539: <ul>
540: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
541: release is on CD1. If your BIOS does not support booting from CD, you will need
542: to create a boot floppy to install from. To create a boot floppy write
543: <i>CD1:4.7/i386/floppy47.fs</i> to a floppy and boot via the floppy drive.
544:
545: <p>
546: Use <i>CD1:4.7/i386/floppyB47.fs</i> instead for greater SCSI controller
547: support, or <i>CD1:4.7/i386/floppyC47.fs</i> for better laptop support.
548:
549: <p>
550: If you can't boot from a CD or a floppy disk,
551: you can install across the network using PXE as described in
552: the included INSTALL.i386 document.
553:
554: <p>
555: If you are planning on dual booting OpenBSD with another OS, you will need to
556: read INSTALL.i386.
557:
558: <p>
559: To make a boot floppy under MS-DOS, use the "rawrite" utility located
560: at <i>CD1:4.7/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
561: use the
562: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
563: utility. The following is an example usage of
564: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,

586: To do this, write <i>CD2:4.7/amd64/floppy47.fs</i> to a floppy, then

748: If your SPARC system does not have a CD drive, you can alternatively boot from floppy.
749: To do so you need to write <i>floppy47.fs</i> to a floppy.
750: For more information see <a href="faq/faq4.html#MkFlop">FAQ 4.3.1</a>.
751: To boot from the floppy use one of the two commands listed below,
752: depending on the version of your ROM.

754: <ul><pre>
755: ok <strong>boot floppy</strong>
756: or

761: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
762: will most likely fail.
763:
764: <p>
765: If your SPARC system doesn't have a floppy drive nor a CD drive, you can either

808: Both of these trees are a regular CVS checkout. Using these trees it
809: is possible to get a head-start on using the anoncvs servers as
810: described <a href="anoncvs.html">here</a>.
811: Using these files

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

849: you aren't familiar with CVS) checkout of our ports. As with our complete
850: source tree, our ports tree is available via anoncvs. So, in
851: order to keep current with it, you must make the <i>ports/</i> tree
852: available on a read-write medium and update the tree with a command
853: like:
854: <p>
855: <ul><pre>
1.26 deraadt 856: # <strong>cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_4_7</strong>

858: <p>
859: [Of course, you must replace the local directory and server name here
860: with the location of your ports collection and a nearby anoncvs
861: server.]
862: <p>
863: Note that most ports are available as packages through FTP. Updated
864: packages for the 4.7 release will be made available if problems arise.
865: <p>
866: If you're interested in seeing a port added, would like to help out, or just
867: would like to know more, the mailing list ports@openbsd.org is a good
868: place to know.
