Page 17: Installing Memory
Please keep in mind that although some memory modules may appear to be high-quality, they may con- tain inferior or substandard parts. The type of memory you choose to install should be checked against the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com Here are some details of memory installation for this board: At least one non-registered, unbuffered DIMM must be installed in order to POST. -
Page 18: Removing A Dimm
The notch position in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see Figure 2.1 below). All installed memory will be auto-detected, so there is no need to set any jumpers. Figure 2.1 unbuffered buffered http://www.tyan.com... -

Information stored in a buffer is temporarily stored, not perma- nently saved. Bus: a data pathway. The term is used especially to refer to the connection between the processor and system memory, and between the processor and PCI or ISA local buses. Tomcat i815T S2080... - Page 50 As with IRQs, it is vital that you do not double up devices on a single line. Plug- n-Play devices will take care of this for you. Doze mode: in this mode, only the CPU’s speed is slowed. http://www.tyan.com...
- Page 51 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 52 Pipeline burst SRAM: a fast secondary cache. It is used as a secondary cache because SRAM is slower than SDRAM, but usually larger. Data is cached first to the faster primary cache, and then, when the pri- mary cache is full, to the slower secondary cache. http://www.tyan.com...
- Page 53 Serial port: called as such because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another). Tomcat i815T S2080...
- Page 54 ZIF socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without damag- ing the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and the metal level is pulled down. This shifts the processor over and down, guiding it into place on the board. http://www.tyan.com...

Page 55: Technical Support
You may obtain service by calling the manufacturer for a Return Merchandise Authorization (RMA) number. The RMA number should be prominently dis- played on the outside of the shipping carton and the package should be mailed prepaid. Tyan will pay to have the board shipped back to you. - Page 56 CAUTION: Lithium battery included with this board. Do not puncture, mutilate, or dispose of battery in fire. Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type rec- ommended by manufacturer. Dispose of used battery according to manufacturer instructions and in accordance with your local regulations. Document # D1456-100 http://www.tyan.com...
