1. Properly return the flat panel display bit in port 0x1bc6, fixes adapt.com and the corresponding Portable identification in the disk cmos.
2. Preliminary MDA mapping on the Plasma display, per bit 3 toggling of port 0x23c6.
3. Implemented port 0x17c6.
4. Cleanups.
Revamped and refactored the Compaq AT clone code, including a more correct Plasma emulation and undev branch the Deskpro 386 while adding the September 1986 and January 1988 bioses.
Added Compaq AT KBC strictly for the Deskpro 386 with the right settings, including the FPU bit.
The generic AMI/Quadtel/Phoenix IBM AT's don't issue the speed problems of the pure IBM AT beyond 8Mhz, so don't limit them to 8Mhz.
Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite;
Added device.c/h API to obtain name from the device_t struct;
Significant changes to win/win_settings.c to clean up the code a bit and fix bugs;
Ported all the CPU and AudioPCI commits from PCem;
Added an API call to allow ACPI soft power off to gracefully stop the emulator;
Removed the Siemens PCD-2L from the Dev branch because it now works;
Removed the Socket 5 HP Vectra from the Dev branch because it now works;
Fixed the Compaq Presario and the Micronics Spitfire;
Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470;
SMM fixes;
Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions;
Changed IDE reset period to match the specification, fixes#929;
The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset;
Added the Intel AN430TX but Dev branched because it does not work;
The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full);
Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types;
USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it);
Fixed NVR on the the SMC FDC37C932QF and APM variants;
A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX;
Some ACPI changes.
Selected XT and AT clones can use either their built-in FDC controller or an external one (the IBM AT and Compaq AT machines don't support booting from a 1.44M floppy so this makes the external floppy useful).
Added the FDC to the Adaptec AHA-154xCF ("2" variant) and defaulted to None to keep compatibility with existing FDC's.
