Hi,
the attached patch adds code to checksum the pci extension rom and stop if the stored and calculated checksum differ.
Is this checksum reliably correct? I am hesitating to add new restrictions that might break otherwise working cards.
You are right, attached is a correct method. There is no fixed checksum byte, instead the whole should sum to zero.
Any comments on this?
I like it. I'd give you an Ack, but I have no hardware to test with.
Stefan? Ron?
Worst case would be that buggy extension ROMs break with a really loud warning, so anybody with such ROMs will see it prominently in the logs.
Alex: Is there an easy way to check extension ROMs in the current machine for correct signatures? Maybe standalone utility or such stuff.
