OpenBoot Emergency Procedures
The introduction of universal serial bus (USB) keyboards with the newest Sun
systems has made it necessary to change some of the OpenBoot emergency
procedures. Specifically, the
Stop-N
,
Stop-D
, and
Stop-F
commands that were
available on systems with non-USB keyboards are not supported on systems that use
USB keyboards, such as the Sun Fire server. If you are familiar with the earlier (non-
USB) keyboard functionality, this section describes the analogous OpenBoot
emergency procedures available in newer systems that use USB keyboards.
