525: form of install. The instructions for doing an FTP (or other style
526: of) install are very similar; the CDROM instructions are left intact

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

567:
1.1 deraadt 568: <p>
569: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
570: release is on CD1. If your BIOS does not support booting from CD, you will need
571: to create a boot floppy to install from. To create a boot floppy write
572: <i>CD1:4.7/i386/floppy47.fs</i> to a floppy and boot via the floppy drive.
573:
574: <p>
575: Use <i>CD1:4.7/i386/floppyB47.fs</i> instead for greater SCSI controller
576: support, or <i>CD1:4.7/i386/floppyC47.fs</i> for better laptop support.
577:
578: <p>
579: If you can't boot from a CD or a floppy disk,
580: you can install across the network using PXE as described in
581: the included INSTALL.i386 document.
582:
583: <p>
584: If you are planning on dual booting OpenBSD with another OS, you will need to
585: read INSTALL.i386.
586:
587: <p>
588: To make a boot floppy under MS-DOS, use the "rawrite" utility located
589: at <i>CD1:4.7/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
590: use the
1.84 bentley 591: <a href="https://man.openbsd.org/dd.1">dd(1)</a>
1.1 deraadt 592: utility. The following is an example usage of
1.84 bentley 593: <a href="https://man.openbsd.org/dd.1">dd(1)</a>,

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

870: Note that most ports are available as packages through FTP. Updated

873: If you're interested in seeing a port added, would like to help out, or just
