566: Quick installer information for people familiar with OpenBSD, and the
567: use of the "disklabel -E" command. If you are at all confused when
568: installing OpenBSD, read the relevant INSTALL.* file as listed above!

570: <h3>OpenBSD/i386:</h3>
571:
1.1 deraadt 572: <p>
573: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
574: release is on CD1. If your BIOS does not support booting from CD, you will need
575: to create a boot floppy to install from. To create a boot floppy write
576: <i>CD1:4.7/i386/floppy47.fs</i> to a floppy and boot via the floppy drive.
577:
578: <p>
579: Use <i>CD1:4.7/i386/floppyB47.fs</i> instead for greater SCSI controller
580: support, or <i>CD1:4.7/i386/floppyC47.fs</i> for better laptop support.
581:
582: <p>
583: If you can't boot from a CD or a floppy disk,
584: you can install across the network using PXE as described in
585: the included INSTALL.i386 document.
586:
587: <p>
588: If you are planning on dual booting OpenBSD with another OS, you will need to
589: read INSTALL.i386.
590:
591: <p>
592: To make a boot floppy under MS-DOS, use the "rawrite" utility located
593: at <i>CD1:4.7/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
594: use the
1.84 bentley 595: <a href="https://man.openbsd.org/dd.1">dd(1)</a>
1.1 deraadt 596: utility. The following is an example usage of
1.84 bentley 597: <a href="https://man.openbsd.org/dd.1">dd(1)</a>,
1.1 deraadt 598: where the device could be "floppy", "rfd0c", or

613: <p>
614: The 4.7 release of OpenBSD/amd64 is located on CD2.
615: Boot from the CD to begin the install - you may need to adjust
616: your BIOS options first.
617: If you can't boot from the CD, you can create a boot floppy to install from.
618: To do this, write <i>CD2:4.7/amd64/floppy47.fs</i> to a floppy, then
619: boot from the floppy drive.
620:
621: <p>
622: If you can't boot from a CD or a floppy disk,
623: you can install across the network using PXE as described in the included
624: INSTALL.amd64 document.
625:
626: <p>
627: If you are planning to dual boot OpenBSD with another OS, you will need to

648: (depending on your machine) to a floppy and boot it with <i>boot
649: floppy</i>. Refer to INSTALL.sparc64 for details.
650:
651: <p>
652: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
653: will most likely fail.
654:
655: <p>
656: You can also write <i>CD3:4.7/sparc64/miniroot47.fs</i> to the swap partition on
657: the disk and boot with <i>boot disk:b</i>.
658:
