I am running a Pentium III with 128 megs of memory.

I ran go32-v2 and it reports :
DPMI memory available 129471kb
DPMI swap space 0kb

my config.sys file has the following entries:

devicehigh=c:\dos\emm386.exe noems novcpi
dos umb.high
devicehigh=c:\dos\ansy.sys
devicehigh=c:\aoatapi.sys /d:mscd000
loadhigh c:\dos\smartdrv.exe c+ d+ f+ 8192
buffers=15,0
files=40
lastdrive=z
fcbs=40,0


autoexec.bat contains

set path=c:\djgpp\bin; c:\dos
set djgpp=c:\djgpp\djgpp.env


It took gcc hello.c -o hello.exe         55 seconds to compile and link.
This was a one line program. What am I missing ? (or is this normal )

Should I install himem and set up a ram disk for work files for gcc ? (how)

Some General questions about DPMI server:

I have been writng embedded applications under turbo c under dos where I
handle the hardware interrupts from the keyboard, mouse serial ports and
timer.

One application that I would like to port has the following interrupts
occuring continuously,

I programmed the timer to interrupt 42,613 times per second. (in the isr I
do direct i/o to the parrallel port)
I am using wattcp to exchange tcp/ip packets with an  I/O controller 100
times/second.
I get 100 interrups/second from the dma engine that handles the AC97 link.
serial data is being streamed out to a com port at 125kb.

All of the above interuppts are being handled by my app.

Am I barking up the wrong tree trying to port to DJGPP ?

What is the difference between CWSDPR0 and CWSDPMI ?

Thank you in advance for your response.

Daniel Galasso.
