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 Performance Rich IDE circuitry on hard disk drive C: (disk 0). The
settings are Auto, Mode 0, Mode 1, or Mode 2. If Auto is selected, AMIBIOS 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 Performance Rich IDE circuitry on hard disk drive D: (disk 1). The
settings are Auto, Mode 0, Mode 1, or Mode 2. If Auto is selected, AMIBIOS 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.
