310: "atomically" create the listening mux socket by binding it on a

312: succeeded. This allows the mux clients to determine that the server
313: socket is either ready or stale without races. Stale server sockets

511: <ul>
512: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
513: release is on CD1. If your BIOS does not support booting from CD, you will need
514: to create a boot floppy to install from. To create a boot floppy write
515: <i>CD1:4.9/i386/floppy49.fs</i> to a floppy and boot via the floppy drive.
516:
517: <p>
518: Use <i>CD1:4.9/i386/floppyB49.fs</i> instead for greater SCSI controller
519: support, or <i>CD1:4.9/i386/floppyC49.fs</i> for better laptop support.
520:
521: <p>
522: If you can't boot from a CD or a floppy disk,
523: you can install across the network using PXE as described in
524: the included INSTALL.i386 document.
525:
526: <p>
527: If you are planning on dual booting OpenBSD with another OS, you will need to
528: read INSTALL.i386.
529:
530: <p>
531: To make a boot floppy under MS-DOS, use the "rawrite" utility located
532: at <i>CD1:4.9/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
533: use the
534: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
535: utility. The following is an example usage of
536: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,
537: where the device could be "floppy", "rfd0c", or

557: If you can't boot from the CD, you can create a boot floppy to install from.
558: To do this, write <i>CD2:4.9/amd64/floppy49.fs</i> to a floppy, then
559: boot from the floppy drive.

692: <p>
693: On other systems, or if your machine doesn't have a CD drive, you can
694: setup a DHCP/tftp network server, and boot using "bootp()/bsd.rd.IP##" using
695: the kernel matching your system type.

720: If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
721: To do so you need to write <i>floppy49.fs</i> to a floppy.
722: For more information see <a href="faq/faq4.html#MkFlop">FAQ 4.3.2</a>.
723: To boot from the floppy use one of the two commands listed below,
724: depending on the version of your ROM.
725:
726: <ul><pre>
727: ok <strong>boot floppy</strong>
728: or
729: > <strong>b fd()</strong>
730: </pre></ul>
731:
732: <p>
733: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
734: will most likely fail.
735:
736: <p>
737: If your SPARC system doesn't have a floppy drive nor a CD drive, you can either
738: setup a bootable tape, or install via network, as told in the
739: INSTALL.sparc file.

780: Both of these trees are a regular CVS checkout. Using these trees it
781: is possible to get a head-start on using the anoncvs servers as
782: described <a href="anoncvs.html">here</a>.
783: Using these files
784: results in a much faster initial CVS update than you could expect from

815: Rather, it is a set of notes meant to kickstart the user on the

817: <p>
818: The <i>ports/</i> directory represents a CVS (see the manpage for

821: you aren't familiar with CVS) checkout of our ports. As with our complete
822: source tree, our ports tree is available via anoncvs. So, in
823: order to keep current with it, you must make the <i>ports/</i> tree
824: available on a read-write medium and update the tree with a command
825: like:
826: <p>
827: <ul><pre>
828: # <strong>cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_4_9</strong>
829: </pre></ul>
830: <p>
831: [Of course, you must replace the local directory and server name here
832: with the location of your ports collection and a nearby anoncvs
833: server.]
834: <p>
835: Note that most ports are available as packages through FTP. Updated
836: packages for the 4.9 release will be made available if problems arise.
837: <p>
838: If you're interested in seeing a port added, would like to help out, or just
839: would like to know more, the mailing list ports@openbsd.org is a good
840: place to know.
