TC1995 c91f2255ad Vast overhaul for the Mach8/32/8514/A (March 29th, 2025)
1. Implemented the FIFO test data to pass some tests of the Mach8 POST ROM and tests (not complete yet).
2. Overhauled the mode switches again, but this time with way less hacks and more on manual instructions.
3. Use a function pointer to determine if the Mach8 type used is a VGA combo or add-on.
4. Mach32 mode tests are no longer incorrectly green (was caused by improper pixtrans parts).
5. Implemented overscan color to the Mach32 as well as the CRT offset.
6. And fixed a PCI LFB GPF issue with the Mach32 2.3 drivers on Win3.1x.
7. Implemented memory boundary for both the Mach32 SVGA and its accelerator.
8. Added undocumented ports used by the FIFO (such as ports 0x8AEE and 0xEAEE).
9. Plus resetting the device right a la s3.
10. Temporarily switched the bus type of the Mach8 to 8-bit in both MCA and ISA variants.

86Box

Build Status License Latest release Downloads

86Box is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.

Features

  • Easy to use interface inspired by mainstream hypervisor software
  • Low level emulation of 8086-based processors up to the Mendocino-era Celeron with focus on accuracy
  • Great range of customizability of virtual machines
  • Many available systems, such as the very first IBM PC 5150 from 1981, or the more obscure IBM PS/2 line of systems based on the Micro Channel Architecture
  • Lots of supported peripherals including video adapters, sound cards, network adapters, hard disk controllers, and SCSI adapters
  • MIDI output to Windows built-in MIDI support, FluidSynth, or emulated Roland synthesizers
  • Supports running MS-DOS, older Windows versions, OS/2, many Linux distributions, or vintage systems such as BeOS or NEXTSTEP, and applications for these systems

Minimum system requirements and recommendations

  • Intel Core 2 or AMD Athlon 64 processor or newer
  • Windows version: Windows 7 Service Pack 1 or later
  • Linux version: Ubuntu 16.04, Debian 9.0 or other distributions from 2016 onwards
  • macOS version: macOS High Sierra 10.13 or newer
  • 4 GB of RAM or higher

Performance may vary depending on both host and guest configuration. Most emulation logic is executed in a single thread; therefore, systems with better IPC (instructions per clock) generally should be able to emulate higher clock speeds.

It is also recommended to use a manager application with 86Box for easier handling of multiple virtual machines.

It is also possible to use 86Box on its own with the --vmpath/-P command line option.

Getting started

See our documentation for an overview of the emulator's features and user interface.
