Yes I've been super Busy Fritz, sorry man!

For the RAID issue you can try to make a new BIOS for your card and see if that helps.

Download your original BIOS from HPT site, then try this with the downloaded tools included in the BIOS update, this helped me use RR 640 card with Intel BIOS enabled (Without this changed it failed to work)

There is a utility for programming HighPoint BIOS parameters for resolve compatibility

With Firmware upgrade ( run load.exe /C ) for the RAID Card :

And then test the option : Disable Reallocate EBDA in the HPT BIOS

Make two BIOS, one with that enabled and one with it disabled. Then test the disabled one first and see if it works, if not flash back the original or the one with it enabled.

If it doesn't work then you are probably out of luck unless you can get Gigabyte or Highpoint to help you directly with a BIOS.
