/*
* 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.
*
* CPU type handler.

Rewritten 808x CPU emulation core based on reenigne's XTCE, VisiOn, SnatchIt, and 8088 MPH now work correctly; Fixed PC speaker sound volume in PIT mode 0; A few CPU emulation clean-ups; Hard disk controller changing redone in a less messy way; Re-added the long-missing key send delay handling to the XT keyboard handler; Fixed a bug that was causing SLiRP not to work when compiled with MingW/GCC 7.3.0-2 or newer; Some serial mouse and port fixes; A lot of changes to printer emulation, mostly based on DOSBox-X; Printer PNG writer now uses statically linked libpng; Added support for the HxC MFM floppy image format and upped 86F format version to 2.12; Ported various things from PCem and some from VARCem; Added the S3 86c801/805 emulation (patch from TheCollector1995); Fixed and renamed the EGA monitor options; Better synchronized the 808x to the PIT and the CGA; Fixed the CGA wait state calculation; Cleaned up some things in mem.c; Fixed some things in the floppy emulation to make VisiOn get the correct errors from the copy protection disk; Fixed several renderer-related bugs, including the SDL2 renderer's failure to take screenshots; The Jenkins builds are now compiled with MingW/GCC 7.4.0-1 and include all the required DLL's.

More 808x fixed - fixed (kind of) the 8086 lock ups and the DRAM refresh wait states, also further fixed (and cleaned up) prefetch queue operation, applied a few warning fixes, and fixed the behavior of PUSH SP - anything that uses it to tell 808x apart from 286 is now fixed; Re-added the higher-clocked 8088's; Fixed PIT timings for 808x CPU's that don't run off an 14.3 MHz crystal; Fixed CGA cursor half blink rate setting - fixes insane cursor blinking speed in several cases; DMA now issues DMA refresh DRAM states on every channel; Gave the 1982 years to the previously emulated PC and XT's names, and added the 1981 IBM PC and 1986 IBM XT; Redid the PPI DIP switch redout for the PC/XT keyboard controller; Fixed a segmentation fault in hdc_ide.c that tended to occur on hard reset after switching machines; Implemented the port 3B8 color disable on the Hercules, Hercules Plus, and Hercules InColor cards; Fixed the joystick configuration dialog strings; Fixed a problem that would have prevented win_sdl.c from compiling with logging enabled.

Major commit, cleaning a lot of old stuff. IBM.H is gone, video stuff re-organized. Keyboard stuff reorganized. Machines that have their own video, mouse and/or keyboard now have all this in their machine file. Fixed and other cleanups here and there.

The Microsoft/Logitech Bus Mouse now handles the unusual handshake issued by MS MOUSE.SYS version 3.0, fixes said driver (though it should be checked against real hardware); Applied all the video-related PCem commits; The keyboard ALT+TAB detection now sends one extra ALT key down and up, so the guest does not get stuck in a menu bar.

Rewritten 808x CPU emulation core based on reenigne's XTCE, VisiOn, SnatchIt, and 8088 MPH now work correctly; Fixed PC speaker sound volume in PIT mode 0; A few CPU emulation clean-ups; Hard disk controller changing redone in a less messy way; Re-added the long-missing key send delay handling to the XT keyboard handler; Fixed a bug that was causing SLiRP not to work when compiled with MingW/GCC 7.3.0-2 or newer; Some serial mouse and port fixes; A lot of changes to printer emulation, mostly based on DOSBox-X; Printer PNG writer now uses statically linked libpng; Added support for the HxC MFM floppy image format and upped 86F format version to 2.12; Ported various things from PCem and some from VARCem; Added the S3 86c801/805 emulation (patch from TheCollector1995); Fixed and renamed the EGA monitor options; Better synchronized the 808x to the PIT and the CGA; Fixed the CGA wait state calculation; Cleaned up some things in mem.c; Fixed some things in the floppy emulation to make VisiOn get the correct errors from the copy protection disk; Fixed several renderer-related bugs, including the SDL2 renderer's failure to take screenshots; The Jenkins builds are now compiled with MingW/GCC 7.4.0-1 and include all the required DLL's.
