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>
1.29 ! deraadt 24: <li>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.
