Yukon HX Motherboard User Manual

Parallel Port ECP DMA
This option is only available if the setting for the Parallel Port Mode option is ECP. The
settings are “DMA CH 1” and “DMA CH 3”. 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”.
Auto-Detect Hard Disks
This “Auto-Detect Hard Disks” option detects the parameters of IDE hard disk drives,
and automatically enters them into the standard CMOS setup screen.
Change User Password & Change Supervisor Password
AMIBIOS has two optional password features. “Supervisor Password” sets a password
that will be used to protect the system and the setup utility; “User Password” sets a
password that will be used exclusively on the system. The system can be configured so
that all users must enter a password every time the system boots or when the BIOS
Setup is executed. The password is stored in CMOS RAM. When you select Supervisor
or User, AMIBIOS prompts for a password. You must set the Supervisor password
before you can set the User password. Enter a 1-6 character password. The password
does not appear on the screen when typed. Make sure you write it down. If you forget
it, you must drain CMOS RAM and reconfigure the system.
Auto Configuration with Optimal Settings
You can load the Optimal default settings. The Optimal default settings are best-case values
that should optimize system performance. If CMOS RAM is corrupted, the Optimal settings are
loaded automatically.
Auto Configuration with Fail Safe Settings
You can load the Fail-Safe Setting by pressing <enter> at the Fail-Safe Setting. The
Fail-Safe settings provide far from optimal system performance, but are the most stable
settings. Use this option as a diagnostic aid if the system is behaving erratically.
