1.32 grr 28: <p>
1.327 miod 29: The OpenBSD/i386 port has been present since the inception of the project.
30: Over the years, more and more hardware support has been written
31: specifically for OpenBSD (such as the cryptographic accelerator drivers),
32: or adapted from FreeBSD and NetBSD.

38: <p>
39: It can be expected to install and run with minimal difficulty on most current
40: hardware.
1.736 mmcc 41: Machines using custom BIOS (such as older proprietary PCs, laptops, and some
1.327 miod 42: specialized server machines) may cause problems.
43:
44: <p>
1.488 matthieu 45: X Window System support is available for most graphics cards, using
1.755 tj 46: the X.Org server. As with other free operating systems, it is highly recommended
1.685 deraadt 47: that Nvidia cards are avoided since this vendor continues to show tremendous
1.683 deraadt 48: resistance towards releasing information that would allow X.Org to support their
1.684 jasper 49: hardware properly.
1.755 tj 50:
51: <p>
52: Due to the increased usage of <a href="amd64.html">OpenBSD/amd64</a>, as well
53: as the age and practicality of most i386 hardware, only easy and critical
54: security fixes are backported to i386. The project has more important things
55: to focus on.

1.718 nick 70: OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems,
71: including multi-chip, multi-core and/or hyperthreading designs.
1.753 bentley 72: To support SMP operation, a separate SMP kernel (<code>bsd.mp</code>) is
1.427 saad 73: included with the installation file sets.

1.330 miod 86:
87: <p>
88: OpenBSD/i386 can be installed to share the system disks with other operating
89: systems, such as MS-DOS, Windows or Linux, using the MBR/partition table
90: scheme, and an optional boot selector program.
91: Everyday operation is trouble free, but setup requires care, and several
92: operating systems, such as Windows 95, are known to be careless about
93: pre-existing MBR information.
94:
95: <p>
96: Also, some laptop computers use a specific partition as suspend-to-disk
97: storage, which should not be clobbered.
