Most modern BIOS's allow automatic detection of hard disk drive parameters. These are some of the primary CMOS settings that apply to hard drives (and CD/DVD-ROM drives, etc.). This setting can be individually configured for the primary master and primary slave device and the secondary master and secondary slave device.
S.M.A.R.T. for Hard Disks
Some BIOS's have a specific BIOS setting to enable monitoring of hard disks that support the SMART (Self-Monitoring And Reporting Technology) feature, which can allow the hard disk to report impending failures of the hard disk, under some circumstances. The default for this setting is “Disabled”.
- Type
This setting determines the "type" of the IDE device. Auto: This setting activates dynamic IDE auto detection for the device. The device will be auto detected by the BIOS each time the system boots.
CD-ROM: To tell the BIOS that you are using a CD-ROM in that IDE device position.
Disabled/None: Use this option to tell the BIOS that there is no drive at all in this IDE device position.
