3f0adb5211 Add the AMI Excalibur, a VLB OPTi 596/597 machine.
Also adds emulation of the OPTi 5x7 chipset, and introduces a clock divider for VLB on 64-bit bus systems.

eebdcf85cb Made writing to MSR 0x8B GPF on Intel Pentium/Pentium MMX
Windows Vista now (correctly) no longer works on these CPUs. IDT WinChip, AMD K6, VIA Cyrix III, and Intel P6 family CPUs are not affected.

0570e21f0f Applied Ryuzaki's Media menu patch, fixed a bug in cpu.c reported by ms. person, fixed bugs (and added a workaround for the Windows 2000 PCnet problems) to mem.c, and added a network packet queue to cap network speed (and do the actual rx poll in the main thread instead) for more stability, also some ES1371 fixes (but not enough to make it work on Linux). 2020-04-29 23:39:54 +02:00

600bb09f17 Added PS/2 Intel AMI keyboard controller type that always returns bit 6 of the input port as 1, fixes Intel Advanced/EV and Advanced/ZP SMM errors (with high-low beeps), and also IDE not found error behavior to fix IDE with some i686 BIOS'es. 2020-04-18 18:03:02 +02:00

275dd5a2f7 ACPI, SMM, and PIIX fixes, fixes quite a few boards, also fixed the Via Apollo series northbridge ID's, some CPU instructions on both 808x and 286+, and added SMM to 486's (Intel and AMD), WinChip and WinChip 2, and VIA Cyrix III, also removed the TC430HX and the Toshiba machine from the Dev branch. 2020-04-16 21:56:19 +02:00

61f0ae7954 Better ACPI implementation (currently only on PIIX4/PIIX4E/SMSC southbridges), finished the SMSC southbridge (but the Atrend BIOS still hangs, need to figure out why), and fixed Tandy EEPROM saving. 2020-04-13 20:01:47 +02:00

2a0b3eb9c5 Added PAE, ported K6, P6, and WinChip 2 timings to the old recompiler, added a bunch of CPU's to the old recompiler, done some x87 fixes for both recompilers, added PAE, and fixed root directory entries for single-sided 5.25" DD floppies in the New Floppy Image dialog. 2020-04-10 01:08:52 +02:00

d632f1dac9 Dynarec: Move CR0 into cpu_state
Some dynarec backends (x86-64, arm64) expect the offset between cpu_state and CR0 to within a certain limit, otherwise they crashes (e.g: "host_x86_MOV64_REG_ABS - out of range").
Move CR0 to the end of cpu_state, make sure the offset is within limit.

Helps NT4 and Win95 with dynarec on.

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

51bbebbfa3 Changes to the IBM 386/486 and RapidCAD CPUs
- Disabled the 'is486' flag and moved them to 386 timings
- Disabled cache on startup, enable-able later
- RapidCAD fixes (permanently disable L1, correct EDX reset)

111d82fa0c Preliminary VIA Cyrix III emulation
This adds preliminary emulation of the first-gen Samuel core, used in the VIA Cyrix III CPU, at clock speeds from 66 to 700 MHz. This also moves the 440BX emulation out of the dev-branch.

Things working:
- CPUID
- Windows 98SE
- Timings seem identical between WinChip/W2's integer section and this

Things left to do:
- 3DNow on old dynarec
- Half-speed FPU (currently simulated with WinChip 1 timings instead of WinChip 2)
