********************************** 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
BIOS Key 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 BIOS Key
installation method is the quickest.
It is recommended that all PCMCIA cards be removed from the system prior to
upgrading the BIOS. Also recommended is detaching the computer from any
docking device (Desk Station, port replicator, etc.) which may be attached.
It is not unusual to see a CMOS error when you first reboot the computer after
installing the new BIOS. If you see this message on your screen, press F1 as
instructed. This displays the "TSETUP" screen. Press <End> to save the CMOS
data. You won't see the CMOS error again.
******************** BIOS INSTALLATION INSTRUCTIONS *************************
*****************************************************************************
There are three ways to install this BIOS version:
1) Use the bootable diskette that is automatically created by the Windows
UnZip process (Recommended)
2) Hold down the BIOS installation hot key while the computer is being
powered-on (see below).
3) Run CHGBIOSA.EXE at the command prompt.
*****************************************************************************
1) BOOT DISKETTE INSTALLATION METHOD (Recommended)
--------------------------------------------------
This release of the electronic distribution BIOS utilizes a self-extracting
ZIP file that, when run under Windows or Win-OS2, creates a bootable BIOS
installation diskette.
Since you're reading this, you were obviously able to extract the downloaded
file. If you also created the BIOS installation diskette as a part of the
extraction process, you're ready to follow the installation instructions
below.
If you didn't create the installation diskette during the extraction phase,
or if you extracted the downloaded file with PKUnZip or WinZip, you can
create the installation diskette by executing the INSTINFO program from the
DOS command prompt.
Install this BIOS using the following steps:
WINDOWS 9x, Me, XP, 2000, NT:
o Close all open programs
o Insert the BIOS installation diskette into your diskette drive (A:)
o Click Start
o Click Shutdown
o Select Shutdown from the list of available options
o Click OK or Yes to confirm
WINDOWS 3.x:
o Close all open programs
o From Program Manager, click on File/Exit Windows
Windows exits to a MS-DOS command prompt
o Insert the BIOS installation diskette into your diskette drive (A:)
o Press Ctrl-Alt-Del (press and hold the <Ctrl> and <Alt> keys and press
the <Del> key) to restart the system
OTHER OPERATING SYSTEMS
o Close all open programs
o Shut down the operating system
o Insert the BIOS installation diskette into your diskette drive (A:)
o Restart the computer by pressing Ctrl-Alt-Del or turning the computer
OFF then on again
The computer will boot MS-DOS from the BIOS installation diskette, and
initiate the Flash BIOS installation routine. Please note that on systems
where only a USB-connected diskette drive is supported, you can force the
computer to boot from the USB-connected diskette by holding down the "U" key,
when powering-on the system.
When the Flash BIOS installation is complete, the success message is displayed:
Please push the RESET SW (or turn AC power OFF/ON) to restart!
ROM Write Successful!
Utility Finished!
Eject the diskette from drive A: and turn the computer OFF then ON, or press
the reset switch to restart your computer.
ADDITIONAL INFORMATION REGARDING THIS RELEASE
---------------------------------------------
If you are unable to use the Windows self-extractor, the self-extracting
ZIP archive can be extracted by executing it from a DOS prompt or it can be
extracted using PKUNZIP 2.04G or an equivalent UnZIP utility. A DOS batch
file, INSTINFO.BAT is provided in the ZIP archive which will create the BIOS
installation diskette. If all else fails, you can execute the
self-extracting diskette image manually. This file is named 1340D190.EXE, and
needs a parameter of A: (1340D190 A:) to successfully create the diskette in
drive A:
The self-extracting diskette image, 1340D190.EXE, will run under MS-DOS or a
command prompt under Windows 9x, Me, 2000, NT, or OS/2. PLEASE NOTE that long
directory names in the path where the self-extracting image file is stored
under Windows 9x or NT/2K will cause the self-extracting image to abort. Long
directory names are supported under OS/2.
2) BIOS KEY INSTALLATION METHOD
---------------------------
Your Toshiba computer has a special keyboard function to install an
updated BIOS image. The term "BIOS key" below refers to the F12 key
on your system's keyboard.
To use this function, hold down the BIOS key while the computer is
powered on. The computer MUST be in BOOT mode, not Resume mode.
This installation method will only work with the internal keyboard. If
your computer is docked with the display closed and you are using an external
keyboard, the computer will need to be undocked and the internal keyboard's
BIOS key used.
When the computer starts up with the BIOS 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.'
On some models (Satellite 5005 and others) where a system status LCD is
included, this and all messages displayed during the BIOS key installation
processs will appear in the system status LCD rather than on the main
display panel.
Insert the diskette that contains CHGBIOSA.EXE and BIOFC64T.COM,
and press any key. The CHGBIOSA program will automatically load the
BIOFC64T.COM file.
3) RUN CHGBIOSA.EXE AT THE COMMAND PROMPT
-----------------------------------------
The CHGBIOSA program is designed to be run from the MS-DOS command
prompt. It cannot be run in a DOS box inside of Windows 3.x, Windows 9x,
OS/2 or other operating systems. It also will not run if a Memory Manager,
like EMM386, is loaded. The CHGBIOSA 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 CHGBIOSA
program is run.
When the CHGBIOSA program is executed by itself, it will prompt you
to specify where the BIOS image file, BIOFC64T.COM is located. Enter
the complete path and file name. Example: C:\1180V19\BIOFC64T.COM.
NOTE!
-----
If your path for BIOFC64T.COM is anywhere other than the root directory
of the A: drive (A:\BIOFC64T.COM), CHGBIOSA will copy the BIOS image
file from its current location to the root directory of A: drive.
Optionally, the CHGBIOSA program can also be run from a single command
which includes the path to the BIOFC64T.COM file.
Example: CHGBIOSA C:\1180V19\BIOFC64T.COM
CHANGE HISTORY
--------------
Version 1.90 10-23-2001
o A change was made to support a touchpad.
o The temperature parameter as a measure for heat was changed.
o A change was made to correct a display controller boot failure. The
boot block was changed from V1.10 to V1.20.
o If a non CD-ROM model in which no data of destination and with or
without CD-ROM information in DMI data were entered in the
manufacturing proccess, the machine will take about 4 minutes to boot
after disconnecting the CD-ROM drive. A change was made so that the
machine will be recognized as a non CD-ROM model by booting the
machine while pressing the "/" key.
o A function was added to update the boot block from V1.10 to V1.20.
The flash part of the BIOS remains at V1.90.
Version 1.80 08-01-2001
o A countermeasure was taken against a problem that caused some CPU's of
the 1805-S273 (those with a CPU 1GHz) to have problems when they
reached shut down temperature. This was due to an inconsistent power
consumption of the CPU, even if the CPU temperature was controlled.
Version 1.70 08-01-2001
o In order to support 1GHz CPU this BIOS incorporates changes to address
temperature control.
o Corrected a problem that, when the computer goes into S4/S5 state
(S4+Hibernation, S5=Power Off) the CMOS data would get corrupted.
o Corrected a problem that caused the computer to take an extended
amount of time to shut down after going into Hibernation.
Version 1.50 07-10-2001
o A change was made to correct a problem that some PC cards with a
single spec for 16 bit and 3.3VDC may malfunction.
Version 1.40 06-15-2001
o Corrected an issue where, when restarting Windows 2000, if the CPU
speed is lowered by throttling, the system may hang.
o A workaround was applied against a possible problem where, when
running under Windows 2000, and resuming from Hibernation Mode, with
the Battery remaining charge at Critical state, the system may hang.
Version 1.30 06-08-2001
o Initial production release for Satellite 1800/1805-S203/S253
