questions about auto-boot? and watchdog-reboot? prom variables

Hello,

I have two questions:
1) We have a requirement that our machines will only go to an "ok" prompt when
the power comes on after a poweroutage. I would still like to be able to do
a normal reboot of the machine. I originally thought that if you set the
eeprom variable "auto-boot?" to false, I would not be able to do a normal
reboot of the machine. I tested setting the prom variable "auto-boot?" to
false on a sparc4, and I was sucessful in rebooting it. Is this the expected
behavior when setting "auto-boot?" to false, so my original understanding was
incorrect? Does anyone know if this works the same for all Suns, like
Sparc4,5, 10, E250, Ultra1?

2) Does anyone have any recommendations for or against setting the eeprom
variable "watchdog-reboot?" to true? I'm concidering setting this to true so
the machine will reboot if there is a watchdog reset.

If I have "auto-boot?" set to false, "watchdog-reboot?" to true, and a
watchdog reset occurs, will the system just stay at the ok prompt because the
system did a reset. Will the "auto-boot?" variable have precidence over the
"watchdog-reboot?" variable? (Does that make any sense?)

Thanks!
Nicole
