How do you access memory address $c100 directly using D3?
I could do it with D1 thus...
myselector:=allocselector(DSEG);
setselectorbase(myselector,$c1000);
setselctorlimit(myselector,$ffff);

I could then read/write as...

mydata:= mem[myselector:offset]

"...You cannot directly access physical memory in Win95/WinNT 32bit mode. You
                   will need a device driver that will access the memory for you and provide
                   the hook through the Windows API to gain acess. For an example of this,
                   check out http://www.bluewater.com..."
