HI,
Current version of Seabios is causing blue screen on Windows2003 when 64bit PCI resource is present and occupies high memory.
BSOD Error code is: 0x000000A5 (0x02, 0xFFFFfADF6A446880, 0x1, 0xFFFFFADFAA34690)
The issue is localized, it is related to presence of 64bit resource in _CRS method.
If we disable a 64bit region from _CRS the Win2003 load normally but this doesn't allow Windows to use 64bit resources.
At the moment I have no idea how to fix this. Please help!
I wonder if Windows 2003 does not support ConcatenateResTemplate. The patch below is obviously wrong, but should let you check if this is the issue:
