Before you start, make sure that you have a complete, working backup of
the system files and the registry, and that you have a current Emergency
Repair Disk (ERD). To create an updated ERD, run Rdisk.exe from a
command prompt, and then select Update Repair Info.
To add support in Windows NT for an additional processor,
follow these steps:
NOTE: Some Compaq computers require a different HAL -- Halsp.dll.
Refer to the latest Compaq Software Support Disk SSD for details.
1. Install Windows NT to a separate folder on your hard disk, and then
restart your computer to the new installation of Windows NT.
2. In the %SystemRoot%\system32 folder of your original Windows NT
installation, rename the following files to alternate names:
Ntoskrnl.exe
Hal.dll
Kernel32.dll
Ntdll.dll
Winsrv.dll
Win32k.sys (additional file in Windows NT 4.0 only)
3. Determine which multiprocessor HAL your computer requires using the
following list:
Halast.dll = "AST Manhattan SMP"
Halsp.dll = "Compaq SystemPro Multiprocessor or 100%
Compatible"
Halcbus.dll = "Corollary C-bus Architecture"
Halmca.dll = "IBM PS/2 or other Micro Channel-based PC"
halmpsm.dll = "Micro Channel Multi Processor PC"
Halapic.dll = "MPS Uniprocessor PC"
Halmps.dll = "MPS Multiprocessor PC"
Halncr.dll = "NCR System 3000 Model 3360/3450/3550"
Haloli.dll = "Olivetti LSX5030/40"
Hal.dll = "Standard PC" (single processor HAL)
Hal486c.dll = "Standard PC with C-Step i486"
Halwyse7.dll = "Wyse Series 7000i Model 740MP/760MP"
4. Copy the Ntkrnlmp.exe file and the appropriate HAL file from the
Windows NT CD-ROM or installed service pack to the
%SystemRoot%\system32 folder of your original Windows NT
installation,
and then rename them to Ntoskrnl.exe and Hal.dll, respectively.
5. Copy the Ntdll.dll file from the original Windows NT CD-ROM or
installed service pack to the %SystemRoot%\system32 folder of your
original Windows NT installation.
6. From a command prompt, expand the Kernel32.dll and Winsrv.dll files
from the Windows NT CD-ROM or installed service pack to the
%SystemRoot%\system32 folder of your original Windows NT
installation. For example, type the following commands:
expand kernel32.dl_ %systemroot%\system32\kernel32.dll
expand winsrv.dl_ %systemroot%\system32\winsrv.dll
NOTE: To properly expand files from the Windows NT CD-ROM, you must
use the Expand.exe utility included with Windows NT. The Windows NT
Expand.exe utility can only be run from a command prompt in a 32-bit
environment such as Microsoft Windows 95 or Windows NT.
NOTE: In Windows NT 4.0, the Win32k.sys file is also required. Expand it
from the original Windows NT CD-ROM or the installed service pack.
7. Restart your computer.
8. When the Windows NT kernel loads, ensure that it displays
"Multiprocessor kernel" during startup.
Support for the second processor is now installed and is ready for use.
To return to single processor support, restore the old files to the
original names in the %System Root%\System32 folder, and then
restart the computer.
NOTE: The files located on the Window NT CD-ROM and in the
service packs are multiprocessor aware. To return to single processor,
you must install Windows NT on a single processor computer,
install any applicable service
packs, and then copy the associated files from that computer to the
computer you want to return to single processor. You should also update
the Setup.log file in the $SystemRoot%\Repair folder to reflect the
correct state of your computer in order for future service packs and the
repair process to function properly. To update the setup.log file run
rdisk and choose the update option on the first screen.
NOTE: When you change to or from single or multiple processors,
if you are using Proxy 2.0 server on the same computer, you also
need to replace the
Ipfltdrv.sys driver as well (%SystemRoot%\system32\drivers).
The single-processor version is 36 KB in size and is located
on the Proxy 2.0 CD-ROM in the Msproxy\I386\Routing\Up folder.
The multiple-processor version is
34 KB in size and is located on the Proxy 2.0 CD-ROM in the
Msproxy\I386\Routing folder.
