RETROFIT.TXT v1.1 08-18-1998 CDC ============================================================================== RETROFITTING ACPI BIOS AFTER WINDOWS 98 IS INSTALLED This document ONLY applies if you have installed Windows 98 without having the ACPI BIOS already installed on your system. Toshiba recommends installing this ACPI BIOS prior to upgrading or installing Windows 98. If this is not possible, the following procedure will allow you to update your Windows 98 installation for ACPI functionality. The short list of procedures is presented below, followed by detailed instructions. To successfully complete this process, you'll need to download APMACP98.EXE from Toshiba's Services and Support Website. The direct download URL to this file is http://www.csd.toshiba.com/tais/csd/support/files/download/apmacp98.exe 1. Download APMACP98.EXE from Toshiba's Online Services, and make certain to copy it to your Win98 machine 2. Shutdown the system install the ACPI BIOS 3. Reboot to Windows 98 4. From Win98 Explorer, double-click on the icon for the APMACP98.EXE file that you downloaded. 5. *After Windows 98 restarts, copy the SERWAVE.VXD file from the \UNIMODEM\ folder on the Applications CD-ROM to the \Windows\System\ folder. On some systems, this file may be hidden, so you can use Win98's "Find" function to locate the file. *Steps marked with an asterisk only apply to models equipped with internal modems. These steps do not apply to models that use a PCMCIA modem DETAILS: 1. Download APMACP98.EXE from Toshiba's Online Services, and make certain to copy it to your Win98 machine 2. Install the ACPI BIOS using one of the methods described in the BIOS installation instructions (README.TXT). 3. Restart your computer and allow Windows 98 to load normally 4. From Win98 Explorer, double-click on the icon for the APMACP98.EXE file that you downloaded. This will cause Windows 98 to scan for new hardware (ACPI). This process will require several reboots, and will find many "new" hardware devices, installing drivers for each. If Windows prompts you with questions about unknown devices, just press Enter through the prompts. You can install drivers for these items later. Drivers for some "Unknown Devices" will be provided in the Toshiba Win98 Utilities for your machine. When this process is complete, proceed to step 5. 5. Windows 98 insists on installing its own version of the "Wave device for voice modem". This driver is likely to cause your internal modem-equipped Toshiba notebook to lock up when Windows restarts, or will cause problems (lockups) when using the modem. The simple fix for this is to rename the existing version of \Windows\System\SERWAVE.VXD to SERWAVE.W98 and then copy the SERWAVE.VXD file from the \UNIMODEM\ folder on the Applications CD-ROM to the \Windows\System\ folder. You can do this from Windows 98 Explorer (in "Safe Mode" if your system hangs up on restart), or from the command prompt. It might be a good idea to copy this file to a diskette if you need to apply the fix from Safe Mode, since Safe Mode doesn't provide CD-ROM support. **end**Download Driver Pack
