Board Installation
The colored stripe on the cable indicating pin 1 should face towards the rear of
the case (towards the ATX connectors), as with the IDE cables. Please refer to
your documentation for proper installation, or see Figure 5 on page 14.
Some symptoms of incorrectly installed floppies are:
•
Floppy drives are not detected: usually caused by faulty cables,
backward cables, or a bad floppy or motherboard. Try another single floppy
drive to verify the problem or try another cable. Also, check to see if the
onboard floppy is enabled in the BIOS.
•
Floppy Drive Fail message at bootup: the cable, floppy, or motherboard
may be faulty. Try another cable or floppy drive to verify.
•
Light on the floppy is on constantly: a dead give-away that the cable is on
backwards. Reverse the cable at the motherboard end and try again.
Next are the Com and Printer ports.
Like the IDE and floppy cables, the colored or red edge of the cable always
denotes pin 1 (Figure 7). 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
