17f9ed66da DMA change of the day (December 31st, 2024) 
Actually add DMA PS/2 (MCA) XFER commands 0x9 (Set DMA Mask), 0xa (Reset DMA mask) and 0xb to addr 0x1a in both r/w parts.

02874f2ed2 DMA: Implemented autoinit mode in the PS/2 MCA side (although the bit is undocumented in said side, but documented in the ISA/PCI side). 
Networking: Added the WD8013EP/A MCA nic, which is more supported than the WD80x3ET/A plus an initial ram size configuration before POS configuration.
Sound: Added the Reply MCA OEM of SB16 with its own MCA POS ID and properly implemented the IRQ's and DMA's of the AdLib Gold in its EEPROM plus an initial configurable setting for them and an initial DRQ implementation into said card.

8767bb5894 Made reg 0x53 (read only) default temp val to 0x70 to satisfy xgaaidos.sys's detection. 
Apparently MCA Audio cards always want auto-init enabled.

345a61fa7c Removed the redundant mem_write_null* functions (the few mappings that use them, now use NULL pointers instead) and made the _phys function used by DMA not write to the exec buffer if the address has no write mapping (as in that case, it's clearly not intended to be writable), fixes #1332. 2021-03-30 02:16:01 +02:00

0faf6692c9 WARNING: CONFIGS MIGHT PARTIALLY BREAK WHERE DEVICE NAMES HAVE CHANGED. 
Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite;
Added device.c/h API to obtain name from the device_t struct;
Significant changes to win/win_settings.c to clean up the code a bit and fix bugs;
Ported all the CPU and AudioPCI commits from PCem;
Added an API call to allow ACPI soft power off to gracefully stop the emulator;
Removed the Siemens PCD-2L from the Dev branch because it now works;
Removed the Socket 5 HP Vectra from the Dev branch because it now works;
Fixed the Compaq Presario and the Micronics Spitfire;
Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470;
SMM fixes;
Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions;
Changed IDE reset period to match the specification, fixes #929;
The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset;
Added the Intel AN430TX but Dev branched because it does not work;
The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full);
Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types;
USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it);
Fixed NVR on the the SMC FDC37C932QF and APM variants;
A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX;
Some ACPI changes.

96228bc41d Overhauled the SiS 496/497 chipset emulation (and added the DRB locking to it) (later Zida Tomato 4DPS BIOS'es now work, and we now use the actual 1.72), fixed the W83787F and FDC37C932FR Super I/O chips, removed the no longer needed Acer M3A registers (that's now correctly handled as FDC37C932FR GPIO), and a number of bugfixes here and there. 2020-06-29 01:10:20 +02:00

a505894a10 Move all include files to src/include 
- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root
