Onboard IDE-1 Controller
Common Options : Enabled, Disabled
This BIOS feature is actually a misnomer because there is only one IDE controller integrated into current chipsets.
This single IDE controller comes with two IDE channels, each of which supports up to two IDE drives. Therefore, the IDE controller supports a total of four IDE devices through two IDE channels.
When enabled, the IDE channel will be able to provide support for up to two IDE drives.
When disabled, the IDE channel will be disabled. Any attached IDE drives will not be accessible. However, this frees up an IRQ, which can be used by other devices. Disabling this IDE channel will also speed up the booting sequence a little as the BIOS will not need to query this channel for IDE devices when it boots up.
You should leave this enabled if you are using this IDE channel. Disabling it will prevent any IDE devices attached to this channel from being accessed.
If you are not attaching any IDE devices to this IDE channel (or if you are using a SCSI / an add-on IDE card), you can disable this IDE channel to free an IRQ and speed up the booting sequence.
