the following patch was just integrated into master: commit 931df3a96bce9e3bc6f0d1058c301c49bee63747 Author: Martin Roth martin.roth@se-eng.com Date: Wed Jan 16 17:50:32 2013 -0700
F15tn / Hudson: Change SATA NumOfPorts register setting
The Number of Ports register says that it should be set to the maximum number of ports supported by the silicon. AGESA was setting this to be the number of enabled ports. If port 1 was the only port with a drive, this value got set to 0, indicating 1 port. This causes SeaBIOS to only look at port 0 and quit, never finding the drive on port 1.
Dave Frodin: I also verified that this patch allows a SATA drive plugged into port 2 to be detected without a device in port 1.
