Notes on OpenBoot PROM

If you execute the sendbreak(8) command after the OpenBoot PROM banner

the following error message is output. In this case, the boot command becomes
unable to be executed.
FATAL: OpenBoot initialization sequence prematurely
terminated.
In this case, set the OpenBoot PROM environment variable auto-boot? to false at
the ok prompt, and execute the reset-all command. When OpenBoot PROM is

characters that can be set is 254.
If you want to set a string of 255 or more characters in an OpenBoot PROM

Solaris environment. Note that, however, the maximum number of characters is
1024.

Server for SPARC disks and logical domains to which no network is assigned. To

device aliases disk and net by using the OpenBoot PROM nvalias command.
