This seems to be a Good News (tm).
So if at boot we check writablity of bit 2 and 3 we can know if this mechanism is implemented or not ?
We can do the test at trap_init() level. So we know how to (or not to) deal with NMIs. Just another thing. Can we rely on the bit 7 of the port 0x70 ?
Ciao, Riccardo.
