Hard Disk Connectors: IDE1 & IDE2
The mainboard has an Ultra DMA 133/100/66 controller. You can connect up
to four hard disk drives, CD-ROM and other devices.
The primary hard drive should always be connected to IDE1 as the master
drive. Both IDE drives can connect to a master and a slave drive.

If two drives are connected to a single cable, the jumper on the second drive
must be set to slave mode. Refer to the drive documentation supplied by the
vendor for the jumper settings.
