86Box/src/cpu/codegen_ops_misc.h
OBattler 552a87ea3d Added the IBM 5161 ISA expansion for PC and XT; 
Cleaned up the parallel port emulation, added IRQ support, and made enabling/disabling per port;
Added the Award 430NX and the Intel Classic/PCI (Alfredo, 420TX);
Finished the 586MC1;
Added 8087 emulation;
Moved Cyrix 6x86'es to the Dev branch;
Sanitized/cleaned up memregs.c/h and intel.c/h;
Split the chipsets from machines and sanitized Port 92 emulation;
Added support for the 15bpp mode to the Compaq ATI 28800;
Moved the MR 386DX and 486 machines to the Dev branch;
Ported the new dynamic recompiler from PCem, but it remains in Dev branch until after v2.00;
Ported the new timer code from PCem;
Cleaned up the CPU table of unused stuff and better optimized its structure;
Ported the Open-XT and Open-AT from VARCem, the Open-AT is in the Dev branch;
Ported the XT MFM controller rewrite and adding of more controllers (incl. two RLL ones), from VARCem;
Added the AHA-1540A and the BusTek BT-542B;
Moved the Sumo SCSI-AT to the Dev branch;
Minor IDE, FDC, and floppy drive code clean-ups;
Made NCR 5380/53C400-based cards' BIOS address configurable;
Got rid of the legacy romset variable;
Unified (video) buffer and buffer32 into one and make the unified buffer 32-bit;
Added the Amstead PPC512 per PCem patch by John Elliott;
Switched memory mapping granularity from 16k to 4k (less than 1k not possible due to internal pages);
Rewrote the CL-GD 54xx blitter, fixes Win-OS/2 on the 54x6 among other thing;
Added the Image Manager 1024 and Professional Graphics Controller per PCem patch by John Elliott and work done on VARCem;
Added Headland HT-216, GC-205 and Video 7 VGA 1024i emulation based on PCem commit;
Implemented the fuction keys for the Toshiba T1000/T1200/T3100 enhancement;
Amstrad MegaPC does now works correctly with non-internal graphics card;
The SLiRP code no longer casts a packed struct type to a non-packed struct type;
The Xi8088 and PB410a no longer hang on 86Box when PS/2 mouse is not present;
The S3 Virge on BeOS is no longer broken (was broken by build #1591);

Compaq Portable now works with all graphics cards;
Fixed various MDSI Genius bugs;
Added segment limit checks and improved page fault checks for several CPU instructions - Memphis 15xx WINSETUP and Chicago 58s WINDISK.CPL no longer issue a GPF, and some S3 drivers that used to have glitches, now work correctly;
Further improved the 808x emulation, also fixes the noticably choppy sound when using 808x CPU's, also fixes #355;
OS/2 installer no logner locks up on splash screen on PS/2 Model 70 and 80, fixes #400.
