2000 Protects the IO ports.  You need to write a kernel driver in order to
talk to the low level IO ports under Nt/2000.

Hello, 
I have a DJGPP-compiled hardware driver working fine under Win98/DOS.
I have tried to re-compile under Win2000 and appear to be unable to
write to the hardware registers.   This is a PCI Bus card, and we
get the Base Addresses from the hardware device manager, as we did
under Win98.  In general DJGPP appears to compile the code, except
for the inportb, inportw, outportw, and outportb commands.  

Thanks in advance for any help/advice.
