sorry
but i have hacked a ASROCK 88SE9123 little pci-e card with HIGHPOINT firmware and i can mount RAID , 0 , 1 , 5 , 10 at start up 
exactly as the Rocket Raid RR622
after with WINXP card is know as RR622 no problem 
problem is ASROCK card cannot find disks / RAID with WIN XP 
but if i connect RAID disks to a RR622 i find  that RAID is mounted correctly by ASROCK hacked firmware
possible that my hack is not exactly compatible wit RR622 original card firmware 
i have used a modified autoload ( no exactly the same as RR622 ) with same bios as RR622
i search always a solution but without 88SE91xx documentation that is hard !!

next week i received this little adapter SOCI8 to DIP8 for test with IOISATA SATA3 card S3-PCIE1XG201
