Onboard Floppy Disk Controller This parameter lets you enable or disable the onboard floppy disk controller. The default setting is Enabled. Onboard IDE Primary Channel This parameter lets you enable or disable the primary IDE channel. When enabled, it allows you access the devices connected to the primary channel. When disabled, it deactivates the connected devices. The default setting is Enabled. Chapter 3 - BIOS Utility 3-27 Onboard IDE Secondary Channel This parameter lets you enable or disable the secondary IDE channel. When enabled, it allows you access the devices connected to the secondary channel. When disabled, it deactivates the connected devices. The default setting is Disabled. Onboard PS/2 Mouse (IRQ 12) This parameter enables or disables the onboard PS/2 mouse. When enabled, it allows you to use the onboard PS/2 mouse assigned with IRQ12.

PCI Device Latency Timer This parameter allows you to set the length of time for a PCI device to use the PCI bus. A PCI master can burst indefinitely as long as the target can source/sink the data, and no other agent requests for the bus. If another PCI device requests for the use of the PCI bus, a PCI bus arbitration takes place, and the tenure of the device currently using the PCI bus cannot go over the PCI latency time set in BIOS. This setting depends on your application. For example, if you install a high bandwidth block I/O card, e. g. , FDDI, the longer the latency time the better. This setting only affects the primary PCI components (PCI slots 1, 2, 3, 4, and onboard LAN). The secondary PCI components (PCI slots 4) are always set to 20 PCI clocks. The default setting is 20. PCI IRQ Sharing Setting this parameter to Yes allows you to assign the same IRQ to two different devices. [. . . ] Be sure that the SCSI bus is properly terminated.
