IBM Thinkpad 770 Stops Responding When You Start Windows 98

• Microsoft Windows 98

SYMPTOMS

When you try to start your Windows 98-based IBM ThinkPad 770 laptop computer, your computer may stop responding (hang).

CAUSE

This behavior can occur if the Csmapper.sys file is being loaded from the Config.sys file. The Csmapper.sys file prevents the use of linear-flash and synchronous random-access memory (SRAM) Personal Computer Memory Card International Association (PCMCIA) cards that use MS-DOS real-mode drivers. Because your computer is unable to access this type of memory, you may experience this behavior.

RESOLUTION

To resolve this issue, remove the real-mode drivers, and then install protect-mode drivers. To do so, use the following steps:

1. Restart your computer and press and hold the CTRL key. From the Startup Menu, choose Command Prompt Only.



2. Type edit config.sys, and then press ENTER.



3. Type rem at the beginning of the lines that reference the Csmapper.sys and Carddrv.exe files.



4. Press ALT+F, press S, press ALT+X, and then press ENTER.



5. Restart your computer.



6. Insert your Windows 98 CD-ROM into your CD-ROM drive.



7. Click Start, point to Find, and then click Files Or Folders.



8. Click your CD-ROM drive in the Look In box, and then click Find Now.



9. Right-click the Trueffs.inf file, and then click Install.
