Flash Eeprom; Hardware Cmos & Password Reset; Dram Installation - TYAN THUNDER 2 ATX Manual

Flash EEPROM

The S1696DLUA uses flash memory to store BIOS programs. It can
be updated as new versions of the BIOS become available. You can
upgrade your BIOS easily using the flash utility (see page 58).
JP4 determines which type of EPROM is used. This jumper has been
set to match the onboard BIOS chip. The factory default for the
S1696DLUA is on pins 1-2. Depending on the type of EPROM used,
some boards will have JP4 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 JP3 to pins 2 and 3 (see previous page for
location of JP3).
3. Wait for 2 seconds, then return jumper JP3 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 S1696DLUA uses a 64-bit data path from memory to CPU and
can accommodate up to 1024MB of EDO RAM and 512MB of
SDRAM. SDRAMs (Synchronous DRAMs) are 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 unbuffered (see figure on the next page). All installed
memory will be automatically detected, so there is no need to set
jumpers. The 440LX AGPset can cache up to 512MB of RAM.
