Extensive rework of CD-ROM image handling;
The settings save code now forces some devices' (SCSI disk, CD-ROM, etc.) pointers to NULL before resetting the machine - fixes segmentation faults after changing settings;
Added the NCR 53c825A and 53c875 SCSI controllers;
Fixed IDE/ATAPI DMA;
Slight changed to PCI IDE bus master operation.
Redid the way SCSI and ATAPI devices are handled;
Slight timings change in the NCR 5380;
Devices are now closed by device_close_all() in the reverse order of the one in which they were started;
Slight changes to some code in win/;
Added the WM_HARDRESET and WM_SHUTDOWN window messages for configuration manager purposes.
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.
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In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;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 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.
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.
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.
