Quadtel BIOS Versions to Use with Windows

• Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11

SUMMARY

Quadtel BIOS version 3.05.xx (where xx is the type of chip set used by this computer) dated 12/18/90 or later is recommended for use with Microsoft Windows. If you use an earlier BIOS version, your system may hang when running Windows versions 3.0 and 3.0a in real, standard, and enhanced modes, and when running Windows 3.1 in standard and enhanced modes.

Some releases of the Quadtel BIOS have a CMOS screen saver utility that may need to be disabled or the screen may blank during Windows' setup. To access the CMOS utilities, press CTRL+ALT+S.

Austin Computers

On all Austin 386 machines with dual hard disk drives (normally dual IDEs), Quadtel BIOS version 3.05.02 or greater is needed for Windows 3.0.

MORE INFORMATION

Quadtel makes a modular BIOS that is used by OEM computer manufacturers and can be modified by an OEM under a license agreement with Quadtel.

To find the Quadtel BIOS date:

1. Type "debug" (without the quotation marks).

2. At the - prompt, type "dffff:5 18" (without the quotation marks). BIOS date is displayed on the right side of the screen.

3. At the - prompt, type "q" (without the quotation marks) to quit.

If the Quadtel BIOS is version 3.04.xx or 3.05.xx dated 12/18/90 or earlier and you are using more than one user-defined hard drive (for example, IDE), upgrade the BIOS to version 3.05.xx dated later than 12/18/90 to prevent Windows 3.0 from hanging.

Quadtel BIOS upgrades are handled by the OEM computer manufacturers. Call your computer manufacturer for BIOS upgrade information.
