86Box (formerly known as PCem-X, PCem Experimental or PCem Unofficial) is a system emulator based on PCem that supports older IBM PC systems and compatibles up to the VIA C3 period. It also includes accessories for these systems including graphics cards, network interface controllers, sound cards, storage controllers, mice and printers.

Supported guest operating systems[edit | edit source]

The following list includes all operating systems capable of running on the emulator. Satisfactory performance is not accounted for in the list.

Emulated hardware[edit | edit source]

  • CPU: Any CPU from an 8086/8088 to a Pentium II-era Celeron (Mendocino) and any board from 8086/8088 to Socket 370 (including Slot 1 and 2) is supported, including IDT/VIA/Cyrix/ST/ALi/AMD variants, with clock speeds ranging from 4.77 to 733 MHz. A dynamic recompiler is available, optional for 486, WinChip and VIA Cyrix III and mandatory for Pentium and later processors.
  • FPU: FPUs are emulated automatically for all 486DX and higher machines. For 8086/8088/286/386/486SX machines, a 8087/287(XL)/387/487SX FPU can be emulated optionally.
  • RAM: 16 KB to 1024 MB (depending on the machine)
  • Hard drives: Hard drives can be plugged into the MFM, RLL, XTA, ESDI, IDE, SCSI and ATAPI buses. Identified as "86Box 86B_HDxx".
  • CD-ROM drives: CD-ROM drives can be plugged into the SCSI and ATAPI buses.
  • Floppy disk drives: 86Box emulates 5.25" 180k, 360k, 720k and 1.2M drives, as well as 3.5" 360k, 720k, 1.25M, 1.44M and 2.88M drives.
  • Magneto optical drives: These drives can be plugged into the SCSI and ATAPI buses.
  • ZIP drives: These drives can be plugged into the SCSI and ATAPI buses. Both "ZIP 100" and "ZIP 250" types are supported.
