ATA100 Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100 control-
ler that provides PIO mode 0~5, Bus Master, and Ultra DMA 33/66/100 function. You
can connect up to four hard disk drives, CD-ROM, 120MB Floppy and other devices.
These connectors support the provided IDE hard disk cable.
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master
and a Slave drive. You must configure second hard drive to Slave mode by setting the
jumper accordingly.
IDE2 (Secondary IDE Connector)
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 docu-
mentation supplied by hard disk vendors for jumper setting instructions.
