OpenBSD/i386

Installation with Other Operating Systems:

The OpenBSD/i386 port can be installed to share the system disks with other operating systems such as MSDOS, Windows or Linux using the MSDOS MBR/partition scheme and an optional boot selector. Everyday operation is trouble free, but setup requires care and Windows '95 installation is known to be careless about pre-existing MBR/partition information. See the Installation Notes for more details.

Binary compatibility with other Operating Systems:

The OpenBSD/i386 port can run Linux, FreeBSD, BSD/OS, SVR4 (including Solaris), and IBCS2 binaries.

Supported Hardware:

The OpenBSD/i386 port works across a broad range of standard PC's and clones, with a wide variety of processors and I/O bus architecures. It can be expected to install and run with minimal difficulty on most current products. The cases where problems may be encountered are typically older proprietary PC's, Laptops or specialized server boxes that rely on a custom BIOS to paper over implementation differences.

OpenBSD does not currently support multiple processors, but will run using one processor on a multi-processor system board.

All mainstream i386 architecture CPU chips
- 386/486 (SX/DX)
- Intel Pentium/Pentium-MMX
- Intel Pentium Pro/II/III
- AMD K5/K6/K6-2/K6-3
- AMD Athlon
- Cyrix MediaGX/M1/M2
- Rise mP6
- IDT WinChip
- NexGen 586
Everything that is a clone of the 386 or up should work fine. The only CPU that is known to work poorly (due to flawed motherboard designs) is the Cyrix 386DLC.
All standard ISA, EISA, VLB, PCI, or PCMCIA bus based machines.

⁽¹⁾ Drivers for hardware marked with (1) are NOT included on the distribution floppies.

⁽²⁾ Support for devices marked with (2) IS included in the "generic" kernels, although it is not in the kernel on the installation floppy.

Unsupported Hardware

Unsupported hardware may be supported in the future, your donation of time, hardware, or documentation can accelerate this support!

"Micro Channel" MCA bus used in many IBM PS/2 models.
NCR 5380-based and 53400-based SCSI host adapters.
QIC-40 and QIC-80 tape drives. (Those are the tape drives that connect to the floppy disk controller.)

Sony and Panasonic proprietary CDROM interfaces.
Parallel-port ZIP drives (SCSI works fine.)
Cardbus controllers and adapters.
PCMCIA:
- 3COM 3c574.
- Memory cards.
