Usage instructions for USB attached storage with DFSee and FreeDOS

The DOS environment normally does NOT support modern devices like
USB memory sticks or USB attached hard disks. This means that such
devices can not be analysed or recovered using DFSee, nor can they
be used to store logfiles, analysis files or images.

With the addition of 3rd party device-drivers however, it IS possible
to add that support to a DFSee DOS based bootable diskette or CDROM.

Several drivers are available from hardware manufacturers that will
support their own, and often other hardware as well.

A problem with using these may be copyright or licensing issues.

Redistribution of these drivers in a commercial package is not
allowed as far as I have been able to check, but download and
usage by individuals does not seem to be a problem since the
drivers are available from free accessible support sites.

This is the reason that suitable drivers are NOT included in the
standard DFSee distribution. YOU will have to get the required
driver files from the Internet and add them to the diskette.
Any consequences of using those drivers lies with the end USER only.
In no way Fsys Software shall be held liable.


However, since some drivers are widely used and available from various
places on the Internet, some configuration required to use these drivers
have been added to the DFSee bootable diskette based on FreeDOS.

The drivers tested with FreeDOS and DFSee are:

 usbaspi.sys            Panasonic Communications Co. (tested 2.06 and 2.20)
 ramfd.sys              Panasonic Communications Co. (tested 1.03)
 di1000dd.sys           NOVAC Co.                    (tested 2.00)

All drivers have a copyright set by their respective owners.

A search with Google for these (and perhaps 'download' :-) should get
you plenty of places to get them from, including the Panasonic support
site itself.

The RAMFD driver is needed only if you have a single USB connection, that
is needed to boot from the diskette as well as attaching a storage device.
It will boot first from diskette, and transfer the diskette contents to
a ram-disk and then allow you to attach the other USB medium.

The DI1000DD driver is needed if you want to have access to the partitions
on the attached USB medium through a driveletter. This is needed to store
logfiles or read/write imagefiles to the USB medium.

If you just need to analyse or recover a USB storage medium, the USBASPI
driver is all you need to access it as a physical disk within DFSee.

After adding the driver files to the root-directory of the diskette, you
can use the (otherwise undocumented) boot-menu items (8) and (9) from
the blue boot-menu presented when you boot the diskette.

Selection (8) is for normal use, and (9) will allow booting from an USB
attached floppy (if supported by BIOS) and swap that for the USB storage
medium after booting.


When working properly, with the USBASPI and DI1000DD drivers in place,
the USB storage device(s) should become visible in DFSee as additional
physical disks, and any FreeDOS recognized partitions (FAT, FAT32)
should be available through the file-dialogs and commands as regular
drive-letters for logfile and imagefile use.
