Historically on HP servers (series 800 machines) ^B gets you to "PROM"
mode. It has varied on different machines whether this is enabled and
disabled by a key, or a switch on the back, or is not able to be
disabled at all.
Some newer machines (some D series, all A series, all R series) don't
have this functionality out unless an "access port" card is added to
the system. These systems do still have a TOC (Transfer of Control)
button so that dumps can be taken.
I'll dig out the part number for the access port card if anyone cares;
I don't have it to hand right now.
Regards,
Giles
