Can Windows 2003 32-bit run on 64-Bit Processor . . .

Hello,

I know this is a stupid question but I do not know if the following is
possible.

Can Windows 2003 Standard (32-bit) run on an Intel P4 3.0 EM64T chip?
If so, are there any issues you can think of?

I have four brand new P4 3.0 EM64T Chips with compatible Intel Motherboards
and would like to use them
in a project I am gearing towards.

I have spent many hours surfing trying to obtain an answer but have not
found any that are concrete. The closest
I came to an answer was at...
http://www.windowsitpro.com/Windows/Article/ArticleID/44686/44686.html
" And because the x64 platform is compatible with today's 32-bit OSs
and software,
customers who purchase x64-based servers, workstations, or PCs today
will be able
to upgrade to 64-bit Windows versions in the future and still run all
their existing applications...."

Thank you for your time.

Hardware
Motherboard: D915GEVLK (supports chip below)
Chip : P4 3.0 630 EM64T (A40)

 

Don't worry, Windows Server 2003 x86 (32-Bit) runs just fine on Intel EM64T
Processors.

Yes, with no issues at all.

As far as I know, you can not upgrade from 32bit to 64bit, but you can reinstall.
You may want to install the 32bit version in a WINNT folder instead of Windows, then when you go 64bit, You can install it to the
default Windows folder and dual boot until you have it fully functional.

 

Yes. The 32-bit versions of Windows run on the Intel EM64T and the
AMD64 CPUs. They both have 32-bit modes as well as the 64-bit mode.

The only restrictions I have come across is with some of the PCI-Express
boards with nVidia chips state that Windows 95/98(SE)/ME will not run on
them. I have never seen a reason, though.

 

Do not "upgrade" from 32bit to 64bit. You WILL end up with problems.
Win 64bit uses a different folder for 32-bit programs, and the 32bit
support files are in a different folder, too!

Only a clean install of the 64bit Windows is recommended!

If you want to dual-boot, then install the 64bit in a separate partition
or drive after 32bit is installed.

This subject has been discussed many, many times over the past 2 years
and virtually everyone who did not heed the advice wound up with
multiple problems!

 

Good tip about the Win9x issue with the nVidia chips.

There is another reason for not running Win9x and that is the memory
limitation of 512mb (given that most users of these boards are likely to
want to run 1GB or more anyway). I am using Virtual Server 2005 R2 to get
around this.

 

Amen! Do NOT go there.

 

Separate partitions would be best.

I do't heart about different Windows version in the one partition!
