Author: uwe Date: 2007-09-25 03:31:35 +0200 (Tue, 25 Sep 2007) New Revision: 2807
Modified: trunk/LinuxBIOSv2/src/southbridge/nvidia/mcp55/mcp55_early_setup_car.c Log: As per suggestion from Yinghai Lu yinghailu@gmail.com this patch fixes the problems with PCI add-on cards not being detected or initialized on MCP55-based systems (PCI bridge decoding change).
I have tested this on the MSI MS-7260 (K9N Neo) with a PCI VGA card, which worked fine in any of the three PCI slots.
