System Management: OEM Boot Options
10009109-01 ATCA-9305 User’s Manual
7-11
The IPMC implements many standard IPMI commands. For example, software can use the
watchdog timer commands to monitor the system’s health. Normally, the software resets
the watchdog timer periodically to prevent it from expiring. The IPMI specification allows
for different actions such as reset, power off, and power cycle, to occur if the timer expires.
The watchdog’s ‘timer use’ fields can keep track of which software (Operating System, Sys-
tem Management, etc.) started the timer. Also, the time-out action and ‘timer use’ infor-
mation can be logged automatically to the System Event Log (SEL) when the time-out
occurs. Refer to the IPMI specification (listed in
Ta bl e 1- 2) for details about each command’s
request and response data. The IPMC also implements ATCA commands, see the ATCA Base
Specification (PICMG 3.0).
OEM BOOT OPTIONS
The Set System Boot Options and Get System Boot Options commands provide a means to
set/retrieve the boot options. The IPMI specification defines a set of standard boot option
parameters. In addition, the specification includes a range of numbers (96-127) for OEM
extensions. Emerson utilizes this area for OEM function extensions, such as boot bank selec-
tion and POST configuration. The following table describes these extensions:
