7 FORCE OpenBoot Enhancements
The OpenBoot ported to the SPARC/CPCI-52x(G) is based upon Open-
Boot V3.10 obtained from Sun Microsystems. This section describes the
enhancements to the standard OpenBoot firmware that have been done
for the SPARC/CPCI-52x(G). Examples are given when it seems neces-
sary to convey the usage of a particular word or a group of words.
Note: OpenBoot is subject to changes. Some features are only
available with specific versions of the software. Features not
available on all OpenBoot versions are marked with the version
given, e.g. ... (OpenBoot 3.10.4 and above) ... . For information on the
latest OpenBoot version and how to upgrade refer to the SMART
service accessible via the FORCE COMPUTERS World Wide Web
site.
Base information For a description of standard OpenBoot 3.x firmware features, see the
OpenBoot 3.x Manual Set.
Besides the commands already provided by the standard OpenBoot firm-
ware, the OpenBoot firmware available on the SPARC/CPCI-52x(G) in-
cludes further words for
• accessing and configuring system specific components (see
section 7.1 “System Configuration” on page 102),
• accessing and programming available flash EPROMs (see section 7.2
“Flash EPROM Support” on page 110).
For information on additional hardware dependencies, see section 7.3
“Hardware Dependencies” on page 116.
Notation In general, each word is described using the following notation:
name ( stack-comment ) description
The name field identifies the name of the word being described.
The stack-comment notation which is enclosed in parentheses de-
scribes the stack parameters passed to and returned from a word. It
shows the effect of the word on the evaluation stack. The parameters
passed and returned to the word are separated by the “—” within the
stack-comment:
parameters before execution — parameters after execution
The description body describes the semantics of the word. It also con-
veys the purpose and effect of the particular word.
