CPU power management
PC-510 user’s manual
If the required options are selected in PMISETUP.EXE, other devices,
such as the input from a serial port or the ring indicator from a modem
connected to COM2, will cause the PC-510 to resume.
First Suspend/Resume Pulse:
The on-board SVGA ceases to display video and the hard drive spins
down.
Second Suspend/Resume Pulse:
The video returns but the hard drive does not spin up again until ac-
cessed.
Note
See the Accessories appendix for connector information on the remote
suspend/resume connector.
External PMI interrupt
In case of a power failure, the power management code is capable of
properly resetting the system, saving the state of the system to disk, or
generating an INT 15h. The power failure is signaled by activation of
the external power management input, J17[1-2]. Once activated, the
system either performs a System Reset, performs a Save to Disk opera-
tion, or generates an INT 15h. These functions are enabled in a .PMI
file.
1. System Reset
The PMI file contains:
pfh-enable=Y
Enables power fail options
pfh-reset=Y

2. Save to Disk

3. INT 15h
