What is the equivalent of STOP-A for Solaris Intel?

Unlike Solaris on Sparc (where STOP-A gets you the OpenBoot prompt),
there is no PROM firmware to drop into on x86.
You can boot your system under kadb and then use a similar keystroke to
drop into kadb and obtain debugging information.
To boot under kadb, type eeprom boot-file=kadb and then:


  • Prior to Solaris 8, type CTRL-ALT-d to jump into kadb
  • On Solaris 8 or later, type F1-a to jump into kadb
  • At the Solaris Intel Boot Assistant prompt type "b kadb"


You can then type, for example:


$<systemdump



to force your system to panic and generate a crash dump (the equivalent of
"sync" at the ok prompt on SPARC).


The Device Configuration Assistant (DCA)
portion of the Intel boot process can be interrupted by
hitting escape (when prompted). This (I feel) is the Intel version of the
Boot Prom Monitor. Of course, all the commands cannot be equated apples to
apples because of the hardware differences!


If your console is a terminal, you can type "shift-break" or "ctrl-break"
or "ctrl-\" (ctrl-backslash)
or "<enter>" followd by "~" and "ctrl-break" on Solaris Sparc,
but this, too, is not available for Solaris Intel.
