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 3072 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.
