PCMCIA Cards Detected Twice on IBM ThinkPad 750 and 750c

= SYMPTOMS =

On the IBM ThinkPad 750 and 750C, PCMCIA cards are reported as two separate nodes under the Device Manager card class.

= CAUSE =

When the Socket Services driver attempts to determine the number of PCMCIA sockets in the ThinkPad, the ThinkPad incorrectly reports that there are more than two PCMCIA sockets, even though the ThinkPad has only two.

= WORKAROUND =

To work around this problem:


 * 1) Click the Start button, point to Settings, then click Control Panel.
 * 2) Double-click the System icon, and then click the Device Manager tab.
 * 3) Expand the PCMCIA Socket branch and click “Intel PCIC Compatible PCMCIA Controller.”
 * 4) Click the Properties button, then click the Socket Services tab.
 * 5) In the Number Of Sockets box, change the value from Automatic Detection to 2.
 * 6) Click Apply Now on all open property sheets, then click Shut Down on the taskbar and restart Windows 95.

Now any PCMCIA card you plug in will be detected only once.

If you already have two instances of a PCMCIA device in Device Manager, select the class of the card (for example, Modem or Network), expand the branch and remove one of the instances of that device.
