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.

* system designs based on the PCI bus.

* Emulation of the Winbond W83877F Super I/O Chip.

* Winbond W83877F Super I/O Chip
* Used by the Award 430HX
*
Changes to logging - nothing (other than some parts of pc.c) uses the global pclog anymore (and logs will be almost empty (until the base set logging flags is agreed upon); Fixes to various hard disk controllers; Added the Packard Bell PB640; Fixed the InPort mouse emulation - now it works correctly on Windows NT 3.1; Removed the status window and the associated variables; Completely removed the Green B 486 machine; Fixed the MDSI Genius; Fixed the single-sided 5.25" floppy drive; Ported a CPU-related commit from VARCem.

The FDC is now a device_t, and the FDC code has been cleaned up; Merged floppy.c and fdd.c and renamed floppy_*.c (the floppy image format handlers) to fdd_*.c; Reading the AT or PS/2 keyboard controller status no longer clears the transmit timeout bit, fixes error 8601 (mouse error) on the IBM PS/2 Model 80; MMU translate and DMA physical reads and writes now go through _mem_exec instead of directly to ram[], should fix the last remaining problems with remapped mappings; Implemented the Sound gain dialog; Added the resource for the "New floppy image" dialog and the needed functions for the functionality of exporting the currently mounted floppy image as 86F, both of which should be finished in the next commit; Applied the CD-ROM fixes from the PCem commit; Added the "Keep ratio" option for full screen stretch.

Another massive cleanup run. Ibm.h no longer includes system header files. ROM loading simplified, and moved from mem.c to rom.c. Fixes in Makefile. Corrected mamy wrong includes. Removed old junk from days long gone. First phase of new SCAT chipset driver - no longer gives errors in BIOS, but NOT DONE YET.

void w83877f_init(void)
Intel SIO/PIIX/PIIX3 Turbo Reset Control is now properly implemented; Floppy disk controller is now COMPLETELY reset on hard reset; NukedOPL is now optional (but enabled by default) so people on older hardware can gain a few % of performance by going back to DOSBox OPL; *.CPP files now get all the correct optimization flags applied; Added NEC PowerMate V emulation - you can get into CMOS SETUP but it hangs before booting, and PCI graphics card don't work (yet).

The FDC is now a device_t, and the FDC code has been cleaned up; Merged floppy.c and fdd.c and renamed floppy_*.c (the floppy image format handlers) to fdd_*.c; Reading the AT or PS/2 keyboard controller status no longer clears the transmit timeout bit, fixes error 8601 (mouse error) on the IBM PS/2 Model 80; MMU translate and DMA physical reads and writes now go through _mem_exec instead of directly to ram[], should fix the last remaining problems with remapped mappings; Implemented the Sound gain dialog; Added the resource for the "New floppy image" dialog and the needed functions for the functionality of exporting the currently mounted floppy image as 86F, both of which should be finished in the next commit; Applied the CD-ROM fixes from the PCem commit; Added the "Keep ratio" option for full screen stretch.
