Help please

Dear helper,


I have  some questions regarding programming in C and assembly
languages. I am actually using C and
assembly for writing a program to display a specific information on the
LCD module.
1.the software I am actually using to write the programs I think was
designed to work with CPU486, but my computer is a pentium.What i would
like to know is there any problem for executing programs under these
conditions.

2.I have already wrote some program but during the execution there is
some link error and cannot identify their cause. 

3. during the installation of the C software the speed of my computer
has considerably decreased. I have checked autoexec.batand config.sys I
found that these files have been changed and particularly I found a
descriptive line in this files which is related toCPU486 (i guessed that
from the file name).since i have the  system back up I immediately
restored these two files. actually thereis no problem with my computer.
however the execution of programs give some link errors and also some
instruction error (outportb unresolved?, delay unresolved?) the outportb
function will send the data to the LCD controller and delay is used
tosynchronize the output.

4.is it possible to use visual C++ instead of microsoft C++, and borland
C++ and what is the difference between them.

5.is there any special words or instruction library available for
control and how to get them.
i hope you won't feel boring with my questions. i will appreciate a lot
to receive your answer as soon as possible. if you have any
more information you think they could be useful for me please send it to
me.


Thank you so much,
