system will do a cold start after the Reset button is pushed. The Reset
switch is a 2-pin connector and should be installed on pins 22 and 23 on
jumper block J8.
Flash EEPROM
The S1573S uses flash memory to store BIOS programs. It can be
updated as new versions of the BIOS become available. The flash
utility will guide you through the update process step by step (see
Chapter 5).
JP2 determines which type of EPROM is used. This jumper has been
set to match the onboard BIOS chip. The factory default for the
S1573S is on pins 1-2. Depending on the type of EPROM used, some
boards will have JP2 on pins 2-3.
Hardware CMOS & Password Reset
If you have been locked out of your system because you forgot your
password or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP1 to pins 2 and 3 (see previous page for
location of JP1).
3. Wait for 2 seconds, then return jumper JP1 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you will erase your password and reset the
CMOS to the BIOS defaults.
DRAM Installation
The S1573S uses a 64-bit data path from memory to CPU and can
accommodate up to 256MB of RAM. The mainboard supports Fast
Page Mode and EDO (Extended Data Out) 72-pin SIMMs. SDRAMs
(Synchronous DRAMs) are also supported in the DIMM slots. DIMMs
!
must be of the unbuffered variety. The position of the notch in the
DRAM Key Position will tell you whether or not a DIMM is unbuf-
