Applied all mainline PCem commits;
Fixed behavior of the FDC RECALIBRATE command for FDC's on certain Super I/O chips; Several 86F-related fixes; Added the Intel Advanced/ML (430HX, Socket 7, currently with non-working Flash) and Intel Advanced/ATX (430FX, Socket 7, works perfectly) motherboards; Fixed handling of DENSEL when the FDC is in National Semiconductors PC87306 mode; Brought 440FX initialization PCI parameters in line with Bochs; Brought PIIX3 initialization PCI parameters in line with QEMU.
