Slower than expected, sorry for that. I was interrupted by a higher
I'm trying to find out where the 82077 registers are mapped, it seems
they are not at the beginning of IOASIC slot #11 (the floppy slot),
writing at this address does not work (i.e. no value stored),
(BTW, the floppy_enable bit is set in the SSR).
I'm surely missing something, since the ISDN driver and the ASC driver all
see the registers at the beginning of their respective slots...
I ran the floppy PROM tests and everything is OK. Is is possible to dump
the asm code of a PROM test?
