[. . . ] However, it is the slowest transfer mode and should only be used when faster transfer modes cannot be used. There are two faster bidirectional modes available - the ECP (Extended Capabilities Port) and EPP (Enhanced Parallel Port) modes. ECP uses the DMA protocol to achieve data transfer rates of up to 2. 5 Mb/s and provides symmetric bidirectional communication. On the other hand, EPP uses existing parallel port signals to provide asymmetric bidirectional communication. Generally, because of its FIFOs and the DMA channel it uses, ECP is good for large data transfers (useful for scanners and printers). On the other hand, EPP is better with links that switch directions frequently (like parallel port drives). SPP / EPP / ECP Base I/O Address / Interrupt This determines the base address and interrupt of the parallel port. 378 / IRQ7 / Disabled / 278 / IRQ5 / 3BC / IRQ7 DMA Channel This BIOS feature determines which DMA channel the parallel port should use when it is in ECP mode. The ECP mode uses the DMA protocol to achieve data transfer rates of up to 2. 5 Mbits/s and provides symmetric bidirectional communications. By default, the parallel port uses DMA Channel 3 when it is in ECP mode. This feature is provided just in case one of your add-on cards requires the use of DMA Channel 3. In such a case, you can use this BIOS feature to force the parallel port to use the alternate DMA Channel 1. Please note that there is no performance advantage in choosing DMA Channel 3 over DMA Channel 1 or vice versa. As long as either Channel 3 or Channel 1 is available for your parallel port to use, the parallel port will be able to function properly in ECP mode. DMA 1 / DMA 3 Floppy Disk Controller This defines how the floppy disk controller is detected and configured.

Disabled / Enabled J22/J31/J23/J8&J17 Number of Pins Select These features are used to select 3 or 4 pin fan connector. After the setting, then you can use the function of "Auto Fan Control". 4 Pin / 3 Pin 57 http://www. tyan. com 3. 3. 5 DMI Event Logging These items are used to view and modify DMI event logs. Event Logging Select Enabled to allow logging of DMI events Disabled / Enabled ECC Event Logging Select Enabled to allow logging of ECC events Disabled / Enabled Clear all DMI event logs Setting this to `Yes' will clear the DMI event log after rebooting. No / Yes 58 http://www. tyan. com 3. 3. 6 Console Redirection Com Port Address If enabled it will use a port on the motherboard. Disabled / On-board COM A / On-board COM B / NULL Baud Rate This feature is used to enable the specified baud rate. 300 / 19. 2K / 1200 / 2400 / 9600 / 38. 4K / 57. 6K / 115. 2K Console Type This feature is used to enable the specified console type. VT100 / VT100. 8bit / PC-ANSI, 7bit / PC ANSI / VT100+ / VT-UTF8 / NULL Flow Control This feature is used to enable the flow control. [. . . ] 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. 81 http://www. tyan. com Technical Support If a problem arises with your system, you should first turn to your dealer for direct support. Your system has most likely been configured or designed by them and they should have the best idea of what hardware and software your system contains. Furthermore, if you purchased your system from a dealer near you, take the system to them directly to have it serviced instead of attempting to do so yourself (which can have expensive consequences).
