HARDWARE INSTALLATION
2.7 Primary/Secondary IDE Connectors (Two 40-pin IDE)
The standard configuration of the TS-ABD4 motherboard supports two 40-pin IDE connectors
marked as IDE1 (primary channel) and IDE2 (secondary channel). Each channel supports two
IDE devices for a total of four devices. However, the TS-ABD4/R and TS-ABD4/NR is the TS-
ABD4 configured with the optional IDE RAID controller and an additional two IDE connectors
(IDE3/primary and IDE4/secondary). These two channels support up to four more IDE devices,
if the RAID function is not selected. See Sections 2.5 for details on using the IDE RAID
function. Connect the main HDD, if you are using more than one, to the “Master” connector (at
the end of the cable) and connect it to IDE1 (or IDE3 if using RAID function) (see important note
below). If your HDD supports Ultra DMA/66/100, the 80-wire cable must be use, or the HDD
won’t be able to reach this speed.
If you intend to operate two IDE devices from the same channel, one device must be set to
“Master” mode, the other to “Slave” mode. A HDD, CD ROM or other IDE device can have
either setting depending on the device’s jumper. Refer to the device’s manual for more information.

NOTE: The connectors must be attached to the IDE channels in the correct di-
rection. Make sure that the red stripe on one edge of the ribbon cable
(this may be faint and could also be a dotted line) is nearest to PIN1 (on
the left for IDE1 and IDE 2 and at the top for IDE3 and IDE4 as the
motherboard is shown in the picture below).
