can connect up to four hard disk drives, CD-ROM, or other devices.

The first hard drive should always be connected to IDE1. IDE1 can connect a Master

IDE2 can also connect a Master and a Slave drive.

MSI Reminds You...
If you install two hard disks on cable, you must configure the second
drive to Slave mode by setting its jumper. Refer to the hard disk
documentation supplied by hard disk vendors for jumper setting
instructions.
Chassis Intrusion Switch Connector: JCI1
This connector is connected to a 2-pin chassis switch. If the chas-
sis is opened, the switch will be short. The system will record this
status and show a warning message on the screen. To clear the
warning, you must enter the BIOS utility and clear the record.
