1.1 deraadt 20:
1.3 fn 21: <p>
1.26 deraadt 22: The i386 port has quite a few architecture specific changes from the
1.2 deraadt 23: NetBSD/i386 port, but the major ones are:
1.1 deraadt 24: <ul>
1.30 michaels 25: <li>Also runs on machines with 512MB of ram or more, does not crash.
1.3 fn 26: <li>the addition of ISA bounce buffer support so that ISA scsi cards (ie.
1.11 deraadt 27: Adaptec 1542) can be used in machines with more than 16MB of memory.
1.4 deraadt 28: <li>The same one GENERIC kernel works on all machines, whether it has
1.11 deraadt 29: BusLogic or Adaptec scsi cards.
1.4 deraadt 30: <li>some APM and PCMCIA support (3c589, NE2000-clone, and COM ports)
31: <li>some DDB improvements
32: <li>OPTI mcd support
33: <li>ATAPI cdrom support
34: <li>P5/P6 improved NTP support
35: <li>pccons has userland replaceable keymaps, and screen blanking
36: <li>boot "-a" support like other ports (asks for root partition)
1.11 deraadt 37: <li>floppy disk formatting
1.7 deraadt 38: <li>Cyclades Cyclom serial driver
1.11 deraadt 39: <li>faster (assembly) IP checksumming (typically 20% faster, up to 62% faster
40: in some cases)
1.18 deraadt 41: <li>vmstat -i prints interrupt information.
42: <li>latest rev of adaptec 2940 driver from FreeBSD
1.11 deraadt 43: <li>supports "ep* at port ? irq ?"
1.12 deraadt 44: <li>faster i386-specific `pccom' device driver.
1.19 deraadt 45: <li>/dev/pctr pseudo-device & program for accessing the Pentium and PentiumPro
1.18 deraadt 46: performance counters.
1.15 deraadt 47: <li>Fixed major i386 kernel interrupt race.
48: <li>Fixed UCONSOLE security hole without breaking xconsole.
49: <li>Much faster i387-specific libm available for those who want the option.
1.17 deraadt 50: <li>ISA Plug-and-Play support
1.21 deraadt 51: <li>the GPL FP emulator from Linux/Freebsd, for users who want to use it.
52: Much better!
1.28 deraadt 53: <li>Prefer partition type 166, so that OpenBSD can co-reside on the same
54: disk as a 386BSD/NetBSD/FreeBSD install.
55: <li>Attempt to fault in a ptp; this avoids two ptp panic cases.
56: <li>RAW_PART is now 'c', not 'd'. It should start at 0, and cover your whole
57: disk.
1.29 deraadt 58: <li>Updated ncr driver, much more performance.
59: <li>3c59x and 3c9xx cards work.
60: <li>Can mount DOS file systems with cluster size > 16KB.
1.42 kstailey 61: <li>Support for M$ IntelliMouse as a 3-button PS/2 mouse.
1.1 deraadt 62: </ul>

1.54 deraadt 65: <h3><font color=#0000e0>Installation with Other Operating Systems:</font></h3>
1.46 deraadt 66: The OpenBSD/i386 port can be installed to share the system disks with
1.32 grr 67: other operating systems such as MSDOS, Windows or Linux using the MSDOS
68: MBR/partition scheme and an optional boot selector. Everyday operation is
69: trouble free, but setup requires care and Windows '95 installation is known
70: to be careless about pre-existing MBR/partition information.
71: See the Installation Notes for more details.
1.34 johns 72:
1.32 grr 73: <p>
1.54 deraadt 74: <h3><font color=#0000e0>Binary compatibility with other Operating Systems:</font></h3>
1.46 deraadt 75: The OpenBSD/i386 port can run Linux, FreeBSD, BSD/OS,
1.44 deraadt 76: SVR4 (including Solaris), and IBCS2 binaries.
77:
78: <p>
1.54 deraadt 79: <h3><font color=#0000e0>Supported Hardware:</font></h3>
1.46 deraadt 80: The OpenBSD/i386 port works across a broad range of standard PC's and clones,
1.32 grr 81: with a wide variety of processors and I/O bus architecures. It can be expected
1.53 todd 82: to install and run with minimal difficulty on most current products.
1.32 grr 83: The cases where problems may be encountered are typically older proprietary
84: PC's, Laptops or specialized server boxes that rely on a custom BIOS to paper
85: over implementation differences.
1.34 johns 86:
1.32 grr 87: <p>
88: OpenBSD does not currently support multiple processors, but will run using
89: one processor on a multi-processor system board.
1.34 johns 90:

! 95: as the AMD K5 series and Cyrix cpu family. Everything
! 96: that is a clone of the 386 or up should work fine. The
! 97: only cpu that is known to work poorly (due to flawed
! 98: motherboard designs) is the Cyrix 386DLC.
