[vortex-bug] device driver for 3c905C

[vara prasad Ajjampudi]

Hi,

I am using microsoft c compiler. The function is outl() not iopd() (sorry 
for the typo). This does the 32 bit i/O operation.

Now as I am porting to real mode (to be pricise to work on DOS), I cannot 
use 32 bit operation.

So I would like to know the solution.

Thanks
