Board Installation
Like the IDE and floppy cables, the colored or red edge of the cable always
denotes pin 1 (Figure 7 previous page). Similarly, pin 1 on the motherboard is
always pointing towards the keyboard connector or edge of the board. TYAN
cables conform to the IBM standard pinouts and will differ from most other
manufacturers'. Other cables will not work on TYAN boards.
The Printer and Com1 ports are on the same back plate. You want to make sure
that you correctly align the connectors with the pins on the board beacuse
they are easy to miss. On most TYAN cables, there should be a pin missing on
the motherboard. This is normal since it lines up with a key pin on the I/O
connectors. This forces you to align the connector in the correct direction.
The Printer port and Com2 are easily confused. The Printer cable is always
attached with Com1 (Figure 8) where Com2 is supplied seperately on a second
back plate (Figure 9). Remember: Only TYAN cables will work on this
motherboard. If you are using an existing case with old cables, your system
may not function properly. Use TYAN-approved connectors to ensure
compatibility.
Connecting the PS/2 mouse.
This board has a PS/2 mouse port built in. Simply plug your PS/2 mouse into
the PS/2 port; the pins will allow you to plug the mouse in only in the correct
way. If you have any trouble locating the port, turn to the full page
motherboard map on page 25. Warning: When plugging in your keyboard
and mouse, or when plugging anything into a serial or Com port, make sure
that the power is off. Connecting these devices and ports while the power is
important!
on iscalled "hot plugging," and may damage your system.
