! 456:
1.1 deraadt 457: <p>
458: Play with your BIOS options to enable booting from a CD. The OpenBSD/i386
459: release is on CD1. If your BIOS does not support booting from CD, you will need
460: to create a boot floppy to install from. To create a boot floppy write
461: <i>CD1:5.2/i386/floppy52.fs</i> to a floppy and boot via the floppy drive.
462:
463: <p>
464: Use <i>CD1:5.2/i386/floppyB52.fs</i> instead for greater SCSI controller
465: support, or <i>CD1:5.2/i386/floppyC52.fs</i> for better laptop support.
466:
467: <p>
468: If you can't boot from a CD or a floppy disk,
469: you can install across the network using PXE as described in
470: the included INSTALL.i386 document.
471:
472: <p>
473: If you are planning on dual booting OpenBSD with another OS, you will need to
474: read INSTALL.i386.
475:
476: <p>
477: To make a boot floppy under MS-DOS, use the "rawrite" utility located
478: at <i>CD1:5.2/tools/rawrite.exe</i>. To make the boot floppy under a Unix OS,
479: use the
1.89 ! bentley 480: <a href="https://man.openbsd.org/dd.1">dd(1)</a>

500: Boot from the CD to begin the install - you may need to adjust
501: your BIOS options first.
502: If you can't boot from the CD, you can create a boot floppy to install from.
503: To do this, write <i>CD2:5.2/amd64/floppy52.fs</i> to a floppy, then
504: boot from the floppy drive.
505:
506: <p>
507: If you can't boot from a CD or a floppy disk,
