No errors on startup with IBM XT or IBM PC BIOS.Fixed bug in floppy-disk controller emulation.Added SVGA emulation for Tseng Labs ET4000.Added Paradise EGA and Trident VGA emulation.Added Amstrad PC1640 and IBM AT emulation.Machine: IBM PC, IBM XT, Tandy 1000, Amstrad PC1512, Sinclair PC200.CPU: Intel 8088 running at 4.77 MHz and Intel 8086 running at 8 MHz.Versions of PCem from v0.5 until v8 have been removed from the official webpage, due to the use of the MAME OPL2/ OP元 emulation code from when it was not yet licensed under a GPL-compatible license. FreeBSD), and BeOS 5, which only works on the Award SiS 497 motherboard. Other operating systems are also supported on PCem, such as versions of Linux that supports the Pentium processor, BSD derivatives (e.g. Earlier versions of OS/2 requires the hard drive to be formatted prior to installation, while OS/2 Warp 3 until Warp 4.5 requires an unaccelerated video card to run. ![]() Similar to Virtual PC, Bochs and QEMU, it emulates almost all versions of Microsoft Windows until Windows Vista (including Service Pack 2), MS-DOS, FreeDOS and CP/M-86 are also supported. However, starting with PCem v13, the emulation of NE2000 was officially added. However, there are some shortcomings regarding Voodoo emulation such as the lack of mipmapping, slightly wobbling triangles, lack of speed limiting, and inaccurate refresh rates on almost every resolution (except As of PCem v11, a separate recompiler has been added for Voodoo emulation, making it faster to emulate the Voodoo graphics card.Īn unofficial build of PCem allows usage of SLiRP/ WinPcap as a networking interface, plus emulated NE2000 and Realtek RTL8029AS Ethernet cards. Voodoo cards are also emulated since PCem v10 and PCem v12, which added support for Voodoo 2 and various optimizations. PCem also emulates some sound cards, such as the AdLib, Sound Blaster (including the Game Blaster), Sound Blaster Pro, Sound Blaster 16, Sound Blaster AWE32, Gravis UltraSound, Innovation SSI-2001, Aztech Sound Galaxy Pro 16, Windows Sound System, Ensoniq AudioPCI 64V/ES1371, and Sound Blaster PCI 128. PCem can also emulate various video cards such as the ATI Mach64 GX and the S3 Trio32/64/Virge series. PCem can emulate different graphic modes, this includes text mode, Hercules, CGA (including some composite modes and the 160 × 100 × 16 tweaked modes), Tandy, EGA, VGA (including Mode X and other tweaks), VESA, as well as various video APIs such as DirectX and 3Dfx's Glide. PCem simulates the BIOS cache, which relies on the processor rather than on system memory. However, unofficial builds of PCem (PCem-X and PCem-unofficial) also supports IBM PC compatible systems/motherboards (from 1996 until 2000) that supports Intel Pentium Pro/Pentium II processors. PCem emulates various IBM PC compatible systems/motherboards from 1981 until 1996, this includes almost all IBM PC models (including the IBM PS/1 model 2121 and the IBM PS/2 model 2011), some American Megatrends BIOS clones (from 1989 until 1994), Award BIOS systems (Award 286 clone, Award SiS 496/497 and Award 430VX PCI), and Intel Premiere/PCI and Intel Advanced/EV motherboards. However, the current developer of PCem has a main concern that the recompiler is not fast enough to emulate the Intel Pentium Pro/Pentium II processors yet. Yet a rather fast processor is needed for full emulation speed (such as an Intel Core i5 at 4 GHz). A recompiler has been added in v10.1, being mandatory for P5 Pentium and Cyrix processors and optional for i486 processors and IDT WinChip processors. ![]() PCem is capable of emulating Intel processors (and its respective clones, including AMD, IDT and Cyrix) from Intel 8088 through the Pentium Tillamook MMX/Mobile MMX processors from 1997 until 1999. During the interim period with no maintainer, the project's forums were closed. ![]() A new maintainer, Michael Manley, was appointed on 18 December 2021. On 14 June 2021, lead developer Sarah Walker announced her departure from the project. Originally developed as an IBM PC XT emulator, it later added support for other IBM PC compatible computers as well.Ī fork known as 86Box is also available, which includes a number of added features, such as support for SCSI and additional boards. PCem (short for PC Emulator) is an IBM PC emulator for Windows and Linux that specializes in running old operating systems and software that are designed for IBM PC compatibles.
