"STOP 0xA" Occurs After Applying Windows NT 4.0 Security Rollup Package

After you apply the Windows NT 4.0 Security Rollup Package (SRP) and restart a computer that has one of the following Compaq Smart Array controllers, you may receive an error message on a blue screen:

• Compaq SMART Array controller
• Compaq SMART-2/E Array controller
• Compaq SMART-2/P Array controller
• Compaq SMART-2DH Array controller
• Compaq SMART-2SL Array controller
• Compaq Smart Array 3200 controller
• Compaq Smart Array 3100ES controller
• Compaq Smart Array 221 controller

This is the error message that you may receive: In this error message, the memory that is referenced is 0xfcc35000. The IRQL is 0xa (IRQ 10). Value 0 is a read operation; 1 is a write operation. The address that referenced memory is 0x801e092a.

The Windows NT 4.0 SRP exposes an issue with versions earlier than 4.24.0.0 of the Compaq Array Controller device driver (Cpqarray.sys) that is available from any of the following sources:

• Compaq Web site: Compaq Server Support (SSD) for Microsoft Windows NT 4.0
• Compaq SmartStart and Support Software CD-ROM
• Compaq SmartStart for Servers

For additional information about these packages, visit the Compaq Web site:

To resolve this issue, obtain the updated version of the Cpqarray.sys driver from the following Compaq Web site: Microsoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.

To prevent this problem from occurring, install the updated Cpqarray.sys driver before you install the SRP.

If you cannot obtain the updated Cpqarray.sys driver that is described earlier in this article, you can work around this issue by replacing the existing Cpqarray.sys file with the version from Microsoft Windows NT 4.0 Service Pack 6a (SP6a):

1. If the partition uses the NTFS file system, install Windows NT in a different folder so that the files in the partition are accessible.
   
   If the partition uses the FAT file system, start the computer by using an MS-DOS boot disk, and then skip to step 3.
2. Boot the computer to the new installation of Windows NT.
3. Copy the Cpqarray.sys file from Windows NT 4.0 SP6a to the original Windows NT 4.0 folder (%SystemRoot%\System32\Drivers).
4. You may also use the Recovery Console from Windows 2000 to rename the offending driver and replace it with CPQARRAY.SYS from SP6a.

As an alternative, you can use the Scsiport.sys file from Windows NT 4.0 SP6a to start your computer. This causes several fixes that are included with the Windows NT 4.0 Security Rollup Package to be removed. The advantage to using this method is that any additional functionality that is included in the Compaq version of the Cpqarray.sys driver is available. To replace the Scsiport.sys file, use the preceding steps, but copy the Scsiport.sys file instead of the Cpqarray.sys file.
