|
|
.Sh DESCRIPTION
|
|
This driver provides access to floppy disk drives and QIC40/80 tapedrives.
|
|
In /dev for each floppy device a number of minor devices are present. The
|
|
/dev/fd* devices with trailing alphabetic characters are used to indicate
|
|
'partitions' on the floppy disk. The /dev/fd*.<number> are devices that
|
|
indicate the size of the floppy disk (so: 720kB, 1440kB etc). The latter
|
|
are used for formatting disks using fdformat or for accessing different
|
|
density disks in multidensity drive. Example: 720kB disk in a 1.44Mb drive.
|
|
.Pp
|
|
Normally, the driver will ask the system's CMOS memory to obtain the
|
|
floppy drive configuration. Some machines do not store any form of a
|
|
configuration value in their CMOS. Use the flags value
|
|
.Ql 0x1
|
|
to pretend a 1.44 MB floppy drive as the first unit, without asking the
|
|
CMOS for it.
