1.327 miod 36: The OpenBSD/i386 port has been present since the inception of the project.
37: Over the years, more and more hardware support has been written
38: specifically for OpenBSD (such as the cryptographic accelerator drivers),
39: or adapted from FreeBSD and NetBSD.

46: It can be expected to install and run with minimal difficulty on most current
47: hardware.
1.736 ! mmcc 48: Machines using custom BIOS (such as older proprietary PCs, laptops, and some
1.327 miod 49: specialized server machines) may cause problems.

51: <p>
1.488 matthieu 52: X Window System support is available for most graphics cards, using
1.682 deraadt 53: the X.Org server. As with other free operating systems it is highly recommended
1.685 deraadt 54: that Nvidia cards are avoided since this vendor continues to show tremendous
1.683 deraadt 55: resistance towards releasing information that would allow X.Org to support their
1.684 jasper 56: hardware properly.

1.718 nick 71: OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems,
72: including multi-chip, multi-core and/or hyperthreading designs.
1.449 grange 73: To support SMP operation, a separate SMP kernel (<tt>bsd.mp</tt>) is
1.427 saad 74: included with the installation file sets.

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