Chapter 4 BIOS Setup Utility

•ATA (PI) 80 Pin Cable Detection – [Host & Device], [Host], or [Device] This field selects the method used to detect the ATA (PI) 80-pin cable.

∗If [Host & Device] is selected, the BIOS uses both the onboard IDE controller and the IDE hard disk drive (HDD) to detect the type of IDE cable used.

∗If [Host] is selected, the BIOS uses only the onboard IDE controller to detect the type of IDE cable used.

∗If [Device] is selected, the BIOS uses only the IDE hard disk drive (HDD) to detect the type of IDE cable used.

NOTE	An 80-conductor ATA cable is required when operating with Ultra
	ATA/66, Ultra ATA/100 and Ultra ATA/133 IDE hard disk drives. The
	standard 40-conductor ATA cable cannot handle the higher speeds. Due to
	the plug compatibility of the 80-conductor ATA cable to the standard 40-
	conductor ATA cable, the BIOS must have a feature to set this or
	determine if the 80-conductor ATA cable is present. The BIOS does this
	by searching for a break (open) in one of the lines in the 80-conductor
	ATA cable that is normally connected in the standard 40-conductor ATA
	cable. If a faster speed is set in the BIOS than the connected cable can
	support, the BIOS instructs the IDE HDD to run at the correct (or slower)
	speed for the cable type detected.

>USB Configuration

Depending on the USB devices detected, examples similar to those listed below may be displayed.

Module Version - x.xx.xx-xx.x	Or	Module Version - x.xx.xx-xx.x
USB Devices Enabled:		USB Devices Enabled:
2 Drives		None:

•USB Function – [Disabled], [2 USB ports], [4 USB ports], or [6 USB ports]

•USB 2.0 Controller – [Disabled] or [Enabled]

•Legacy USB Support – [Disabled], [Enabled], or [Auto]

This field supports the USB mouse and USB keyboard when no USB drivers are loaded for the operating system (OS). If this option is not enabled, the attached USB mouse and USB keyboard will not be available until a USB compatible OS is fully booted with all the USB drivers loaded.

CAUTION If this field is not set to [Enabled] or [Auto] the USB mouse and USB keyboard will not be recognized by the BIOS until the OS is fully booted and the USB drivers are loaded.

∗If [Enabled] is selected, USB devices may be used during boot time and while using DOS.

∗If [Auto] is selected, USB devices, such as a USB keyboard or USB mouse will be automatically detected and if found, will be initialized and utilized during Boot time.

•USB Keyboard Legacy Support – [Disabled] or [Enabled]

•USB Mouse Legacy Support – [Disabled] or [Enabled]

•USB Storage Device Support – [Disabled] or [Enabled]

•Port 64/60 Emulation – [Disabled] or [Enabled]

∗If this field is set to [Enabled], it allows the BIOS to provide full PS/2 based legacy support for USB keyboard and mouse. It provides the PS/2 functionality such as keyboard lock, password setting, scan code selection etc. to USB keyboards.
