CONNECTORS
The ZT 8907 includes several connectors to interface to application-specific devices.
Refer to the "
" section in Appendix B for complete connector descriptions
and connector pinouts, as well as cabling information.
JUMPER DESCRIPTIONS
The ZT 8907 includes several jumper and cuttable trace configuration options for
features that cannot be provided through the BIOS SETUP utility (discussed in the
"
" section below). Refer to Appendix A, "
," for details.
REMOVING THE zPM MEZZANINE CARD
Ziatech zPM mezzanine cards plug into the 150-pin PCI mezzanine connector provided
on many Ziatech CPUs (J13 on the ZT 8908). Mechanical connection of the boards is
reinforced by metal or nylon standoffs that are screwed through mounting holes in each
board.
Important:
If it is necessary to disconnect a zPM mezzanine card, Ziatech recommends
removing only the screws attaching the card to the standoffs. If it is necessary to
remove the standoffs from the CPU, be aware that on some CPUs washers may be
located between the PCB and the standoffs. Be sure to retain and reinstall these
washers to their original position if they are removed for any reason.
Also take care when installing and removing the zPM mezzanine card to prevent
premature wear or accidental bending of the 150-pin (and on some mezzanine cards,
an additional 16-pin) connector. When removing the card, disengage the pins evenly
across the length of the connectors instead of prying only from one side. It may be
helpful to gently wiggle the card from side to side when removing it.
Warning:
To avoid damage to the CPU and the mezzanine card,
install and remove the mezzanine card at a static-free workstation.
SETUP
The ZT 8907 has many features that can be configured with the BIOS SETUP utility.
The SETUP utility is executed during the boot sequence when the
"s"
key is typed. In
DOS systems, SETUP may be executed by running the SETUP.COM program from the
command line.
The BIOS SETUP utility on all Ziatech CPUs allows configuration of options such as
base memory and extended memory size selection, boot source, hard disk type, and
floppy disk type. On the ZT 8907, the BIOS SETUP also allows routing of interrupts,
memory mapping, and I/O mapping for the STD 32 bus.
