1.32 grr 29: <p>
1.327 miod 30: The OpenBSD/i386 port has been present since the inception of the project.
31: Over the years, more and more hardware support has been written
32: specifically for OpenBSD (such as the cryptographic accelerator drivers),
33: or adapted from FreeBSD and NetBSD.

40: It can be expected to install and run with minimal difficulty on most current
41: hardware.
1.736 mmcc 42: Machines using custom BIOS (such as older proprietary PCs, laptops, and some
1.327 miod 43: specialized server machines) may cause problems.
44:
45: <p>
1.488 matthieu 46: X Window System support is available for most graphics cards, using
1.682 deraadt 47: the X.Org server. As with other free operating systems it is highly recommended
1.685 deraadt 48: that Nvidia cards are avoided since this vendor continues to show tremendous
1.683 deraadt 49: resistance towards releasing information that would allow X.Org to support their
1.684 jasper 50: hardware properly.

64: <p>
1.718 nick 65: OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems,
66: including multi-chip, multi-core and/or hyperthreading designs.
1.753 bentley 67: To support SMP operation, a separate SMP kernel (<code>bsd.mp</code>) is
1.427 saad 68: included with the installation file sets.

1.330 miod 81:
82: <p>
83: OpenBSD/i386 can be installed to share the system disks with other operating
84: systems, such as MS-DOS, Windows or Linux, using the MBR/partition table
85: scheme, and an optional boot selector program.
86: Everyday operation is trouble free, but setup requires care, and several
87: operating systems, such as Windows 95, are known to be careless about
88: pre-existing MBR information.
89:
90: <p>
91: Also, some laptop computers use a specific partition as suspend-to-disk
92: storage, which should not be clobbered.

95: More details on this process can be found in the
96: <a href="faq/faq4.html">Installation Guide</a> and

1.745 tb 125: <li><strong>CD image</strong> (installXX.iso)

1.745 tb 127: The CD ISO provides an <i>El Torito</i> no-emulation boot image
1.610 tom 128: that includes almost all OpenBSD drivers.
1.330 miod 129: This also includes minimal USB support (storage devices and keyboard).<br>

141: find that the missing drivers are ones which need large microcodes to run,
1.432 nick 142: such as for rare SCSI cards, gigabit ethernet cards, or RAID devices.<br>
