README.TXT 8-15-95 This BIOS version is for the following computer series: ------------------------------------------------------------------------ BIOS Version 5.00 For: T2130 series and T2110 series Compatible models: T2130CT, T2135CT, T2130CS, T2135CS, T2110CS, T2115CS ------------------------------------------------------------------------ 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 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. *** END OF FILE
