Extensively cleaned up and changed the CD-ROM code;
Removed CD-ROM IOCTTL (it was causing performance and stability issues);
Turned a lot of things into device_t's;
Added the PS/1 Model 2011 XTA and standalone XTA hard disk controllers, ported from Varcem;
Numerous FDC fixes for the PS/1 Model 2121;
NVR changes ported from Varcem;
The PCap code no longer requires libpcap to be compiled;
Numerous fixes to various SCSI controllers;
Updated NukedOPL to 1.8;
Fixes to OpenAL initialization and closing, should give less Audio issues now;
Revorked parts of the common (S)VGA code (also based on code from QEMU);
Removed the Removable SCSI hard disks (they were a never finished experiment so there was no need to keep them there);
Cleaned up the SCSI hard disk and Iomega ZIP code (but more cleanups of that are coming in the future);
In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;
Redid the way the tertiary and quaternary IDE controllers are configured (and they are now device_t's);
Extensively reworked the IDE code and fixed quite a few bugs;
Fixes to XT MFM, AT MFM, and AT ESDI code;
Some changes to XTIDE and MCA ESDI code;
Some fixes to the CD-ROM image handler.
The CD-ROM and Iomega ZIP drives now clear the error bit when the PACKET COMMAND command is issued, fixes the Iomega GUEST.EXE for DOS hang when run while the Iomega ZIP drive is empty.
The buffers are now memset'd to 0x00's on allocation;
The Iomega ZIP drive now issues an IRQ on receipt of the PACKET COMMAND command, fixes it on Windows 98 SE.
Reduced sound gain options to one (because the per-source gain does not work right);
Added the Diamond SpeedStar PRO (CL-GD 5428), per patch from TheCollector1995.
Did a tweak to mmutranslate() in mem.c, should increase performance again;
Added the ATi VGA Wonder and ATi VGA-88, made the ATi VGA Edge-16 use the correct BIOS.
Moved the two 440FX board along with the Pentium Pro and Pentium II CPU's to the Dev branch;
Applied the PCem commit that fixed PIIX IDE Bus Master initialization.
Fixed the behavior of the CD-ROM GET CONFIGURATION command when unimplemented features are requested;
Fixed the behavior of the CD-ROM READ DVD STRUCTURE command in some situations and made it correctly report 05/30/02 for incompatible format;
Reworked the PS/2 Model 80 Type 2 memory handling a bit;
The emulator now allocates the few MB of space needed for pages for the entire 4 GB RAM space at the startup and only memset's it to 0 on hard reset - should make sure DMA page reads from/writes to memory-mapped devices no longer crash the emulator on invalidating the memory range;
Applied app applicable PCem patches;
The PS/1 Model 2133 now also applies PS/2-style NMI mask handling - fixes the 486 recompiler on this machine;
Added the missing #include of "cpu/cpu.h" in io.c, fixes compiling when I/O tracing is enabled.
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.
Fixed the IDE device detection hang with > 8 GB hard disks;
Rewritten the SMC FDC37C932FR Super I/O chip emulation;
Added an early implementation of the PIIX4, currently not in the makefile because nothing uses it right now.
Changed the CD-ROM capabilities MODE SENSE page a bit;
Applied the S3 Trio and SVGA changes from PCem;
Fixed saving of the video renderer settings;
Fixed DirectDraw full screen;
Fixed crashes on soft reset in full screen.
Fixed the last remaining ATAPI DMA bugs;
Fixed IDE hard disk DMA;
Fixed PIIX bus master DMA read and write;
The Settings dialog now accepts more than 16 heads for IDE hard disks;
Added the IDE READ DMA ALT and WRITE DMA ALT commands;
Reenabled current CHS translation reporting, with bugfixes, hopefully the bugfixes will prevent certain larger hard disks from being detected as 250 MB.
