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

49: It can be expected to install and run with minimal difficulty on most current
50: hardware.
51: Machines using custom BIOS (such as older proprietary PC's, laptops, and some
52: specialized server machines) may cause problems.
53:
54: <p>
1.488 matthieu 55: X Window System support is available for most graphics cards, using
1.682 deraadt 56: the X.Org server. As with other free operating systems it is highly recommended
1.685 deraadt 57: that Nvidia cards are avoided since this vendor continues to show tremendous
1.683 deraadt 58: resistance towards releasing information that would allow X.Org to support their
1.684 jasper 59: hardware properly.

1.718 nick 74: OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems,
75: including multi-chip, multi-core and/or hyperthreading designs.
1.449 grange 76: To support SMP operation, a separate SMP kernel (<tt>bsd.mp</tt>) is
1.427 saad 77: included with the installation file sets.

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

1.330 miod 147: This 1.44MB floppy image contains the most common drivers.
148: It is designed to cover the most typical PC. As a general rule, you will
149: find that the missing drivers are ones which need large microcodes to run,
1.432 nick 150: such as for rare SCSI cards, gigabit ethernet cards, or RAID devices.<br>

1.330 miod 156: This 1.44MB floppy image contains some drivers that are missing from
157: Floppy A.
158: This media is designed to help people setting up modern server type systems.
159: It contains support for pretty much all the SCSI and RAID drivers, gigabit
160: ethernet cards, and such.
161: Due to space considerations, you will find that some other drivers are
1.435 deraadt 162: missing. In particular, support for most PCMCIA devices is missing, the
163: MSDOS filesystem, and for really ancient hardware devices.<br>
