86Box/src/win/win_d3d_fs.cc
OBattler 45204350b4 IDE hard disks and ATAPI CD-ROMS with DMA support now report as supporting UDMA modes, for the sake of future-proofing things; 
Changed the CD-ROM capabilities MODE SENSE page a bit;
Applied the S3 Trio and SVGA changes from PCem;
Fixed saving of the video renderer settings;
Fixed DirectDraw full screen;
Fixed crashes on soft reset in full screen.
