Hi, I know how to change SW interrupt vector address, but my problem is that it will not work if I don't change it HW too.
Is the AT89C51ED2. This micro doesn't say anything about changing the HW vector addresses.
Does someone know how to do that?
Regards,
Piero

You can't - because it is hardware!
So, one of the ways to make it work is to store in the interrupt address a jump to the real interrupt address?
I'm trying that and it seems to work fine.
Thanks,

That is the only way to make it work!

Unless you're using a variant with some special interrupt-redirecting hardware - which is not the case here!
Thank you very much. You were very helpfull!
Best Regards,
