assembling with tasm

2007-11-17 JRH:
--------------------------------------------------------------------
Added a makefile

Changed package from .bin to .CO so we don't have to implement
proper interrupt handlers for now. This is temporary.

Added dependency on mtcpm/linux_tools for .CO conversion (need Perl)

Note: Start and HIMEM are now factored out of the code.
You need to supply them to tasm with the -d option... the makefile
does this for you, but you can still assemble from the command line:

tasm -85 -b -g3 -s -dStart=50000 -dHIMEM=60000 mtcpm.asm bios.bin
bin2co.pl bios.bin BIOS.CO 50000 50000

Should do the trick under Windows.

Note that some of what the makefile does is convert from MS-DOS
style line-endings. Linux version of tasm doesn't like them.
