Yes this is the same machine...same CMOS (bios) settings.
I am running an Athalon 1200 (not exceptionally fast). But to make
things interesting I am running this with Gentoo linux (custom built for
the machine).
It works for most things quite well.
It is acting like a timing problem... I really need to get a logic
analyzer to determine what is going on. It is a little hard to tell
without seeing where the differences are.
Under 98.. both IAR and GNU tools seem to work. Under linux it is a bit
flaky ... I am thinking of porting to a Mandrake machine that is around
to validate the it works well. These are only 1GHz machines.
I have compiled the ppdev and parport into the kernel (not modules) with
no real effect. that is ... still flakey.
I have not tried to take it any further. I may need to sort out a logic
analyzer and how to get the HIL lib into debugging mode. That will be
another day i am sure.
Regards,
Jim
