MultiSafe Security System

Source:TEG PM

MultiSafe is an advanced security system which allows up to four users access to the computer, each with a different password. It can also be used to limit access to certain technical features. Because it is built into the circuitry of the motherboard, it is next to impossible to subvert the security system without destroying the computer. The access data for MultiSafe are stored in an EEPROM chip, so that they can always be rewritten.

Using passwords

The password used to gain access to the computer when it boots is called the power-on password. In addition MultiSafe includes a hot key instant security lock for short pauses in work. This causes the screen

to blank and the keyboard and mouse no longer allow any data entry until the instant security password has been entered. This can be the same as the power-on password or different. Both can be up to 16 characters long, including numbers, but excluding symbols and punctuation marks.

MultiSafe also controls the use of the disk drives and the serial, parallel and PCMCIA ports on the T4-Series. Each of these can be blocked to stop an individual user accessing it. The only restriction is that it is not possible to block both the floppy disk drive and the hard disk at the same. This is because one must be available for booting the computer.

Controlling MultiSafe Control of MultiSafe rests with the user designated as the Supervisor. At least one user must always have this designation. Other users are allocated "change of password" or "no privilege" levels. The utility PWSETUP.EXE on the Diagnostic and Supplemental diskette is needed to setup and change settings in MultiSafe. It can be loaded onto the hard disk via the Access program. Access to PWSETUP.EXE is controlled by the power-on password.

The supervisor can change any of the settings in PWSETUP.EXE, both his own and those of the other users. He can also change passwords. "Change of password" status allows a user to change his own password but nothing else. A "No privilege" status user can only view the details of his access rights but not change anything.

If you are testing a computer from Toshiba you may be given a password for access. This will let you look at the MultiSafe setup utility. If you have a new PC for testing and you have full Supervisor rights to set up

passwords, please do no forget to remove it before handing the computer back.
