------------------------------------------ Toshiba Companion Diskette ------------------------------------------ The following topics are discussed in this file: 1. Windows 3.x and Special Toshiba features 2. 386 Expanded Memory Managers and Special Toshiba features 1. Windows 3.x and Special Toshiba features -------------------------------------------- Users have encountered problems with special Toshiba features when using Windows 3.x on battery-powered 386/486 Toshiba PCs. Often, these problems are related to Windows 3.x being unaware of certain areas of memory needed to support Toshiba-specific functions such as RESUME, HardRAM, and battery-saving features. The simplest way to avoid the conflict over these memory areas is to prevent Windows 3.x from using these particular ranges of addresses for any purpose. The following table shows the address ranges you should exclude for your particular Toshiba model and features you wish to use: ------------------------------------------------------------ Toshiba Computer Segment Address Range to Exclude Model(s) ------------------------------------------------------------ T3100SX Exclude E000-E7FF if you plan to use T2000SX HardRAM. T2000SXe T2200SX Exclude E800-EFFF if you plan to use T4400SX RESUME, or any battery-saving features. T1800 series T4500 series If you need to exclude both E000-E7FF T100X and also E800-EFFF, you may specify this as a single range E000-EFFF. ------------------------------------------------------------ T3300SL Exclude C800-CFFF if you plan to use HardRAM, RESUME, or any battery-saving features. ------------------------------------------------------------ T1900 series Exclude E000-E7FF if you plan to use HardRAM. Exclude C800-CFFF if you plan to use RESUME, or any battery-saving features. ------------------------------------------------------------ T4600 series Exclude c800-cfff if you plan to use RESUME, or any battery-saving features. ------------------------------------------------------------ T1910 series T1950 series Exclude E800-EFFF if you plan to use T3400 series RESUME, or any battery-saving features. T4700C series T4800CT ------------------------------------------------------------ Examples: You have a T2200SX and you plan to use RESUME but not HardRAM. You should: 1. Use TEST3.EXE to set your HardRAM size to 0KB. 2. Add a EMMExclude=E800-EFFF command to the [386Enh] section of your Windows SYSTEM.INI file. You have a T4400SX and you plan to use all special Toshiba features. You should: 1. Add a EMMExclude=E000-EFFF command to the [386Enh] section of your Windows SYSTEM.INI file. You have a T3300SL and you plan to use only the battery- saving features. You should: 1. Add a EMMExclude=C800-CFFF command to the [386Enh] section of your Windows SYSTEM.INI file. You may use Notepad to edit the SYSTEM.INI file. If you are using a 386 Expanded Memory Manager other than Toshiba's EMM386.EXE, you will need to repeat the Toshiba excluded address ranges in your memory manager setup. It is necessary to repeat the same exclusion within your memory manager because there is no mechanism for a memory manager (either Toshiba or third-party) to communicate the range of excluded segment addresses to Windows. Toshiba supplies a driver file (WRESUME.386) that allows the RESUME feature of your computer to function correctly when running Windows 3.x in 386-enhanced mode. This resume driver found on the Toshiba Companion diskette. 2. 386 Expanded Memory Managers and Special Toshiba features ---------------------------------------------------- Many 386 Expanded Memory Managers allow you free up application memory by loading device drivers and TSRs into high memory. Toshiba's EMM386.EXE includes this functionality and has been specially modified to be compatible with all special Toshiba features (including RESUME). Users have encountered problems with special Toshiba features when using third-party (non-Toshiba) expanded memory managers on battery-powered 386/486 Toshiba PCs. Often, these problems are related to the memory managers being unaware of certain areas of memory needed to support Toshiba-specific functions such as RESUME, HardRAM, battery- saving features. The simplest way to avoid the conflict over these memory areas is to prevent your memory manager from using these particular ranges of addresses for any purpose. Note: Toshiba's EMM386.EXE automatically excludes the proper address ranges by default, so there is no conflict with any Toshiba-specific functions. The following table shows the address range you should exclude for your particular Toshiba model and features you wish to use: ------------------------------------------------------------ Toshiba Computer Segment Address Range to Exclude Model(s) ------------------------------------------------------------ T3100SX Exclude e000-e7ff if you plan to use T2000SX HardRAM. T2000SXe T2200SX Exclude e800-efff if you plan to use T4400SX RESUME, or any battery-saving features. T1800 series T4500 series If you need to exclude both e000-e7ff T100X and also e800-efff, you may specify this as a single range e000-efff. ------------------------------------------------------------ T3300SL Exclude c800-cfff if you plan to use HardRAM, RESUME, or any battery-saving features. ------------------------------------------------------------ T1900 series Exclude E000-E7FF if you plan to use HardRAM. Exclude C800-CFFF if you plan to use RESUME, or any battery-saving features. ------------------------------------------------------------ T4600 series Exclude c800-cfff if you plan to use RESUME, or any battery-saving features. ------------------------------------------------------------ T1910 series T1950 series Exclude E800-EFFF if you plan to use T3400 series RESUME, or any battery-saving features. T4700C series T4800CT ------------------------------------------------------------ The following examples illustrate some specific situations using the above table. They provide parameter settings for both QEMM-386 and 386MAX. Example: You have a T2200SX and you plan to use HardRAM and have disabled RESUME, and all battery-saving options. You should: Specify X=E800-EFFF in your QEMM-386 setup. Specify EXCLUDE=E800-EFFF in your 386MAX setup. Example: You have a T3300SL and you plan to use only the battery-saving features and have disabled HardRAM. You should: Specify X=C800-CFFF in your QEMM-386 setup. Specify EXCLUDE=C800-CFFF in your 386MAX setup. For other memory managers, refer to the your documentation for instructions on how to exclude specific address range(s). If you are using Windows 3.x, you will need to make sure that Windows does not attempt to use the Toshiba excluded areas. See the topic, "Windows 3.x and Special Toshiba features" earlier in this file for more information. Toshiba supplies a driver file (VRESUME.SYS) that allows the RESUME function of your computer to function correctly when running under control of memory managers such as QEMM-386 and 386MAX. The resume driver is found on the Toshiba Companion Diskette.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
