Yukon HX Motherboard User Manual Memory The Yukon HX motherboard supports base (conventional) and extended memory. Operating systems such as MS-DOS†, OS/2†, UNIX†, and all application programs use base memory. For better performance, OS/2 and UNIX as well as many MS-DOS applications use extended memory. The motherboard supports up to 128 MB of DRAM memory. DRAM is implemented through 72-pin single in-line memory modules (SIMMs). The motherboard contains four SIMM sockets.
1 Product Description 48mA direct output driver Enhanced digital data separator A and B drive may be swapped supports two 360K, 720K, 1.2M, 1.44M, 2.88M floppy disk drives • Multi-mode high performance parallel port Standard mode -- bi-directional SPP Enhanced mode -- EPP 1.7 and EPP 1.
Yukon HX Motherboard User Manual ISA Plug and Play Capability This provides auto-configuration of Plug and Play ISA cards and resource management for legacy (non Plug and Play) ISA cards. BIOS Upgrades Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS without having to disassemble the system. The flash upgrade process can be done by running a utility from a diskette or hard disk, or over a network.
1 Product Description Keyboard/Mouse Controller The I/O controller stores the keyboard and mouse controller code. Real-Time Clock and CMOS RAM Yukon HX motherboard uses Dallas real time clock for CMOS storage. The time for the clock and the CMOS values can be set by using the system BIOS Setup program, described in Chapter 2. Fan Connector The board contains a connector for a CPU fan. Speaker The board has a connector for an offboard speaker.
Using the BIOS Setup Program 2 This chapter tells how to use the Setup program that is built into the BIOS. The Setup program makes it possible to change configuration information (such as the types of peripherals that are installed) and the boot-up sequence for the system. The Setup information is stored in CMOS random access memory (RAM) and is backed up by a battery when power is off. If the board does not operate as described here, see Chapter 4 for problem descriptions and error messages.

Yukon HX Motherboard User Manual Standard CMOS Setup This section describes the Setup options found on the Standard CMOS Setup menu. If you select certain options from the main screen (e.g., Primary IDE Master), the Setup program switches to a subscreen for the selected option. Date / Time Select the Date/Time option to change the date or time. The current date and time are displayed. Enter new values through the displayed window.
2 Using the Setup Program Advanced CMOS Setup This section describes the Setup options available in the Advanced CMOS Setup menu. If you select certain options from the Advanced CMOS screen, the Setup program switches to a subscreen for the selected option. Quick Boot Set this option to “Enabled” to instruct the AMIBIOS to boot quickly when the computer is powered on. It does not test system memory above 1MB. The Optimal and the FailSafe default settings are “Disabled”.
Yukon HX Motherboard User Manual appears every time the computer is turned on. If “Setup” is chosen, the password prompt appears when BIOS Setup is executed. The default settings for Optimal and Power-On are “Setup”. Parity Check Set this option to “Enabled” to check the parity of all system memory. The settings are “Disabled” or “Enabled”. The default settings for Optimal and Fail-Safe are “Disabled”.
2 Using the Setup Program Advanced Chipset Setup When selected, it brings up the Advanced Chipset Setup subscreen. Memory Hole Use this option to specify an area in memory that cannot be addressed on the ISA bus. The settings are “Disabled”, “512-640K”, are “15-16MB”. The default setting is “Disabled”. DRAM Timings Choose DRAM timings from “70ns”, “60ns”, or “Manual”. When choosing “60ns”, the system performance will be the best if you use the 60ns DRAM.
Yukon HX Motherboard User Manual Power Management Setup Power Management Setup options are described in the following section. Power Management / APM Set this option to “Enabled” to enable the power management and APM (Advanced Power Management) features. The default setting is “Disabled”. Green PC Monitor Power State This option specifies the power management state that the Green PC-compliant video monitor enters after the specified period of display inactivity has expired.
2 Using the Setup Program Slow Clock Ratio The settings are expressed as a ratio between the normal clock speed and the power down clock speed. This option specifies the speed at which the system clock runs in power saving mode. The settings are 1:1, 1:2 (half as fast as normal), 1:4 (the normal clock speed), 1:8, 1:16, 1:32, 1:64, and 1:128. The default setting is 1:8. IRQ3 - IRQ15 The settings of this option are “Ignore”, “Monitor”, “Wakeup”, and “Both”.
Yukon HX Motherboard User Manual PCI IDE BusMaster Set this option to “Enabled” to specify that the IDE controller on the PCI local bus has bus mastering capability.

The default setting is “DMA CH 3”. OnBoard IDE This option specifies the onboard IDE controller channels that will be used. The settings are “Primary”, “Secondary”, “Both”, and “Disabled”. The default setting is “Both”.
2 Using the Setup Program Save Settings and Exit Saves the changes to CMOS RAM and exits the Setup program. You can also press the key anywhere in the BIOS Setup program (main menu) to do this. Exit Without Saving Exits the Setup program without saving any changes. This means that any changes made while in the Setup program are discarded and NOT SAVED. Pressing the key in BIOS Setup program (main menu) will do this.
Installing and Configuring Jumpers & Optional Components 3 This chapter describes the following: • Jumper block locations and functions. • Procedures to remove and install optional components. • Information about replacing the battery. Before You Begin • Be sure to do each procedure in the correct order. • Set up an equipment log to record the system model and serial numbers, all installed options, and other information about the system.
3 Installing and Configuring Motherboard Options Add-in boards can be extremely sensitive to ESD and always require careful handling. After removing the board from its protective wrapper or from the system, place the board flat on a grounded, static-free surface, component-side up. Use a conductive foam pad if available, but not the board wrapper. Do not slide the board over any surface.
