Joe, That sounds brutal! I would totally take the advice of going non-gigabyte, but I have a P35-DS3R board with 8 SATA ports that is about to become surplus when I upgrade my desktop computer. I'm not buying probably not buying Gigabyte again for the desktop, by the way.
Problem is there is not option to disable and I am already on the latest BIOS.
Do you know if there is any truth to the one person reporting he might have gotten rid of HPA by setting the SATA controllers to AHCI mode ?
I asked in another thread if running the Parity drive off of an add-on SATA controller would be a solution, but if understood your description, that would only solve some of the problem, what do you think?
By the way, MrLeeTek - This HPA (Host Protected Area) is created by the Gigabyte feature called "Virtual Dual BIOS", which is mentioned in the featurelist for the motherboard (at least in the manual). I agree Gigabyte is not being very open about it.
