Hi,
I noticed that ATA packet writing is supported by the IDE emulation, provided
that an IDE device is marked as a CD-ROM. Doing this non-programmatically
does not seem to be supported, even though the emulation appears to be
functional. Any reason why this is not configurable? Or is it and I missed
something?
There are two kinds of emulations, one with packet writing (device name is
QEMU CD-ROM), and another one. I'm not sure about that other one (device
name is Hatari CD-ROM), it appears to be a non-packet (pre-packet) protocol?
One other thing I'm also not sure of: I have the impression that the Hatari
byteswap features collides with data transferred via the packet interface.
Data might be swapped when they should not be?
Best regards
Uwe
