Added my name to all the emulator's files that I touched; Unfinished JEGA emulation based on akm's DOSVAX (AX-emulating fork of DOSBox), not yet hooked into the reset of the emulator.

* 86Box A hypervisor and IBM PC system emulator that specializes in
* running old operating systems and software designed for IBM
* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* This file is part of the 86Box distribution.

* Implementation of the Intel DMA controllers.

Cleanup, moving stuff out of ibm.h and such. Moved more configuration variables into main. Minor changes for multiplatform.

Added preliminary Adaptec 154x emulation, needs fixing in the Read 10 command. Made ATAPI derived from SCSI. Added proper S/G emulation for SCSI DMA. Added SCSI CD-ROM emulation, preserving all the former ATAPI commands as well.

extern void writedma2(uint8_t temp);
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.
