2.1 .lDRAM Module Insertion
The SIMMs must be seated on the sockets as firmly as possible, and, be-
cause of the fragility of the slot, you must be careful when inserting or re-
moving the module.
Align the module so that the pin 1 marking and comer notch of the module
1. correspond to the SIMM socket pin 1 marking at the rear of the board. The module can fit in the socket one way only. Do not force it!
2.
Push the module against the clip arms with your thumbs until a “click­ing” sound is heard; the little plastic tabs appear in the latching holes on the RAM module board, and the clip arms fully grab the module board.
2.1.2 DRAM Module Removal
If possible, use a SIMM extraction tool; otherwise use the following method:

Carefully use your thumbs to bend outward the plastic tab ends on both sides of the slot.
2. The RAM module board will be automatically ejected off the clip arms.
3.
Take it out of the socket.
4. Repeat steps 1 through 3 to release the other RAM modules.

BIOS Errors and Messages
After entering the SETUP choices, the system will reboot. The SETUP summary and system information will appear on screen along with mes­sages. These may include ERROR messages concerning the system or SETUP.
Phoenix BIOS performs various diagnostic tests at the time the system is turned on. Whenever an error is encountered during these tests, error codes
will be displayed on the screen. The following table lists the error codes
and their respective meanings.

Power Management Function
The Power Management Function included in the
SA486P
AIO-U is an ar­chitecture designed to allow programming of the monitored system events of six devices. It is also aimed at reducing the system’s power consumption during idle stages.
5.1 How Does Power Management Function Work?
Power Management Function implements a PMU (Power Management Unit) handler that monitors the interrupt signals of different devices
(i.e. ,keyboard.floppy the interrupt events detector.Once interrupt fied by the user,are not accessed from the devices to the PMU handler,the system will automatically be put into sleep mode.The diagram below de­scribes the operation.
