A simple DOS386 question.

I've done research on the DOS extended environments and it appears that most
programs written in C would "port" fairly quickly.

However, one nasty thought remains in my head.  What if you were going to 
port a program that contained 10% 8086 assembler?   Do the 386 compiler's
such as watcom's support anything for assembler.

Would 8086 assembler have to be translated to 386 specific assembler?

Given the giant speed increase of running under 386 protected mode, would it
be worthwhile to try to convert the assembler to C code and port that instead.

What if the aforementioned assembler programs were device drivers; does that
make things significantly worse?


I'll summarize significant postback's

Thank's
