SYMPTOMS
If your computer normally reports two system processors while running Windows NT and one processor fails, your computer may stop responding. When you attempt to restart the server into Windows NT you may receive the following error message on a blue screen:
If your computer is a Compaq SystemPro compatible system, the following error message may be displayed:
CAUSE
This behavior occurs when the APIC tables are not available for use by the multiprocessor hardware abstraction layer (HAL).
The HAL looks for APIC tables enabled in the system firmware/BIOS. These tables are enabled only if both processors are installed and recognized by the system firmware/BIOS during power-on self test (POST).
RESOLUTION
Until the hardware or processor can be repaired or replaced, use the uniprocessor kernel and HAL files to get the system back into production. To do this, use the appropriate method.
NOTE: If your system has a service pack installed, you must use the Ntoskrnl.exe and Hal.dll files from the same service pack version as that of the computer you are attempting to repair.
If the Windows NT System Files are on a FAT Partition
- Start the computer using an MS-DOS disk.
- Copy the regular uniprocessor versions of the Ntoskrnl.exe and Hall.dll files from the Windows NT CD-ROM (or service pack source folder) to the %SystemRoot%\System32 folder, and rename the files to Ntkrnlsp.exe and Halsp.dll, respectively. For example, type the following commands:
- copy d:\i386\ntoskrnl.exe c:\winnt\system32\ntkrnlsp.exe
- copy d:\i386\hal.dll c:\winnt\system32\halsp.dll
Modify the Boot.ini file and make a new entry as follows:
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Server Version 4.00 [Uni-processor]" /kernel=ntkrnlsp.exe /hal=halsp.dll- Restart the server and select the new [Uni-Processor] option from the Boot menu. Choosing this option loads the uniprocessor files Ntkrnlsp.exe and Halsp.dll (instead of the normal multiprocessor files) so that you can restart the computer and log on.
After you fix the processor or hardware problem, restart using the normal Boot menu option. You should once again be up on multiprocessor support.
NOTE: If you want the [Uni-processor] boot entry to remain compatible after you install service packs in the future, you must manually update the Ntkrnlsp.exe and Halsp.dll files with the version included in the newer service pack.
If the Windows NT System Files Are on an NTFS Partition
Use the Emergency Repair Disk (ERD) to install the uniprocessor HAL and kernel files on the system using the steps outlined below. For further information, you can refer to the following article in the Microsoft Knowledge Base:
164471 Replacing System Files Using a Modified Emergency Repair Disk
Make a backup copy of the Setup.log file located on the ERD. Modify the original file by adding two entries in the [Files.WinNt] section as shown in the following example:
[Paths] TargetDirectory = "\WINNT" TargetDevice = "\Device\Harddisk0\partition1" SystemPartitionDirectory = "\" SystemPartition = "\Device\Harddisk0\partition1" [Signature] Version = "WinNt4.0" [Files.SystemPartition] ntldr = "ntldr","2a36b" NTDETECT.COM = "NTDETECT.COM","b69e" [Files.WinNt] \WINNT\system32\ntoskrnl.exe = "ntoskrnl.exe","99999","\","source disk","ntoskrnl.exe" \WINNT\system32\hal.dll = "hal.dll","99999","\","source disk","hal.dll"- Place the uniprocessor version of the Ntoskrnl.exe and Hal.dll files from the service pack or Windows NT installation CD-ROM on a separate disk.
- If you are repairing a Windows NT 4.0 system, replace the Setupdd.sys file from Windows NT 4.0 Service Pack 2 or later on Setup Disk 2, as described in the following article in the Microsoft Knowledge Base:
168015: Files Not Replaced When Running Emergency Repair on X86 Intel
- Boot from the three Setup disks. Click R to repair, and then click the Verify Windows NT system files option.
- After you replace the kernel and HAL files, press F3 to quit the repair process (do not let the repair process replace any other files).
- Restart the server. The uniprocessor kernel and HAL files should be loaded, and you should be able to log on.
- After you log on, create a Boot.ini entry to select a [Uni-processor] environment to ensure that you can log on to Windows NT easily in the event of another processor failure.
- Make a copy the uniprocessor versions of the Ntoskrnl.exe and Hal.dll files located in the %SystemRoot%\System32 folder, and rename them to Ntkrnlsp.exe and Halsp.dll, respectively. For example, type the following commands:
- copy c:\winnt\system32\ntoskrnl.exe c:\winnt\system32\ntkrnlsp.exe
- copy c:\winnt\system32\hal.dll c:\winnt\system32\halsp.dll
Modify the Boot.ini file and create a new entry as follows:
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Server Version 4.00 [Uni-processor]" /hal=halsp.dll /kernel=ntkrnlsp.exe- Restart the server and select the new {Uni-Processor] option from the Boot menu. Choosing this option loads the uniprocessor files Ntkrnlsp.exe and Halsp.dll (instead of the normal multiprocessor files) and then you can log on.
- After you fix the processor or hardware problem, copy the multiprocessor version of the Ntkrnlmp.exe and Halmps.dll files from the Windows NT installation CD-ROM (or service pack) to the %SystemRoot%\System32 folder, and then restart the computer. For example, type the following commands:
- copy d:\i386\ntkrnlmp.exe c:\winnt\system32\ntoskrnl.exe
- copy d:\i386\halmps.dll c:\winnt\system32\hal.dll
You should be up on multiprocessor support, but a Boot menu choice to use uniprocessor support is now available.
