Perhaps rather for the better informed user.
There is a boot-time switch on some versions of Windows
/3gb
It isn't completely clear which OS the flag is available for. The help files
suggest Windows NT and later servers, and Windows XP Pro.
It is /3GB, not /3gb.

By default the OS kernel grabs 2gb of RAM, leaving 2gb for applications.
According to MS documentation, adding the switch reduces the OS to 1gb and
leaves 3gb for applications.
You sound rather confused. This refers to the 32-bit address space of a
program, not RAM, and it is `reserves' not `grabs', those being separate
operation in the wonderful world of Windows.
Is the 2gb limit you report innate to S+ or is it this limit?
It's innate to applications which are not marked in the PE header as
large-address-space-aware, and Splus.exe is not in my copy (S-PLUS 6.2): I
just checked it with the MS tools.
