Installing the Motherboard
(12). IDE1, IDE2, IDE3 and IDE4 Connectors
allows for four additional IDE devices in your computer system. Especially, if you want to connect two or
four HDDs to get RAID functions, it is very convenient for you to install the HDDs to IDE3 and IDE4.
See the Chapter 4 for detailed information about RAID settings.
If you want to connect two hard drives together through one IDE channel, you must configure the second
drive to Slave mode after the first Master drive. Please refer to the drives' documentation for jumper
settings. The first drive connected to IDE1 is usually referred to as "Primary Master", and the second
drive as "Primary Slave". The first drive connected to IDE2 is referred to as "Secondary Master" and the
second drive as "Secondary Slave".

! The Master or Slave status of the hard disk drive is set on the hard disk itself. Please refer to the
hard disk drive user's manual.
! To connect Ultra DMA 100 devices on IDE1, IDE2, IDE3 or IDE4, an Ultra DMA 66 cable is
required.
! A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to
the IDE connector pin 1, before inserting the wire connector into the IDE connector.
This motherboard provides two IDE ports (IDE1 &
IDE2) to connect up to four IDE devices in Ultra
DMA 100 mode by Ultra DMA 66 ribbon cables.
Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections
with the motherboard. Connect the single end (blue
connector) at the longer length of ribbon cable to the
IDE port on motherboard, and the other two ends
(gray and black connector) at the shorter length of the
ribbon cable to the connectors on hard drives.
KG7-RAID's built-in HighPoint HPT 370A chipset
gives you the capability to support Ultra DMA 100.
It provides two IDE channels (IDE3 & IDE4) that
also support Ultra DMA 100 specifications, and it
Note
Keep away from connecting
one legacy slow speed device,
like CD-ROM, together with
another hard drive on the same
IDE channel; this will decrease
your integral system
performance.
