Memory allocation question

I've read that XP will only allow any given application to use up to
two GB of memory. Is this true?

If it is true, is there a way I can configure so it will use more?

The reason for my question is that I want to work with really big
graphic files in PhotoShop, over two GB in size.

I've just built a computer with four GB of RAM.

Thanks.

Correct your boot.ini file:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /3GB /Userva=2900

Yes, 2G is the max amount of memory that can be allocated to a given
process. However, Photoshop et. al. have been dealing with larger files than
can be fitted in real/virtual for an extremely long time.

Don't worry about it. Just make sure that you do *not* play games with
virtual memory. In fact it would be best to set it to system managed.
