Booting OpenBSD
The install image will then load, provided floppy boot is enabled in your BIOS. If you want to boot from CD, you must go into your system's BIOS and set the boot options to allow booting from CD.Some older BIOSes do not have this option, and you must use a floppyfor booting your installation image. Don't worry though; even if you boot from floppy you can still installfrom the CD.
You can also install by booting bsd.rd from anexisting OpenBSD partition, or over the network using the PXE boot process. Booting sparc/sparc64NOTE:On the sparc64 platform, only the SBusmachines (Ultra 1, Ultra 2) are bootable from floppy.
To boot from floppy, place the floppy disk with the OpenBSD installation image on it into the floppy drive. Then use the following command to boot from the floppy:
ok boot floppy
To boot from CD-ROM, place the OpenBSD CD-ROM disk into the drive. If your Sun only has one CD-ROM drive, then just go to the boot prompt, where you can 'boot cdrom':
ok boot cdrom
Of course, this will only work in new command mode. If you are at the old command mode prompt (a right arrow), type 'n' for the new command mode. (If you are using an old sparc that is pre-sun4c, you probably don't have a new command mode.In this case, you need to experiment.) If you have multiple CD-ROM devices, you need to boot from the correct one.Try probe-scsi from the new command mode.
ok probe-scsi
