Sony :: New Z QuadSSD + Extra SSD CPU Bug

I managed to write a fix for the ACPI bug which was preventing proper power management if you add one more 2.5" SSD/HDD to the Quad SSD VPC-Z11.

Basically, it is a windows driver which loads very early (immediately after NT kernel and HAL) and dynamically patches the ACPI tables with the proper ones (which I dumped from the "bug-free" system state)

NOTE - the patch is for the very experienced users, so PLEASE read the readme.rtf VERY CAREFULLY and please think carefully whether you want to proceed further.

Naturally - It goes without saying that this is a potentially dangerous process, and that usage of any info from the attached vaiopatch.zip file is at your own risk No, seriously, this can make your computer unbootable so please check the readme and do consider if you can perform the repair steps before trying to do anything! System backup is a must.

I believe I documented the process well, so that people with moderately advanced system knowledge can use this patch. There is a pre-compiled driver available in the /example directory, but that driver is valid for systems which have EXACTLY the same configuration as mine (all described in Readme)

If you have a different system (e.g. ACPI tables at different locations, different CPU from i7-620M, etc..), you will need to extract good ACPI data and re-build the driver by yourself. This process will require Windows DDK and some C/C++ programming knowledge. I cannot provide too much support there unfortunately, outside from I already wrote in readme.
