Chapter4 Power Management
539 mainboard provides four power management modes for reducing power consumption : On, Doze, Standby, and Suspend.
539 mainboard also provide EPMI and power supply power down
connector to enchanced power management.
Power Management Modes Description
ON mode. The ON mode is the normal operating mode of the
PC system. In this mode, the doze timer (15 sec to 512 min)
starts counting if no activity is taking place and the programmable time-out period has expired. The system will enter to doze
mode. The types of activities monitored include Keyboard Controller, VGA, IDE, COM port, LPT port, Floppy, PCI master, ISA
master, DMA, and one programmable memory region and one
programable I/O region.
DOZE mode. In this mode, CPU frequency is slowed to 1/2 of
normal frequency and the STANDBY timer (2 min to 512 min)
starts counting if no activities is taking place. The activities monitored are the same as in ON mode.
STANDBY mode. CPU and system future more reduce to a lower
frequency. In this mode, the SUSPEND timer (2 min to 512 min)
starts counting if no activities is taking place. The activities monitored are the same as in ON mode.
SUSPEND mode. In this mode,539 mainboard will stop the CPU
clock (0MHz), slow down the system clock, power down the secondary cache. Auto-wake-up, including keyboard, mouse, EPMI
button, and modem, and so forth, is programmable.

Install Utility for PCI-Bus IDE Controller
The INSTALL4.EXE utility can detect the speeds of the hard disks
which are attached on the controller automatically, and it also can
install drivers for you. Please follow the steps below to excute the
program first.
1 Insert the diskette in a floppy disk drive, and close the
drive door.
2 At the command prompt, type the drive letter of the
floppy drive you are using, followed by colon(:), and
then press ENTER.
3 Type INSTALL4, and then press ENTER.
4 Follow the instructions on the screen to detect hard
disk(s) speed and install driver(s).
This program may get an incorrect speed in some few cases. At
that time, please install the drivers manually to reduce the drive
speed step by step until the system boots or becomes stable. Please
remember the current speed, and minus 2 if FIFO is enabled; or
minus 4 if FIFO is disabled. This way, you can find the optimized
performance speed of your system. If it is possible, please burn-in
your system with IDE operations to make sure the stability of your
system.

OS2\UMC1S506.ADD into the OS2\BOOT subdirectory of your system for OS/2 V3.0.
2. Check if the following line exists in the CONFIG.SYS
file.
BaseDev = IBM1S506.ADD
If the statement exists, please delete it or add “REM” in
front of it.
3. Add the following statement to your CONFIG.SYS
file.
BaseDev = UMC1S506.ADD [/A:<0 or 1> /IRQ:<irq> /U:<0 or
1> /S:<speed> /F /NF]
where
speed : drive speed setting from 0 to 17 ( 0 the lowest )
F : enable FIFO for drive
NF : disable FIFO for drive
IRQ : 10 or 12 or 15
For instance, the user wants to load UMC1S506.ADD with drive
0, speed 6, FIFO disabled, and drive 1, speed 11, FIFO enabled
which are attached on Adapter 0. Add the following statement to
your CONFIG.SYS file.
BaseDev = UMC1S506.ADD /A:0 /U:0 /S:6 /NF /U:1 /S:11 /F
You don’t need to specify drive speed parameters usually, be-
cause the device driver is reconfigured for the optimal speed setting.

initialized key system components. When a POST routine completes, a code is written to I/O port address 80h. Display this
code by attaching diagnostic equipment to port 80h.
The following POST checkpoint codes are valid for 539
mainboard's WinBIOS.
