STOP 0xC0000263 When Upgrading to WinNT 3.51 On Compaq Computers

The information in this article applies to:

• Microsoft Windows NT Workstation version 3.51
• Microsoft Windows NT Server version 3.51

SYMPTOMS

After you upgrade a Compaq computer with Microsoft Windows NT 3.51 and restart the computer, the following STOP error message appears:

   STOP: 0xC0000263 {Driver Entry Point Not Found}
   The \SystemRoot\system32\drivers\Sysmgmt.sys device driver
   could not locate the entry point HalCPQShareInt13
   in driver hal.dll.

CAUSE

This problem occurs if the Compaq Insight Management Agent is not disabled before you perform the upgrade.

RESOLUTION

To work around this problem:

1. Restart your computer with another installation of Windows NT 3.51 or another operating system. The Compaq Insight Management Agent file SMSMGMT.SYS is located in the %SystemRoot%\System32\Drivers directory. If this directory is in the NTFS partition, you must use another installation of Windows NT.

2. Rename SYSMGMT.SYS to another file name.

3. Restart the upgraded version of Windows NT. The Insight Management Agent fails to load and an error message appears.

4. Load the Compaq Hardware Abstraction Layer (HAL) with the entry point for SYSMGMT.SYS from the latest Compaq Support Software Diskette (SSD), or enable the the Insight Management Agent by renaming the agent file back to SYSMGMT.SYS. The Compaq SSD loads a newer version of the SYSMGMT.SYS.
