System timers
The system timers define the delays associated with power state transi-
tions in the system. Three managed system power modes (in addition to
full on) are supported, DOZE, STANDBY, and SUSPEND. Individual
timers for system devices, including floppy disk, hard disk, and serial ports
are also provided. The timers are described below:
In a .PMI file, the following options are available:
fdd-to=xx
Sets the on-card (LPT1) floppy disk drive time-out
value (x=0-31 minutes)
hdd-to=xx
Sets the hard drive time-out value (x=0-31 minutes)
COM1-to=xx
Sets the COM1 time-out value (x=0-31 minutes)
COM2-to=xx
Sets the COM2 time-out value (x=0-31 minutes)
doze-delay=x
Sets DOZE time-out before STANDBY(x=0,2,8 seconds)
standby-delay=xx Sets delay time before STANDBY (x=0-31 minutes)
suspend-delay=xx Sets delay time before SUSPEND (x=0-31 minutes)
Doze timer enable and resets
The DOZE mode may be selected to be a SLOW clock or STOP clock mode
and is determined in power management SETUP. Numerous sources may
reset the DOZE timer, preventing entry to DOZE mode. The BIOS as-
sumes that video, floppy, hard disk, and keyboard accesses should all reset
the DOZE timer. In addition, various interrupts can be configured to reset
the timer. DOZE timer 0 is used for all DOZE reset selections. DOZE
timer 1 is used for the special case of the timer interrupt in a STOP clock
mode. In this mode, DOZE timer 1 is configured for a 4 millisecond time-
out, with only IRQ0 configured to reset DOZE timer 1. This allows the
CPU to resume normal operation for 4 mS on each IRQ0 in order to main-
tain the time of day.
In the PC-510 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
