I have searched here for a couple days and read a bunch of posts - some of which I have tried.
I am NOT trying to go back down to Win 7 (though I really like Win 7)
I am trying to stick with Win 8.1.
I was running BIOS P11-A1 and suddenly started having trouble with the USB 3.0 controller.
I read some posts here and on other forums that stated I should see if there is a BIOS update.
There are actually four for this machine and so I started with the oldest one P11-B0L
To be honest the instructions in the README pdf file were not that helpful
but I found soem great data on the AMI website that helped me update to P11-B0L.
I ran the BIOS-DOS.BAT file first but got this error: "4 - Error: ROM File ROMID is not compatible with existing BIOS ROMID"
So I went ahead and ran the AFUDOS file without all the parameters in the batch file and everything updated fine.
But I am still having troubles with the USB 3.0 controller and the process just seemed to be fairly complex.
Both my HP's and three other Dell's had Flash BIOS programs, or simple instructions that worked with no problems.
Was I just getting lucky with them and there is some hidden UEFI and/or MS-DOS secret ritual that I am missing here ?
Am I perhaps using the incorrect BIOS update file - and if so which one should I use ?
