- This BIOS version is for the following computer series:
-
- ------------------------------------------------------------------------
- BIOS Version 5.00 For: T4850CT
- ------------------------------------------------------------------------
-
- This BIOS version is Windows 95 compatible and supports Plug and Play
- functionality.
-
- ******************** BIOS INSTALLATION INSTRUCTIONS ********************
- ************************************************************************
-
- There are two ways to install this BIOS version:
-
- 1) At startup by holding down the F12 key.
-
- 2) Run CHGBIOS.EXE at the command prompt.
-
-
- ********************************** CAUTION! *******************************
- ***************************************************************************
- During the upgrading of your computers BIOS, if the computer loses power or
- fails to complete the process of upgrading the BIOS, the existing BIOS in
- the computer may become damaged. In the event of this occurring, the
- F12 Installation Method, described below, can be used to recover from
- this error condition.
-
- If you are upgrading a number of computers with this BIOS, the F12
- installation method is the quickest but does require a separate low
- density (720 Kb) diskette.
-
-
- 1) F12 INSTALLATION METHOD
- ---------------------------
-
- Your Toshiba computer has a special keyboard function to install an
- updated BIOS image.
-
- IMPORTANT!
- ----------
- To use this function, both the CHGBIOS.EXE program and the BIOS image file,
- BOOTBIOS.COM, must be placed on a LOW DENSITY (720 Kb) diskette. A high
- density (1.44 Mb) floppy disk will not work.
-
- To use this function, hold down the F12 while the computer is powered on.
- The computer MUST be in BOOT mode, not Resume mode.
-
- The F12 installation method will only work with the internal keyboard. If
- your computer is docked with the display closed and are using an external
- keyboard, the computer will need to be undocked and the internal keyboard's
- F12 key used.
-
- When the computer starts up with F12 key depressed, the following
- message appears:
-
- 'Ready for BIOS update. Place the BIOS diskette in the drive, and press
- any key when ready to proceed.'
-
- Insert the 720 Kb diskette that contains CHGBIOS.EXE and BOOTBIOS.COM,
- and press any key. The CHGBIOS program will automatically load the
- BOOTBIOS.COM file.
-
-
- 2) RUN CHGBIOS.EXE AT THE COMMAND PROMPT
- ----------------------------------------
-
- The CHGBIOS.EXE program is designed to be run from the MS-DOS command
- prompt. It cannot be run in a DOS box inside of Windows 3.1x, Windows 95,
- OS/2 or other operating systems. It also will not run if a Memory Manager,
- like EMM386, is loaded. The CHGBIOS.EXE program can be run from a
- floppy disk, hard drive, or PCMCIA drive. However, you will need a floppy
- diskette (high or low density) in your A: drive at the time the CHGBIOS.EXE
- program is run.
-
- When the CHGBIOS.EXE program is executed by itself, it will prompt you
- to specify where the BIOS image file, BOOTBIOS.COM is located. Enter
- the complete path and file name. Example: A:\T215_500\BOOTBIOS.COM.
-
- NOTE!
- -----
-
- If your path for BOOTBIOS.COM is anywhere other than the root directory
- of the A: drive (A:\BOOTBIOS.COM), CHGBIOS.EXE will copy the BIOS image
- file from its current location to the root directory of A: drive.
-
-
- Optionally, the CHGBIOS.EXE program can also be run from a single command
- which includes the path to the BOOTBIOS.COM file.
-
- Example: CHGBIOS D:\T215_500\BOOTBIOS.COM
-
-
- ***************************** CHANGE POINTS ****************************
- ************************************************************************
-
-
- ALL MODELS
-
- DISPLAY SWITCHING
- -----------------
- With Windows 95, the display will switch from the internal display to an
- external display when warm docking onto a Port Replicator, Enhanced Port
- Replicator, or DeskStation. This feature will only work with
- Windows 95.
-
- ALL MODELS EXCEPT: T2400CT/CS,T3600CT,T4700CT/CS,T4800CT,T4850CT
-
- REWORDING OF PARALLEL PORT NAMES IN TSETUP
- ------------------------------------------
- The names of the modes for parallel port have been updated in TSETUP to
- describe their functions in a more understandable way.
- => OUTPUT has been changed to ECP (Enhanced Capabilities Port).
- => Bi-directional has been changed to Std. Bi-Direct.
- This wording does not affect their functionality or the functionality of
- other Toshiba Windows utilities.
-
- However, versions of HWsetup for Windows 3.1x will still indicate the
- old names for the parallel port.
-
-
- ADDITIONAL COMMUNICATIONS PORTS
- -------------------------------
- Two additional Communication Port addresses, COM3 and COM4, have been
- added in TSETUP. HWsetup for Windows 3.1x will not recognize these
- ports as being available. If COM3 or COM4 are selected in TSETUP,
- HWsetup will not show any port being selected.
