Detect 3GB switch programmatically

[scorpneo]

Is there some way to (programatically) find out when the OS is booted
in the /3GB mode? The 32-bit version of my application sets a hard
limit of 1700 MB after which it does not try to allocate any more
memory. I'd like to switch this to 2700 MB when the /3GB switch is
available. The best I can come up with till now is to read the
boot.ini file, but I am wondering if there is anything clever out
there, that I can do.

Thanks,
Sashank.

I don't know. You would have a better chance of getting an answer if
you posted this someplace where programmers hang out.
microsoft.public.win32.programmer.kernel might be a good bet.
