64bit Vista & 32bit XP
Ron O'Brien
would speed up HD digital video editing, but my software application will
not run under Vista, so I'm thinking use Virtual PC.
The problem, I only have 32bit XP pro, but if That is installed as a virtual
set-up on the 64bit Vista Host, will it then be able to take advantage of
the 8gig of RAM or will it still max out at just under 4gig?

The key to this, as with 99% of Virtual PC questions is to consider what
would happen on a physical machine. As far as software (both OS and
applications) is concerned, there is no difference between a physical
machine and a virtual machine - in fact, the vast majority of software has
not the slightest idea that it's running on a virtual machine as opposed to
a physical machine.
So...
If you had a physical machine with 8GB RAM and installed 32-bit Windows XP
on it, would it be able to see all of the RAM? No, it would see just under
4GB of it, depending on the motherboard.
Similarly, if you created a virtual machine and assigned it more than 4GB of
your host's 8GB RAM, would 32-bit Windows XP be able to see all of it? No it
wouldn't, as above.
This is not a limitation or problem with Virtual PC - it is simply that 4GB
is the maximum amount of RAM which a 32-bit operating system can address.

Even if you hade access to XP-ProX64 it would not help since VPC2007
guests are 32 bit PC:s and so can only install 32 bit Operating
systems. So your 8Gb memory will not be usable for a guest, only about
3 Gb.
There is another problem too:
Since you talk about video editing I suspect that you will not find
the emulated video card available in a virtual machine useful for your
purposes. It is a Trio 64 card with only limited amounts of memory
(4-8 Mb if my memory serves me right) and it cannot handle DirectX 9
or higher...

Thanks for your input....I thought it was too good to be true!!! nice idea
though

FWIW, VMWare supports 64-bit guests "right of the box", as some people say.
So does / will Hyper-V...
However, that still won't allow a 32-bit OS to address more than 4GB RAM...

The maximum you can allocate to a VPC guest is 3.712 GB. It is set in VPC
itself.

Would you consider getting hold of a copy a XP x64 and multi-booting your machine?
If you want to multi-boot, I highly recommend BootIt NG (BING) from
terabyteunlimited.com.

Looks like that's my only option, though I must consider how much the 64bit
XP is going to cost me - shame they didn't do 32 & 64 bit on the same disk
like they have with Vista!

Where did you see both 32 and 64 bit Vista on the same disk? Most retail
versions are 32 bit only. Ultimate has 32 and 64 bit, but on two disks in
one container.

FWIW, most (it not all) MSDN / TechNet OS DVDs have both 32-bit and 64-bit
versions on the same disk...

That's certainly true.

But then they cannot be bootable DVD:s, can they?
Which system should they boot up to?

Why not?

Whichever system you choose in the boot manager...
One of the XP DVDs has, IIRC, eight different OS on it...

I have been reading the threads here to decide on my best plan for a new PC.
It sounds like I have the greatest flexibilty installing Vista Enterprise 64
as the primary OS, and then virtual PCs for the different OS's I need to
support. However, one of my apps uses OpenGL with (very simple) 3-D
rendering. What you wrote below implies that the 3-D rendering will not work
inside a virtual PC, even though the openGL can run now with relatively old
and bare-bones video cards. Do I understand correctly?
Thanks,
Richard U.

You can use 3D in a VM. There is no 3D hardware acceleration in a VM.
