These values only seem to apply to the IDE device.
I'm also really curious what's going on with these values. We should probably figure out what they're for before we go hacking them in. Also, please make sure an X86 kernel still boots with this change. I remember getting the IDE controller to work was a little finicky at least partially because of its legacy fixed IO port locations, and it might break even though other ISAs are ok. - Gabe ----------------------------------------------------------- This is an automatically generated e-mail.
