Connecting the Floppy Disk Cable
1. Install the 34-pin header connector
into the shrouded floppy disk
header (J4) on the system board.
The colored edge of the ribbon
should be aligned with pin 1 of J4.
2. Install the other 34-pin header
connector(s) into the disk drive(s).
Align the colored edge of the daisy
chained ribbon cable with pin 1 of
the drive edge connector(s). The
end-most connector should be
attached to the drive you want to
designate as Drive A.
2.2.5.4 Floppy Disk Drive Controller
The system board is equipped with a shrouded floppy disk header
that supports two standard floppy disk drives. To prevent
improper floppy cable installation, the shrouded floppy disk header
has a keying mechanism. The 34-pin connector on the floppy cable
can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header.
