osd(1M) provides software support for OpenBoot PROM. It provides an SMS event-based interface to setkeyswitch(1M) for laying out IDPROM, NVRAM and REBOOTARGS information prior to domain bring up.

osd also receives mailbox commands from OpenBoot PROM. These mailbox commands are acted upon and a result is returned to OpenBoot PROM. Commands include get-time-of-day, set-time-of-day, get-idprom, get-nvram-data, set-nvram-data, get-reboot-args, set-reboot-args, and do-tunnel-switch. There is one instance of osd on the system controller (SC) shared between all domains.

This daemon is automatically started by ssd(1M). Do not start it manually from the command line.
