I'am currently investigating that code path, Dan.
We have also come to the same conclusion as u.
But believe me, I had tried with all possible
Switch settings, S3,S4,S5,S6. :-( Its tantalising !
This means that all ISA interrupts are not
being routed properly. One more, I haven't
initialized the WinBond, coz reset values seem
meaninful. Could that be the reason for
this ?

Any suggestion from experienced people is welcome.
Is there any other switch, other than the S3,S4,S5,S6
I need to worry about.
