/usr/pub/Solaris.drives


The PC's running Solaris in 277 Soda and 330 Soda have floppy and
CD-ROM drives available for the users.

Floppy Disks
------------

The floppy drive uses both double-density (740 KByte) and high-density
(1.44 MByte) 3.5" floppy disks; they can be purchased at most computer
and electronics stores.  The floppy drive reads both Solaris formatted
and MS-DOS formatted disks; this document is geared toward MS-DOS
users.  The drive does not read Macintosh formatted disks.

To insert a floppy disk, hold it horizontally with the label side up
and place it into the floppy disk drive.  You will hear a click and
see the eject button pop up.  Please do not force your disk into the
drive.  The drive is now ready to use.

Solaris has provided a few simple commands to read, write, and format
a floppy disk.  To format an MS-DOS floppy under Solaris, type the
following command:

	% fdformat -d /vold/dev/rdiskette0

The fdformat manual page has several other options which may be useful.

A floppy can be mounted using the programs 'volcheck' and 'eject'.  The 
following is a sample session to demonstrate the use of floppy
drive, please read the 'volcheck' and 'eject' manpages for more 
information.  This sample session uses a diskette has already been
formatted and has some MS-DOS files on it.

	% volcheck

	% cd /floppy

	% ls
	floppy0 no_name

	% cd no_name
	% ls
	atapi_cd.sys	command.com	mailbox.txt	tmp/
	autoexec.bat	config.sys	report.doc

	% cp report.doc ~/documents/
	% rm mailbox.txt
	% rmdir tmp
	
	% eject
	/vol/dev/rdiskette0/no_name: Device busy

	% cd /
	% eject
	/vol/dev/rdiskette0/no_name can now be manually ejected

The 'volcheck' program checks to see if there is a floppy present and
mounts it under /floppy/[DOS disk label].  Since the above disk had no
label, it mounted it under /floppy/no_name.  Once the disk is mounted,
it is accessed as a regular UNIX filesystem.  Finally, the floppy should
be ejected using 'eject' to write any unsaved data on the floppy and 
prevent data loss.  If you get the "Device busy" error, try changing
directory to /, closing any programs you left running that were
either started while you were accessing the floppy or are reading in
files on the floppy, and typing 'eject' again.

While the disk drive is being accessed for reading or writing, the light
in the lower left-hand corner will flash to signify this.  Please do not
attempt to eject the floppy disk while this light is flashing; you may
damage your disk and the drive itself.  Once the disk is ejected using
'eject', press the button on the right-hand side of the floppy drive
to manually eject the floppy disk from the drive.

CD-ROM drives
-------------

To insert a CD-ROM, press the lower right-hand button on the CD
drive unit until the CD drawer opens.  Place your CD label-up within the 
CD drawer. Make sure the CD is level and completely within the drawer, 
then press the left-hand button again to close the drawer.  The drive is 
now ready to use.

Once the CD-ROM is inserted, Solaris will automatically mount the
cdrom under the directory /cdrom.  The contents of the CD-ROM can then
be read using regular UNIX commands.  Once finished, the CD-ROM can be
ejected using the 'eject' command.  The following is a short sample
session on using a CD-ROM.  The session assumes that the CD-ROM has 
already been inserted into the drive.

	% cd /cdrom

	% ls
	cdrom0@ mech2/  

	% cd mech2
	_setup.001*   directx/      instmap1.bwd* mw2help.gid*  smackw32.dll*
	_setup.003*   dset.exe*     keating/      mw2info.txt*  sp16/
	_setup.005*   dsetup16.dll* license.txt*  mw2net.cfg*   start.exe*
	about.fts*    en02star.bwd* mech2/        mystique.par* tech.hlp*
	about.gid*    en03star.bwd* mek/          netlayer.dll* tmp.out*
	archjf.mw2*   en06star.bwd* mw2.adv*      readme.txt*	wail32.dll*
	button.wav*   eregreg2.dll* mw2.phx*      setup.bmp*    

	% cp button.wav ~/sounds/

	% cd /

	% eject

The last 'eject' command should open the drawer, at which time you can
retrieve your CD-ROM.  If you get the 'Device busy' error, try following
the same steps for solving this error as if you were trying to access
a floppy (see the above section on floppy drives).  The CD-ROM drive
will not eject the CD-ROM in response to pushing the left-hand button
if the CD-ROM has not been unmounted by using the 'eject' command.


If you have any questions or problems regarding the floppy disk or CD-ROM
drive, please send email to root@cory.EECS.Berkeley.EDU with a clear 
description of your situation.
