Ide1 And Ide2 - VIA Technologies K7MKLE User Manual

2-12 IDE 1 and IDE 2
The IDE connectors are used to connect IDE devices such as Harddisks and CD-ROM
drives to the motherboard. Each connector constitutes an IDE channel, each channel
accepts 2 IDE devices, one Master and one Slave. The IDE 1 connector is also known as
the primary channel, IDE 2 is the secondary channel. Therefore the primary Master is the
IDE device connected to IDE 1 as Master, the primary Slave is the IDE device connected to
IDE 1 as Slave. Jumpers on the IDE device determine Master and Slave settings. Your
harddisk or CD-ROM should have a sticker with jumper settings. Make sure that you set
these jumpers correct. Please use the following advise as reference:
If you have only device connected to an IDE connector, always set it as Master.
If you have one HDD and CD-ROM in your system, then connect the HDD to IDE 1
as Master, and the CD-ROM to IDE 2 as Master.
If you have one Harddisk and one CD-ROM connected to the same IDE connector,
set the HDD to Master and the CD-ROM to Slave.
Ultra DMA
This motherboard supports Ultra DMA 66 IDE devices, if your southbridge is the 82C686B
it will even support Ultra DMA 100. If the UDMA mode for the IDE channels are set to
auto in the BIOS the motherboard will use the fastets possible interface to comminucate
with your IDE devices. (Note however that windows may not support UDMA 100 yet, see
the FAQ chapter)
