CPU power management PC-510 user’s manual
However, if power consumption is not a major concern for your system
when using the video accelerator function, Octagon Systems strongly
recommends that you disable power management and install W2[3-4].
This enables the CPU to operate at full clock speed (133 MHz) and still
maintain the PC-510’s temperature performance range between –40°C
and +45°C.

PMISETUP
The PMISETUP program allows modification of the 82C465 registers
and optionally the serial EEPROM data associated with the 82C465/
CMOS registers. The command line format for the PMISETUP program
is as follows:
PMISETUP inputfilename [/SHOWALL] [/DEFAULT] [/P] [/?]
PMISETUP will parse a file using KEYWORD=nn[type] options. One
keyword can be specified per line, characters after a semicolon “;” will be
regarded as comments. Blank lines are ignored. If multiple lines contain
the same keyword, the last value will be used. Keywords and values are
not case sensitive.
A sample input file, TEST.PMI, is as follows:
pmi-enable=Y Disables/enables the power management code
doze-delay=2 Sets DOZE time-out to 2 seconds before standby
hdd-to=10 Sets the hard drive time-out to 10 minutes.
Load the .PMI file changes by including the .PMI file on the PMISETUP
command line. PMISETUP is located in the \UTILS directory:
PC510 C:\> PMISETUP TEST.PMI
The output from PMISETUP will show all selectable options and their
current values even when not specified when the /SHOWALL option is
used.
When the /DEFAULT option is used, default settings are first loaded
before the keywords are parsed. Refer to the default PMI configuration
later in this chapter.
