456: Quick installer information for people familiar with OpenBSD, and the

458: installing OpenBSD, read the relevant INSTALL.* file as listed above!

461:
1.1 deraadt 462: <p>
463: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
464: release is on CD1. If your BIOS does not support booting from CD, you will need
465: to create a boot floppy to install from. To create a boot floppy write
466: <i>CD1:5.2/i386/floppy52.fs</i> to a floppy and boot via the floppy drive.
467:
468: <p>
469: Use <i>CD1:5.2/i386/floppyB52.fs</i> instead for greater SCSI controller
470: support, or <i>CD1:5.2/i386/floppyC52.fs</i> for better laptop support.
471:
472: <p>
473: If you can't boot from a CD or a floppy disk,
474: you can install across the network using PXE as described in
475: the included INSTALL.i386 document.
476:
477: <p>
478: If you are planning on dual booting OpenBSD with another OS, you will need to
479: read INSTALL.i386.
480:
481: <p>
482: To make a boot floppy under MS-DOS, use the "rawrite" utility located
483: at <i>CD1:5.2/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
484: use the
1.89 bentley 485: <a href="https://man.openbsd.org/dd.1">dd(1)</a>
1.1 deraadt 486: utility. The following is an example usage of
1.89 bentley 487: <a href="https://man.openbsd.org/dd.1">dd(1)</a>,
1.1 deraadt 488: where the device could be "floppy", "rfd0c", or

504: The 5.2 release of OpenBSD/amd64 is located on CD2.
505: Boot from the CD to begin the install - you may need to adjust
506: your BIOS options first.
507: If you can't boot from the CD, you can create a boot floppy to install from.
508: To do this, write <i>CD2:5.2/amd64/floppy52.fs</i> to a floppy, then
509: boot from the floppy drive.
510:
511: <p>
512: If you can't boot from a CD or a floppy disk,
513: you can install across the network using PXE as described in the included
514: INSTALL.amd64 document.

717: described <a href="anoncvs.html">here</a>.
718: Using these files
719: results in a much faster initial CVS update than you could expect from

746: if you know nothing about ports
747: at this point. This text is not a manual of how to use ports.
748: Rather, it is a set of notes meant to kickstart the user on the
749: OpenBSD ports system.
750: <p>
751: The <i>ports/</i> directory represents a CVS (see the manpage for
1.92 bentley 752: <a href="https://man.openbsd.org/cvs.1">cvs(1)</a> if
1.1 deraadt 753: you aren't familiar with CVS) checkout of our ports. As with our complete
754: source tree, our ports tree is available via anoncvs. So, in
755: order to keep current with it, you must make the <i>ports/</i> tree
756: available on a read-write medium and update the tree with a command
757: like:
1.89 bentley 758: <blockquote><pre>
1.91 deraadt 759: # <kbd>cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_5_2</kbd>
1.89 bentley 760: </pre></blockquote>
1.1 deraadt 761: <p>
762: [Of course, you must replace the local directory and server name here
763: with the location of your ports collection and a nearby anoncvs
764: server.]
765: <p>
1.91 deraadt 766: Note that most ports are available as packages on our mirrors. Updated
1.1 deraadt 767: packages for the 5.2 release will be made available if problems arise.
768: <p>
769: If you're interested in seeing a port added, would like to help out, or just
770: would like to know more, the mailing list
771: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
