18: <h3><strong>History and Status:</strong></h3>
1.1 deraadt 19:
1.3 fn 20: <p>
1.26 deraadt 21: The i386 port has quite a few architecture specific changes from the
1.2 deraadt 22: NetBSD/i386 port, but the major ones are:
1.1 deraadt 23: <ul>
1.30 michaels 24: <li>Also runs on machines with 512MB of ram or more, does not crash.
1.3 fn 25: <li>the addition of ISA bounce buffer support so that ISA scsi cards (ie.
1.11 deraadt 26: Adaptec 1542) can be used in machines with more than 16MB of memory.
1.4 deraadt 27: <li>The same one GENERIC kernel works on all machines, whether it has
1.11 deraadt 28: BusLogic or Adaptec scsi cards.
1.4 deraadt 29: <li>some APM and PCMCIA support (3c589, NE2000-clone, and COM ports)
30: <li>some DDB improvements
31: <li>OPTI mcd support
32: <li>ATAPI cdrom support
33: <li>P5/P6 improved NTP support
34: <li>pccons has userland replaceable keymaps, and screen blanking
35: <li>boot "-a" support like other ports (asks for root partition)
1.11 deraadt 36: <li>floppy disk formatting
1.7 deraadt 37: <li>Cyclades Cyclom serial driver
1.11 deraadt 38: <li>faster (assembly) IP checksumming (typically 20% faster, up to 62% faster
39: in some cases)
1.18 deraadt 40: <li>vmstat -i prints interrupt information.
41: <li>latest rev of adaptec 2940 driver from FreeBSD
1.11 deraadt 42: <li>supports "ep* at port ? irq ?"
1.12 deraadt 43: <li>faster i386-specific `pccom' device driver.
1.19 deraadt 44: <li>/dev/pctr pseudo-device & program for accessing the Pentium and PentiumPro
1.18 deraadt 45: performance counters.
1.15 deraadt 46: <li>Fixed major i386 kernel interrupt race.
47: <li>Fixed UCONSOLE security hole without breaking xconsole.
48: <li>Much faster i387-specific libm available for those who want the option.
1.17 deraadt 49: <li>ISA Plug-and-Play support
1.21 deraadt 50: <li>the GPL FP emulator from Linux/Freebsd, for users who want to use it.
51: Much better!
1.28 deraadt 52: <li>Prefer partition type 166, so that OpenBSD can co-reside on the same
53: disk as a 386BSD/NetBSD/FreeBSD install.
54: <li>Attempt to fault in a ptp; this avoids two ptp panic cases.
55: <li>RAW_PART is now 'c', not 'd'. It should start at 0, and cover your whole
56: disk.
1.29 deraadt 57: <li>Updated ncr driver, much more performance.
58: <li>3c59x and 3c9xx cards work.
59: <li>Can mount DOS file systems with cluster size > 16KB.
1.1 deraadt 60: </ul>

1.32 grr 62: <p>
1.34 johns 63: <h3>Installation with Other Operating Systems:</h3>
1.32 grr 64: The OpenBSD i386 port can be installed to share the system disks with
65: other operating systems such as MSDOS, Windows or Linux using the MSDOS
66: MBR/partition scheme and an optional boot selector. Everyday operation is
67: trouble free, but setup requires care and Windows '95 installation is known
68: to be careless about pre-existing MBR/partition information.
69: See the Installation Notes for more details.
1.34 johns 70:
1.32 grr 71: <p>
1.34 johns 72: <h3>Supported Hardware:</h3>
1.32 grr 73: The OpenBSD i386 port works across a broad range of standard PC's and clones,
74: with a wide variety of processors and I/O bus architecures. It can be expected
75: to install and run with minimal diffculty on most current products.
76: The cases where problems may be encountered are typically older proprietary
77: PC's, Laptops or specialized server boxes that rely on a custom BIOS to paper
78: over implementation differences.
1.34 johns 79:
1.32 grr 80: <p>
81: OpenBSD does not currently support multiple processors, but will run using
82: one processor on a multi-processor system board.
1.34 johns 83:
1.31 deraadt 84: <p>
85: <ul>
1.32 grr 86: <li> All mainstream i386 architecture CPU chips, including 386, 486, Pentium, Pentium-Pro and compatibles such as the AMD K5 series.
87: <li> Basically all standard ISA, VLB, PCI, or PCMCIA bus based machines.
1.31 deraadt 88: <li> Floppy controllers.
89: <li> MFM, ESDI, IDE, and RLL hard disk controllers.

94: <li> Adaptec AIC-6260 and AIC-6360 based boards, including the Adaptec AHA-152x and the SoundBlaster SCSI host adapter. (Note that you cannot boot from these boards if they do not have a boot ROM; only the AHA-152x and motherboards using this chip are likely to be bootable, consequently.)
1.36 ! johns 95: <li> Adaptec AIC-7770-based SCSI host adapters (including the Adaptec AHA-274x, AHA-284x families).
1.34 johns 96: <li> Adaptec AHA-294x[W] cards and some onboard PCI designs using the AIC7870 chip. This driver does *not* currently work with non-PCI AIC-7xxx boards or the Adaptec 3940.
97: <li> Buslogic 54x (Adaptec AHA-154x clones; driver on kcadp floppy)

201:
202: Drivers for hardware marked with "[*]" are NOT included on the
203: distribution floppies. Except as noted above, all other drivers are
204: present on both kernel-copy disks. Also, at the present time, the
205: distributed kernels support only one SCSI host adapter per machine.
206: OpenBSD normally allows more, though, so if you have more than one, you
207: can use all of them by compiling a custom kernel once OpenBSD is
208: installed.
209:
210: Support for devices marked with "[+]" IS included in the "generic" kernels,
211: although it is not in the kernel on the installation floppy.
