Karl, Change the AuxType of the AppleDisk5.25 driver to $0103 and it will only see one drive. (use $0203 for two drives, etc) Works great :) -- -Harold Hislop Hardware Coordinator, Apple II RoundTable, GEnie 14Mhz/32k TWGS, 1Mb Rev-C RamFast, Prototype ROM_03 in tower (Heritage Mac hardware also spoken (great IIgs peripheral ;))
