The main memory consists of two lockable DIMM sockets. It can be used standard 3.3V SDRAM
modules, which correspond to the Intel specification PC100 or PC133.
Note for plug-in: first socket DIMM1, then socket DIMM2.
Per socket a maximum of 512 Mbytes SDRAM are possible.
Since the chipset supports 256-Mbit DRAMs at the most, a 512-MB module must consist of two
banks each based on 256 Mbit.
During plug-in of the modules please pay attention to corresponding coding as well as correct
locking (see picture above).

Replacing the battery
When the charge is too low or the battery is empty, the data stored in the CMOS RAM
(e.g. date and time) might not be accurate.
Then the lithium battery must be replaced.
Caution
Notice:
Incorrect replacement may lead to risk of explosion.
The battery may be replaced only with an identical battery or with a type
recommended by the manufacturer.
Ensure that you insert the battery in the right way (see polarity).
Note:
Do not throw lithium batteries into the household waste. They must be disposed of
in accordance with local regulations concerning special waste.

2.4 Watchdog
In the BIOS set-up the following setting options are intended for the watchdog.
Address:
Three I/O addresses are offered for selection
over which the application software can access to the watchdog.
Timeout:
Can be set from 400 milliseconds until 600 seconds.
Within the set time, the watchdog must be triggered by the application,
otherwise a RESET is caused.
Delay:
Can be set from 1 until 1800 seconds.
The set time is bided after the start of the watchdog for one time,
until the timeout counter begins to count.
The application software can access to the watchdog register via the set I/O address
with IN and OUT commands.
ISA bus Designation Description
Bit 0 RUN (R/W) 1 = Timeout counter counting.
Change 0 on 1 resets TIMEOUT (Bit2) and initializes all counters.
Bit 1 TRIGGER (R/W) must be toggled within the set time period
in order to reset the timeout counter.
Bit 2 TIMEOUT (R) 0 = no timeout. Default after Power-Up or after setting Bit0.
1 = Timeout is occurred. Reset was caused.
With timeout the watchdog is stopped.
Furthermore the watchdog can be addressed via the I2C bus.
In this case timeout and delay counters can be loaded by the application software.
Starting and triggering of the watchdog is only possible by the manner as described above.
Watchdog I2C interface: Device address = B0h/B1h
The watchdog consists of individual byte registers.
Write: Device address B0h, register address, data byte
Read : not possible
For writing the watchdog must not have been started (Bit 0 via I/O = 0)
Address Data Byte Reset Condition
Read/Write
Bit Remark
0TimeOut Low Byte 100d WByte
1TimeOut High Byte 0WByte
2Delay Low Byte 100d WByte
3Delay High Byte 0WByte
Settings in the VIA Southbridge 82C686: Device 7 Function 0: Rx76[1] = 1 Rx8B[0] = 1
Rx[79] and Rx[78] contains the I/O addresses
e.g.: Rx[79] = 03
Rx[78] = 00 corresponds to address 300H
