Upgrading to Multiple Processors Help?

[tkawika]

I am trying to upgrade a HP Netserver from one processor to two. I am running NT4Sp6a. I have tried, unsuccessefully,uptomp.exe twice. Once using a "MPS Multiprocessor PC" and "Standard PC" hal. But both times it came up with the same error. "....Corrupted or file missing...NTFS.SYS.." error on the reboot. The uptomp.exe procedures runs fine and when it restarts, I get the error above. Any comments would be much appreciated.

Is your BIOS set to allow both processors? Do you need a BIOS patch?

Sounds like when you try to use 2 procs, something like the disk controller stops working so you can't find the OS?

Are you booting to original OS or reinstalling?

I'm not too familiar with HP servers. HP may have a utility to convert single processor HAL to multiprocessor HAL. (I know Compaq Software has this ability.)

Try these intructions....

SUMMARY
=======

This article describes how to change Windows NT from single processor support to
multiprocessor support or from multiprocessor support to single processor
support.

MORE INFORMATION
================

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.

TITLE : Upgrading from Uni- to Multi-Processor Requires Service Pack

ARTICLE-ID: Q142660
TITLE : Upgrade from Uni- to Multiprocessor (Uptomp.exe)and Win32k.sys

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.

Actually I found a much better way than the uptomp.exe. I have spoke to a lot of different people and it seems they have run into the same issues that I did. Here is a link to the way I upgraded. It worked for me.

Just follow the instructions and it should work.

Thanks for the responses

That's a useful link TDK - how about an FAQ on that too? Or even making the instructions into an FAQ to people don't even have to go elsewhere?
