PCI IDE Prefetch Mode
Enabling this option enables this performance enhancement feature on the onboard PCI IDE. IDE data
prefetch, when enabled, saves valuable CPU time by taking the data from the IDE drive ahead of the CPU
request. The settings are Enabled or Disabled. The Optimal and Fail-Safe default settings are Enabled.
PCI IDE 0 Transfer Mode
This option sets the data transfer mode for the PCI IDE circuitry on hard disk drive C: (disk 0). The settings
are Auto, Mode 0, Mode 1, or Mode 2. If Auto is selected, WinBIOS automatically determines the optimal
mode. The WinBIOS Auto Detect Hard Disk feature can detect and report all IDE drive parameters. The
Optimal and Fail-Safe default settings are Mode 0.
PCI IDE 1 Transfer Mode
This option sets the data transfer mode for the PCI IDE circuitry on hard disk drive D: (disk 1). The settings
are Auto, Mode 0, Mode 1, or Mode 2. If Auto is selected, WinBIOS automatically determines the optimal
mode. The WinBIOS Auto Detect Hard Disk feature can detect and report all IDE drive parameters. The
Optimal and Fail-Safe default settings are Mode 0.
Secondary IDE Drive
Set this option to Enabled when using the secondary IDE controller to control the third and fourth IDE
drives installed in the computer. The settings are Enabled or Disabled.
