540: <ul>
541: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
542: release is on CD1. If your BIOS does not support booting from CD, you will need
543: to create a boot floppy to install from. To create a boot floppy write
544: <i>CD1:4.7/i386/floppy47.fs</i> to a floppy and boot via the floppy drive.
545:
546: <p>
547: Use <i>CD1:4.7/i386/floppyB47.fs</i> instead for greater SCSI controller
548: support, or <i>CD1:4.7/i386/floppyC47.fs</i> for better laptop support.
549:
550: <p>
551: If you can't boot from a CD or a floppy disk,
552: you can install across the network using PXE as described in
553: the included INSTALL.i386 document.
554:
555: <p>
556: If you are planning on dual booting OpenBSD with another OS, you will need to
557: read INSTALL.i386.
558:
559: <p>
560: To make a boot floppy under MS-DOS, use the "rawrite" utility located
561: at <i>CD1:4.7/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
562: use the
563: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>
564: utility. The following is an example usage of
565: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dd&sektion=1">dd(1)</a>,
566: where the device could be "floppy", "rfd0c", or

586: If you can't boot from the CD, you can create a boot floppy to install from.
587: To do this, write <i>CD2:4.7/amd64/floppy47.fs</i> to a floppy, then
588: boot from the floppy drive.

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

762: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
763: will most likely fail.

766: If your SPARC system doesn't have a floppy drive nor a CD drive, you can either

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

851: source tree, our ports tree is available via anoncvs. So, in
852: order to keep current with it, you must make the <i>ports/</i> tree
853: available on a read-write medium and update the tree with a command
854: like:
855: <p>

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