Can this > be fixed somehow? There are only two ways currently to find fd0 on ISA systems: ACPI _FDE probing and hints. The acpi probe automatically falls back to the hints system if _FDE fails so you should leave the hint.fd.0 lines in but comment out hint.fdc lines (as you've done). I think the problem is that ISA is creating a duplicate fdc0 device via the hints. I'm not sure the best way to solve this. -- Nate
