TECHNICAL NOTE (96002)

Summary:	CryptCard Security System for Toshiba Notebooks
Date:	September 29, 1995
Product:	As listed
Problem / Issue:	General Information & Usage
Solution:	See below
Additional Information:	None

PART 1: General information about the installation process:

I. CCSETUP.EXE:

This program allows for performing all functions of loading firmware, (contained in the file CCCODE01.PRP) customizing CryptCards, edit and load user profiles, install and deinstall the security system. The file CCLANG.OVR contains all messages displayed when using CCSETUP.EXE. When using CCSETUP.EXE, the very important file SECURITY.DAT is created, containing all data necessary to maintain and update the CryptCard security system.

A few comments on CCSETUP:

a) CCSETUP and CryptCard itself need a free memory window at C800-D1FF. Make shure, that the EMM386.EXE is not activated in your CONFIG.SYS or that the EMM386 runs with the optional parameter X=C800-D1FF. The EMM386 statement of your CONFIG.SYS should look like the following:

DEVICE=C:\DOS\EMM386.EXE NOEMS X=C800-D1FF

b) All functions but <edit profiles>, <Generate Profile Template>,

and <Customize Update Firmware> from the menu 'manual setup' require the CryptCard. If the CryptCard is needed the program must be started on notebook equipped with the Toshiba security BIOS.

II. When having installed the security system, you can use the program CCFD.EXE to display the floppy status and to change between ciphered and plain operation if this is allowed. When calling CCFD.EXE with either the switch '/c' or '/p' the floppy status is changed to ciphered or plain, respectively and neither any message nor any prompt is displayed.

III.The program READLEVL.EXE can be used to control batch processes. It returns the CryptCard's batch parameter into the DOS variable 'errorlevel'.

IV. Use TOSHPW.EXE to change your TOSHIBA instant password (hotkey function).

PART 2: Instructions for using the CryptCard with OS/2 2.x:

The present software package contains both an OS/2 driver which handles the hard disk encryption and an OS/2 utility similar to CCFD which allows to change the floppy mode between ciphered and plain.

IMPORTANT!

Although the CryptCard driver CCRYPT.FLT fully supports all OS/2 con- figurations including HPFS partitions, the actual installation of the CryptCard (i.e. the initial dard disk encryption) MUST be carried out with CCSETUP.EXE under DOS (do not use a DOS box of OS/2)!

For installation of the CryptCard proceed as follows:

1. Install OS/2 first.

2. Copy the file 'CCRYPT.FLT' of the CryptCard Installation Disk into the subdirectory '\OS2' of your OS/2

boot partition.

3. Append the following line at the end of the CONFIG.SYS of OS/2:

BASEDEV=CCRYPT.FLT

4. Start DOS (from a diskette or another partition) and run CCSETUP.EXE to install the CryptCard

according to the CryptCard User's Guide.

!!! DO NOT use an OS/2 DOS box for the installation of CryptCard !!!

5. Start OS/2. Now the system runs as usual.

6. After having installed the security system, you can use the program CCFDPM.EXE to display the floppy

status and to change between ciphered and plain operation if this is allowed. CCFDPM.EXE is the OS/2

PM Version of the DOS program CCFD.EXE.

When calling CCFDPM.EXE with either the switch '/c' or '/p' the floppy status is changed to ciphered or plain, respectively without displaying any message (if no other instance of this program is currently running).
