Hi Paul,

Thanks for your reply. I did enable the Debug serial port back but
nothing seems to come out on the debug serial line. Instead I have a
dump in my ethernet debugger which is as below ....

As it can be seen very clearly from the above log, there is a definite
disconnect between the SysIntr values that I am providing in my
registry and the one which the system is seeing. The values are in HEX
as I can see.

My question is, in the registry, do I need to provide the HEX SysIntr
values or the decimal. I think the offset is IRQ + 10. Is this offset
HEX 10 or decimal 10 that I do not know now.

I hope you can help me with this issue.

Thanks in anticipation,

Best Regards,
