#include "cpu/cpu.h"
Vastly overhauled the UI, there's now a completely new Settings dialog as well as a status bar with disk activity icons and removable drive menus; Thoroughly clean up the code to vastly reduce the number of compiler warnings and found and fixed several bugs in the process; Applied all mainline PCem commits; Added SCSI hard disk emulation; Commented out all unfinished machines and graphics cards; Added the AOpen AP53 and ASUS P/I-P55T2 machines as well as another Tyan 440FX machine, all three with AMI WinBIOS (patch from TheCollector1995); Added the Diamond Stealth 3D 3000 (S3 ViRGE/VX) graphics card (patch from TheCollector1995); Added the PS/2 XT IDE (AccuLogic) HDD Controller (patch from TheCollector1995); Added Microsoft/Logitech Bus Mouse emulation (patch from waltje); Overhauled the makefiles (patch from waltje); Added the Adaptec AHA-1542CF SCSI controller (patch from waltje); Added preliminary (but still unfinished) Adaptec AHA-154x SCSI controller BIOS support (patch from waltje); Added an ISABugger debugging device (patch from waltje); Added sanity checks to the Direct3D code.

This is similar to the model 2011 but some of the functionality has moved to a
chip at ports 0xe0 (index)/0xe1 (data). The only functions I have identified
are enables for the first 512kb and next 128kb of RAM, in bits 0 of registers
0 and 1 respectively.
Port 0x105 has bit 7 forced high. Without this 128kb of memory will be missed
by the BIOS on cold boots.
The reserved 384kb is remapped to the top of extended memory. If this is not
done then you get an error on startup.

Properly fixed Adaptec AHA-1640 MCA adapter, setup is handled directly by the ADF file in the reference disks. Re-introduced the Acer V35n machine, but with a proper bios (r01-c0.bin instead of the service one). MCA serial and parallel initialization fixes alongside the ISA PS/1 and PS/2 Model 30 ones.
