two or four HDDs to get RAID functions, it is very convenient for you to install the HDDs to IDE3, IDE4, IDE5 or IDE6. See the Chapter 4 for detailed information about RAID settings. (For AT7 Full Version Only)

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 HDD 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”.

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.

Note

!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 & Ultra DMA 133 devices on IDE1 to IDE6, 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.

!HPT 374 IDE controller is designed to support high-speed and high performance mass storage devices. Thus, we suggest that you don’t connect non-disk devices that use ATA/ATAPI interfaces, such as a CD-ROM, to HPT 374 IDE connector (IDE3 ~ IDE6). (AT7 Full Version Only)
