17. OPTIONAL IDE INTERFACE
The ZT 8907 supports a local Intelligent Drive Electronics (IDE) hard disk interface (J15)
attached to the solder side of the board. This feature is useful for single board
applications as well as for STAR SYSTEMs where the ZT 8907 needs to have a local
(non-shared) hard disk.
Because the hard disk drive market continually improves capacity, the specific size of
the drive (in megabytes) sold with this option may change. In general, Ziatech offers a
higher capacity drive for the same or similar price when a new drive is qualified.
The onboard IDE interface is a factory load option at Ziatech. Option D1 to the ZT 8907
includes a hard disk, cable, and connector. When configured for local IDE operation, the
ZT 8907 requires one additional slot in the STD 32 card cage.
HARD DISK MOUNTING
The IDE hard disk is mounted to the solder-side of ZT 8907 on short standoffs. A cable
(ZT 90201) interfaces to connector J15 on the ZT 8907 to provide power and IDE
signals to the drive. The integrated drive is a 2.5 inch family drive, using a 2 mm
connector interface. Local 3.5 inch IDE drives are not supported by the ZT 8907.
SELECTING IDE OPERATION TYPE
Enable the ZT 8907 for either onboard IDE or STD 32 IDE operation through the BIOS
SETUP utility. Access the SETUP utility by pressing the "
S
" key while the system is
booting.
