SYMPTOMS
When you try to resume your computer from Standby or Suspend mode, your Personal Computer Memory Card International Association (PCMCIA) Small Computer System Interface (SCSI) controller may stop responding. Also, if you view this device in Device Manager, it may be listed as Disabled with the following status:

  The device cannot find any free Interrupt Request (IRQ) resources to   use (Code 12).



CAUSE
This problem can occur if your computer is resumed from Standby or Suspend mode multiple times without being restarted, and the Drvwppqt.vxd file is the Windows\System\Iosubsys folder.



RESOLUTION
To work around this problem, restart your computer, and then use either of the following methods:

Method 1
Do not resume your computer from Standby or Suspend mode multiple times without restarting your computer.

Method 2
Rename the Drvwppqt.vxd file, and then restart your computer. To do so, use the following steps:

NOTE: Do not perform the following steps if you have a tape backup device connected to a parallel (LPT) port on your computer.


 * 1) Click Start, point to Find, and then click Files Or Folders.
 * 2) In the Named box, type "drvwppqt.vxd" (without quotation marks), and then click Find Now.
 * 3) Rename all instances of this file by changing the file name extension. To rename a file, right-click it, type the new file name, and then press ENTER.
 * 4) Restart your computer.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 98.



MORE INFORMATION
The Drvwppqt.vxd file is installed if Microsoft Backup is installed, and is used to communicate with parallel-port tape backup devices. Note that if you uninstall Microsoft Backup, this file is not removed.

The Drvwppqt.vxd file may also be installed as a part of the Seagate Backup software. In this case, renaming the file may interfere with proper functioning of the Seagate Backup software, especially if you are using a parallel-port tape backup device. If you are using Seagate Backup, please contact Seagate for additional information about the Drvwppqt.vxd file.

This problem has been reported to affect the following PCMCIA SCSI controllers:
