9)Primary (Blue) / Secondary (Black) IDE Connectors (40-1 pin PRIMARY IDE and SECONDARY IDE)

(40-1 pin PRIMARY ATA100 and SECONDARY ATA100)

These connectors support the IDE hard disk ribbon cables supplied with the motherboard. Connect the cable’s blue connector to the motherboard’s primary IDE connector (recommended) or the secondary IDE connector. Then connect the opposite end of the cable to your UltraDMA/100/66 device (hard disk drive). A second slave hard disk may be attached to the intermediate connector on the cable. If a second hard disk drive is connected, you may reset its jumper to Slave mode. Refer to your hard disk documentation for the jumper settings. It is recommended that non-UltraDMA/100/66 devices be connected to the secondary IDE connector. BIOS now supports specific device bootup (see 4.4.1 Advanced CMOS Setup). (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged). If you have more than two UltraDMA100/66 devices, you will need to purchase another UltraDMA100/66 cable.

The A7V133 motherboard is supplied with two extra onboard IDE connec- tors: one Primary ATA-100 IDE and one Secondary ATA-100 IDE. You can use them to setup the RAID 0 or 1 arrays and to support extra IDE devices. For the purposes of RAID arrays, adjust the jumper settings: see 3.4 Motherboard Setting, ATA-100/RAID 0 or 1, page 20. A total of eight hard-disks, two on each IDE connector, can be connected to the A7V133

TIP: For high-performance and RAID 0 or 1 set ups, you should always setup two hard disks with two separate ribbon cables, one for the primary IDE con- nector and another for the secondary IDE connector. Usually, both disks may be set to the Master settings: see 5.4 Software Setup for more information about RAID. Also, you may install one operating system on an IDE drive and another on a SCSI drive and select the boot disk through 4.4.1 Advanced CMOS Setup.

NOTE: UltraDMA/100 is backward compatible with DMA/66 and DMA/33 and with all with existing DMA devices and systems, so there is no need to upgrade current EIDE/IDE drives and host systems.

IMPORTANT: UltraDMA66 and UltraDMA100 IDE devices require a 40-pin 80-conductor cable and RAID arrays only operate with such cables.
