README for DOS
==============

The DOS port uses djgpp. If you want to get djgpp, or find out more, see
http://www.delorie.com/djgpp/v2faq/.

In the FAQ above are included instructions on how to cross-compile for
DOS using the djgpp libraries etc, which is how the executables in the
binary distribution were made.

If you want to make a real mode DOS program, see README.borland.

Binary won't run
----------------
Djgpp executables require a DPMI server to be running, this means
running in a DOS box under windows for example. A free DPMI server
is available from any of the sources of djgpp, the file you want
has a name such as v2misc/csdpmi1b.zip. See the FAQ for details.

Examining devices under Win95
-----------------------------
To find the readport address under win95, go to
My Computer -> Properties -> Device Manager -> System devices ->
IO read data port for ISA Plug & Play enumerator -> Properties ->
Resources.

This will give an address range, for example 0270-0273. The address
to use is the last one, ie 0x273.

To get the devices' resource data, use

pnpdump 0x273

where 0x273 is the readport address as determined above.

Then follow the example in the README to see how to generate a
script for isapnp to dump the existing values, or else just
edit the pnpdump output with reference to the device resource
values found in the Device Manager, device, properties, resources.

Transfer the resulting script to your Linux filesystem, and
configure your devices as normal (see INSTALL).

Using isapnp.exe with loadlin
-----------------------------
If you boot Linux from DOS using loadlin, you can also run the DOS
version of isapnp before booting Linux. This would allow you to use
normal compiled in drivers.
