you should check if the connector on the floppy drive has an extra
slot. If the slot is up, pin number one should be on the right. Please
refer to any documentation that came with the drive for more
information.
If needed, connect the B: drive to the connectors in the middle of
the cable as described as above.
If your cable needs to be custom made, you can find the pin
assignments for the board's connector in Appendix A.
2.10 Parallel port connector (CN3)
Normally, the parallel port is used to connect the card to a printer.
The PCM-5825 includes a multi-mode (ECP/EPP/SPP) parallel port,
accessed through CN3 - a 26-pin flat-cable connector.
You will need an adapter cable if you use a traditional DB-25
connector. The adpater cable should have a 26-pin connector on
one end and a 25-DB connector on the other.
The parallel port is designated as LPT1 and can be disabled or
changed to LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated as IRQ7.
The proper ECP/EPP DMA channel can be selected via the BIOS
setup.
2.11 Keyboard and PS/2 mouse connector
(CN21)
The PCM-5825 board provides a mini-DIN keyboard connector,
which supports both a keyboard and a PS/2 style mouse. In most
cases, especially in embedded applications, a keyboard is not used.
If the keyboard is not present, the standard PC/AT BIOS will
report an error or failure during the power-on self test (POST)
after resetting the PC. The PCM-5825 board's BIOS standard setup
menu allows you to select "All, But Keyboard" under the "Halt
On" selection. This allows non-keyboard operation in embedded
system applications without the system halting during the POST.
