Hallo Mikael,

This knowledge is not needed. What I meant was that the drive cannot know
with what it is exchanging data. You also can reason the other way around: a
normal C64 and C128 don't notice that 64HDD isn't a real 1541. Unfortunately
a speedloader will as 64HDD doesn't execute 6502-ML ie. it is a simulator,
not an emulator. But the C128 CP/M uses the original 8502- routines to
address drives ie. no reprogramming of the drive. So IMHO CP/M won't see at
all that the drive it is talking to a fake drive.
Another remark: a good source is the C128's own Z80-bootROM.
