CPU power management
TEST.PMI:
pmi-enable=Y
Enables the power management
save-to-disk=Y
Enables save to disk feature
pfh-enable=Y
Enables power fail option
pfh-reset=N
Disables power fail reset
3. Load the .PMI file changes by including the .PMI file on the PMISETUP
command line. PMISETUP is located in the \UTILS directory:
PC500 C:\> PMISETUP TEST.PMI
4. Hardware reset the system for the PMISETUP options to take effect.
The PC-500 system is now ready to Save to Disk.
5. Initiate a PMI input signal at J10[1-2]. Refer to the IRQ routing and
opto IRQs chapter for the PMI connection and signal generation.
Note
The default signals at J10 are [1-2] PMI and [3-4] SUSPEND/RESUME
signal. These signals may be changed by reprogramming the IRQ ma-
trix. See the IRQ routing and opto irqs chapter for more information on
the IRQ matrix.
6. The system now performs a contextual save, saving all relevant informa-
tion to the special disk partition.
7. The system will respond with “Please turn off your computer.” Power
down the system. The CPU enters SUSPEND mode. The validity of the
system context on the hard disk is identified by marking a bit in the
configuration EEPROM.
8. When the system is powered on, the validity of the context is checked in
EEPROM. If valid, the system’s context is restored to the system
memory and devices, back to where it was before the PMI signal was
generated.

Power management configuration
The power management functions can be globally enabled or disabled in
CMOS. The PC-500 SETUP.EXE and PMISETUP.EXE utilities provide
an option for enabling or disabling power management.
Enabling power management
Whichever utility, SETUP or PMISETUP, is configured and saved (or
loaded) last, that configuration is used for enabling or disabling power
management. In other words, if the power management option is dis-
abled in SETUP and then later a .PMI file which shows pmi-enable = Y is
loaded with PMISETUP, the power management option in SETUP will
now show power management as being enabled.
In PC-500 SETUP, the following options are available:
Power Management:
ENABLED or DISABLED
DOZE Clock (Slow, Stop):
SLOW or STOP
Time Updated After Suspend:
ENABLED or DISABLED
