SYMPTOMS
When you insert a PCMCIA disk drive into a PCMCIA slot, your computer beeps, indicating that the PCMCIA card is recognized, but the disk drive is unavailable in Windows 95.

CAUSE
A resource conflict may exist if the PCMCIA disk controller is configured to use I/O ports 170-177 and your computer uses the same ports for some other purpose.

RESOLUTION
Examine the computer settings in Device Manager. If the PCMCIA disk controller is using ports 170-177, try either of the following methods to resolve the conflict:

 Reserve I/O ports 170-177, forcing Windows 95 to configure the PCMCIA disk controller at another I/O address. To do so, follow these steps:

 In Control Panel, double-click the System icon. On the Device Manager tab, click Properties. On the Reserve Resources tab, click the Input/Output (I/O) option button, and then click Add. In the Start Value box, enter 170. In the End Value box, enter 177. Click OK until you return to Control Panel Restart your computer.</li></ul>

Windows 95 will not configure any device to use I/O ports 170-177 if it can avoid doing so.</li> Try disabling any secondary disk controller that uses I/O ports 170-177 in the computer's CMOS settings.</li></ul>
