The doit shell file cd's to $H, which refers to the directory
that contains the hello world test. The console is a raw com port.
Certain test programs behave differently with different com port speeds.
To test the programs, it is required that you hook up a terminal
( or minicom or procomm it doesn't really matter ) to the comm port of
the target hardware. You must ensure that the baud rate, parity etc
is set properly. This is done on the target hardware within interns.s .
( Set your terminal emulator to match. ) Currently, the settings
are 9600,8,n,1 .
The format and layout of the file interns.s is taken from the
intel ApBuilder software, freely distributed by Intel. Some
easy macros ( SetExRegByte and SetExRegWord ) are basically lifted
from the Intel macros. Similarly for the names of the IO ports.
This "port" begain with the forceCPU bsp. Hence I am sure that
there is some real trash that is not appropriate. For example
the act of copying the Interrupt Descriptor tables and Global
descriptor tables "into our space". ( in start.s I think )
