User manual TYAN TITAN TURBO AT-2

[. . . ] Technical Support Should a problem arise with your system, you should first turn to your reseller. Your system has most likely been configured by them, and so they should have the best idea of what is in your system. Further, if you purchased your system from a dealer nearby, you can actually bring your system to them to have it serviced instead of fiddling with it yourself. If your reseller is unable to assist you, try our web page, http:// www. tyan. com, or our newsgroup, alt. comp. periphs. mainboard. tyan. Returning Merchandise for Service During the warranty period, contact your distributor or system vendor first for any product problems. [. . . ] Disabled BIOS will not search for the type of floppy disk drive by track number. Note that there will not be any warning messages if the drive installed is 360KB. w Boot Up NumLock Status Determines whether or not NumLock is active when the system boots. On Off Number keys are active on keypad. Arrow keys are active on keypad. w Boot Up System Speed Select High to boot at the default CPU speed; select Low to boot at the speed of the AT bus. If you are using old software­or certain add-in peripherals­you may need to use the slower CPU speed. wTypematic Rate Setting, Typematic Rate (char/sec), and Typematic Delay. The Typematic Rate Setting option enables or disables the Typematic Rate and Typematic Rate Delay options. TheTypematic Rate (6, 8, 10, 12, 15, 20, 24, or 30 characters per second) and Typematic Rate Delay (250, 500, 750, or 1000 milliseconds) control the speed at which a keystroke is repeated. Typematic Rate Delay controls the gap between key compression and the appearance of the character on-screen. The character is then printed repeatedly at the speed set by the Typematic Rate. S1571 D1181-001 http://www. tyan. com 29 BIOS Configuration w Security Option This option allows you to select whether a password (if you have one) is required each time the system boots, or only when you enter Setup. System The system will not boot and access to Setup will be denied if the correct password is not entered at the prompt. Setup The system will boot, but access to Setup will be denied if the correct password is not entered at the prompt. w PS/2 Mouse Enables or disables the PS/2 mouse resources. w Shadow This function allows BIOS to "shadow" firmware, that is, copy it from ROM into the system RAM. Once there, it can be read through the 16bit or 32-bit DRAM bus by the CPU. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but reduces the amount of high memory (see page 26) available for loading device drivers. Do not enable shadowing into all of the memory at once; enable each section independently. 4. 7 Chipset Features Setup ROM ISA BIOS CHIPSET SETUP UTILITY AWARD SOFTWARE, INC.

S1571 D1181-001 http://www. tyan. com 30 BIOS Configuration s Auto Configuration This function selects the optimal values for your chipset parameters. If Disabled, the chipset parameters will revert to setup information stored in CMOS. When Auto Configuration is Enabled, many of the options below will not be available. s DRAM Timing The value in this field is determined by the performance parameters of the installed DRAM chips. Unless you install new memory that has a different performance rating than the factory DRAMs, you should not alter this field. s DRAM Leadoff Timing Select the combination of CPU clocks the DRAM on your board requires before each read from or write to the memory. Beware: changing the value from the setting determined by the board designer for the installed DRAM may cause memory errors. s DRAM Read Burst Sets the timing for reads from EDO (Extended Data Output) or FP[M] (Fast Page Mode) memory.