-
-
- ONLY ON MODELS: T2400CS/CT,T3600CT,T4700CS/CT,T4800CT
-
-
- EIDE HARD DRIVE SUPPORT
- -----------------------
- The BIOS section for hard drive support has been upgraded to support
- Enhanced IDE hard drive . This means that support for hard drives
- larger than 528mb is now available. Check with your local Toshiba Sales
- representative for a listing of compatible hard drives.
-
- ************************ ADDITIONAL INFORMATION ************************
- ************************************************************************
-
-
- UPDATED HOTKEY.DLL
- ------------------
- An additional file called HOTKEY.DLL is included with this BIOS version.
- This file is an update to the Windows 3.1x file that is pre-installed on
- your computer. This file is used by the following Toshiba Windows
- utilities; Maxtime, FN-esse, and Audio Control Windows Sound System.
-
- The existing HOTKEY.DLL provided for Windows 3.1x, causes the Windows 95
- status bar not to be updated when these Toshiba Windows Utilities are
- running.
-
- Please note: Windows 95 will display a warning about the use of
- Maxtime, FN-esse, and Audio Controls. Once the updated HOTKEY.DLL has
- been added, you can check that you don't want to be notified any
- further.
-
- INSTRUCTIONS FOR INSTALLING HOTKEY.DLL
- -------------------------------------
- The existing HOTKEY.DLL file should be located in your Windows directory
- (the default location is C:\WINDOWS). This file should be deleted. The
- updated copy, found on this diskette, should be copied into the Windows
- system subdirectory (usually C:\WINDOWS\SYSTEM).
- Please note that you cannot delete the old file while Maxtime, FN-esse,
- or Audio Controls are running (these programs use this file).
-
- After copying this file in, you should Restart Windows for the file
- change to take effect.
-
- ********************** Additional Windows 95 Tips **********************
- ************************************************************************
-
-
- T4900CT/T4850CT-800/610CT/400CS/CT MODELS ONLY
- ----------------------------------------------
- Prior to installing Windows 95, disable 32-bit Hard Drive access under
- Windows 3.1x. (Follow this procedure: Go to the Main window in Program
- Manager, select Control Panel, select 386 Enhanced, and click on Virtual
- Memory. Change and unmark the check box for 32-bit Disk Access)
- This is because the Toshiba provided 32-Bit Hard Drive Access driver
- prevents the hard drive from being reported correctly in the Windows 95
- Device Manager.
-
- There is no need to modify the Windows 3.1x SYSTEM.INI file to remove
- the driver.
-
-
- COMPUTERS EQUIPPED WITH ACCUPOINT POINTING DEVICES
- --------------------------------------------------
- The Logitech mouse driver v6.32 provided with these models and its
- features provided with these computers is designed for Windows 3.1x and
- can cause some erratic behavior in Windows 95. Specifically, the Enable
- Tracking option in Logitech Cursor Enhancement does not function
- correctly under Windows 95.
-
-
- COMPUTERS WITH ESS AUDIO CARDS
- ------------------------------
- Windows 95 will show a setting for a Joystick both in the Control Panel
- and in the Device Manager upon the first boot up on Computers with an
- ESS Audio card if installed in an "undocked" state. After shutting down
- the computer, and restarting, the Joystick is reported correctly. If
- Windows 95 is installed when the computer is "docked" to the Port
- Replicator, the Joystick is set correctly.
-
-
- COMPUTERS WITH EXTERNAL FLOPPY DRIVES THAT ARE NOT ATTACHED
- -----------------------------------------------------------
- You will receive an error message at the end of the installation as
- Windows 95 restarts, reporting that there is a floppy diskette in the
- floppy disk drive. Press <OK> to continue with the installation.
-
-
- DEMO PROGRAMS ARE MISINTERPRETED AS SCREEN SAVER PROGRAMS
- ---------------------------------------------------------
- Some Toshiba Sales Demo programs are misinterpreted by Windows95 as a
- screen saver program. The demo program will function as a screen saver
- program, except that mouse movements and mouse buttons do not recover
- the screen. Only a keyboard entry will recover the screen.
-
-
- UNKNOWN MONITOR AFTER DOCKING
- -----------------------------
- If the LCD display is set up as a Laptop Display Panel in the "undocked"
- state, when the computer is "docked", the Monitor type will come up as
- an Unknown monitor.
-
-
- SECOND PCMCIA CONTROLLER APPEARS IN DEVICE MANAGER
- --------------------------------------------------
- When Windows95 is installed in the "undocked" state and then "docked" to
- a Port Replicator or DeskStation, a second 'PCIC or Compatible PCMCIA
- Controller' may be listed in Device Manager. Delete the second
- controller from Device Manager.
-
- If the computer is "docked" to an Enhanced Port Replicator, it should
- report a second 'PCIC or Compatible PCMCIA Controller' because there is
- one located inside the Enhanced Port Replicator.
