[Freedos-user] How to set CWSDPMI for 4GB of RAM?

[Roberto Waldteufel]

Hello everyone,
 
I have a computer with 4GB of RAM and would like to 
write 32-bit applications (using the FreeBasic 32-bit compiler for DOS) that use 
as much as possible of this memory. I find the executables generated 
will run well enough under FreeDos, but they can only see 2 GB of RAM. I am 
using CWSDPMI version 5b as my DPMI server. Please can anybody tell me how (or 
if ?) I can configure CWSDPMI to access all of my physical RAM? If this is not 
possible, can anyone suggest an alternative DPMI server that supports 4 GB 
?
 
Best wishes,
 
Roberto Waldteufel

Roberto,
Are you using a XMS driver (probably), and which one 
(HIMEM.SYS/HIMEM.EXE/FDXMS.SYS/FDXXMS.SYS) exactly?
can you run MEM /C /P from the commandline and paste the output into 
your next email? That way you can see how much RAM the XMS driver gives 
access to.
I don't know if XMS driver is required for CWSDPMI though.

XMS driver isn't required. I don't know the answer, but you should
also post your question in the DJGPP newsgroup!
Bye, Flo
