2.1 – Jumper Section Pin outs for certain connectors are available on the Tyan website: http://www.tyan.com 2.1a Front Panel Connector (J15) Your chassis will usually come with connectors to install onto the motherboard, such as HDD and Power LEDs. The Front Panel Connector (J80) has been implemented for such purposes. -

Page 36: Chapter 4: Installing The Hard Drives
If you are planning to use an UDMA-66 or 100 drive, you must use an UltraDMA-66/100 cable (Tyan has included that cable with the motherboard). Step 1: The first step is to set the hard drive to Master, Slave, or Cable Select setting, and install them according to the table below. -
Page 37: Chapter 5: System Resources
BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not occur are probably due to memory problems. If calling Tyan Tech Support, be sure that you know how many beeps your board made, and how long the beeps were. Also have other information such as your attached add-in cards, drives and OS to help speed up the support process and come to a possible solution faster. -
Page 38: Appendix: Glossary
Cache size: refers to the physical size of the cache onboard. This should not be confused with the cacheable area, which is the total amount of memory which can be scanned by the system in search of data to put into the cache. A typical setup would be a cache size of 512KB, and a http://www.tyan.com... - Page 39 EEPROM (Electrically Erasable Programmable ROM): also called Flash BIOS, is a ROM chip which can, unlike normal ROM, be updated. This allows you to keep up with changes in the BIOS programs without having to buy a new chip. Tyan’s BIOS updates can be found at http://www.tyan.com ESCD (Extended System Configuration Data): a format for storing information about Plug-n- Play devices in the system BIOS.
- Page 40 Form factor: an industry term for the size, shape, power supply type, and external connector type of the Personal Computer Board (PCB) or motherboard. The standard form factors are the AT and ATX, although Tyan also makes some Baby-AT and ATX Footprint boards. Global timer: onboard hardware timer, such as the Real-Time Clock (RTC).
- Page 41 SDRAM (Synchronous Dynamic RAM): called as such because it can keep two sets of memory addresses open simultaneously. By transferring data alternately from one set of addresses and then the other, SDRAM cuts down on the delays associated with non-synchronous RAM, which must close one address bank before opening the next. http://www.tyan.com...
- Page 42 ZIF Socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without damaging the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and a lever is pulled down. This shift the processor over and down, guiding into the board and locking it into place. http://www.tyan.com...
