
So I was not able to install Vista on the 15k SCSI disk as previously done with XP64 (of course removed).
So I installed Vista 64 on a brand new formatted partition on the EIDE disk and things went well.
Using the device manager I succeeded installing ONE hostraid driver, being able to see ONE ADAPTEC RAID 0 SCSI Disk Device (the one on the A channel of the 39320A-R card).
Unfortunatly all attempts to install the second driver for the other raid 0 array and the SCSI disk resulted in the same BSOD and code.
I suspect a driver problem and sent a post to ADAPTEC but so far no answer.
I wonder if anybody has had a similar problem and how it was eventually addressed .
Best regards,
Adrien (adbast)

SCSIraidGURU might be able to help you with this. A bit too technical for me.
