* FIXME: Find a new way to handle the switching of color/mono on
* external cards. New video_get_type(int card) function?
*
Updates to no longer have the selected machine's data as a global variable. Fixed the 'crash on unknown machine name in config' bug. Fixed some issues with the ROM loader, PS/2 M50 still doesnt work. Made the error message from dynld.c a DEBUG message. Fixed some stuff in the VNC driver (pending changes in the VNC DLL.) Cleaned up the MinGW Makefile, VC will follow. Added screenshots code to the D2D renderer.

* Author: Fred N. van Kempen, <decwiz@yahoo.com>
*
* Inspired by the "jim.c" file originally present, but a
* fully re-written module, based on the information from
* Schneider's schematics and technical manuals, and the
* input from people with real EuroPC hardware.
*
Applied relevent upstream patches. Cleaned up and fixed small things.

Many small fixes here and there. Devices now have a 'path' member, which usually points to a ROM file, or loader script. No more 'available' functions unless one is needed for special cases. Machines now can be 'configured' for mainboard settings etc. Machines are now devices as well (root devices). Regular devices now get a pointer to a 'parent' device. The machines table has been reduced to just a lookup table, machine info is now inside the machine file. Machine-specific CPU lists are now inside the machine file. Chipset implementations are now devices, and were moved to devices/chipsets/ Much work on individual machines done. All COMPAQ machines moved to dev-branch. Zenith SupersPORT moved to dev-branch. The i686-based machines (Tyan) released from dev-branch and cleaned up. Several new MFM and RLL disk controllers for XT, in dev-branch for now.

Many small fixes here and there. Devices now have a 'path' member, which usually points to a ROM file, or loader script. No more 'available' functions unless one is needed for special cases. Machines now can be 'configured' for mainboard settings etc. Machines are now devices as well (root devices). Regular devices now get a pointer to a 'parent' device. The machines table has been reduced to just a lookup table, machine info is now inside the machine file. Machine-specific CPU lists are now inside the machine file. Chipset implementations are now devices, and were moved to devices/chipsets/ Much work on individual machines done. All COMPAQ machines moved to dev-branch. Zenith SupersPORT moved to dev-branch. The i686-based machines (Tyan) released from dev-branch and cleaned up. Several new MFM and RLL disk controllers for XT, in dev-branch for now.

Re-worked the MVR framework to allow for custom RTC chips. Fixes EuroPC and Tosh T1000/1200. Cleaned up and re-integrated the Toshiba T1000/T1200 machines. Moved LZF files to floppy/, as that is the only module using them. Various bugfixes and cleanups here and there.

/* Validate the NVR checksum and save. */
Many small fixes here and there. Devices now have a 'path' member, which usually points to a ROM file, or loader script. No more 'available' functions unless one is needed for special cases. Machines now can be 'configured' for mainboard settings etc. Machines are now devices as well (root devices). Regular devices now get a pointer to a 'parent' device. The machines table has been reduced to just a lookup table, machine info is now inside the machine file. Machine-specific CPU lists are now inside the machine file. Chipset implementations are now devices, and were moved to devices/chipsets/ Much work on individual machines done. All COMPAQ machines moved to dev-branch. Zenith SupersPORT moved to dev-branch. The i686-based machines (Tyan) released from dev-branch and cleaned up. Several new MFM and RLL disk controllers for XT, in dev-branch for now.

Added the Western Digital WDXT-150 XTA disk controller. Updated SettingsUI to have a <configure> for disk controllers. Moved machine config code to machine/machine_table.c. Fixed more constness stuff in device.c and machine_table.c Fixed an issue in win_devconf.c (buffers too small.) Misc changes and fixes.
