I don't think you've said if you disabled your mobo chipset's integrated
IDE controller or not, the ones legacied to 0x1f0 and 0x170. If you
disabled BOTH those ports or you have the 'boot offboard controllers
first' option in your kernel, then your offboard controller should be
mapped to ide0 and ide1, IMO. It makes logical sense to me since IDE ports
seem to come in pairs these days, excepting ISA interfaces. ;)
