This Technical Note formerly described how ProDOS 8 searches for devices and how it deals with devices which are not Disk II drives.


This Note formerly described how ProDOS 8 searches for devices and how it deals with devices which are not Disk II drives; this information is now contained in section 6.3 of the ProDOS 8 Technical Reference Manual.

Note: The information on slot mapping on page 113 of the manual and on page 2 of the former edition of this Technical Note is incorrect. ProDOS itself will mirror SmartPort devices from slot 5 into slot 2 under certain conditions. Devices should not be mirrored into slots other than slot 2. For more information, see ProDOS 8 Technical Note #20, Mirrored Devices and SmartPort.
