|Check the jumper setting on your optical drive and set it appropriately. Settings are Master, Slave and Cable Select (CS). This jumper should be set to the way you intend to use this device and your BIOS setting will need to match this setting.|
Check your BIOS settings for the following:
OnBoard IDE Controller - should be set to enabled
IDE Device Configuration - The setting will depend on the jumpering of your optical drive as follows:
If the optical drive is jumpered as a master then set the type in the IDE Master section to CD/DVD. This may initially default to auto which is usually the setting for hard drives.
If the optical drive is jumpered as a slave then set the type in the IDE Slave section to CD/DVD. This may initially default to auto which is usually the setting for hard drives.
If the optical drive is jumpered as a Cable Select (CS) then set the type in the IDE Master or IDE Slave section to CD/DVD depending on which of the two IDE connectors you are using. However as you are using a 40 conductor IDE cable, CS options have to be qualified. Read on for the explanation.
Cable Select is not the easiest to work with as it is subject to the vagaries of which type of IDE cable you are using. It is more straight forward for 80 conductor than for a 40 conductor cable. Read more here on that:
I suggest that it would be easiest for you if you either set the jumper to Master OR Slave and then set the BIOS setting appropriately.
You may however have to reconsider this configuration at a later date if you decide to attach another IDE device to the unused cable position.
☺ When everything else fails, read the instructions.
