1.6.3 Hard Disk Connectors: IDE1/IDE2
The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
Mode 0~4, Bus Master, and Ultra DMA / 33, Ultra DMA / 66, Ultra DMA / 100
functionality.
It has two HDD connectors IDE1 (primary) and IDE2 (secondary).
You can connect up to four hard disk drives, a CD-ROM, a 120MB Floppy
(reserved for future BIOS) and other devices to IDE1 and IDE2.
These
connectors support the IDE hard disk cable provided.
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 the second hard drive on IDE1 to
Slave mode by setting the jumper accordingly.
IDE2 (Secondary IDE Connector)
The IDE2 controller can also support a Master and a Slave drive. Its configuration
is similar to IDE1. The second drive on this controller must be set to slave mode.
