 The error is due to the mode of the parallel port.
 
 ppc driver detects NIBBLE (also called compatible) but the ZIP driver
 thinks the parallel port is in EPP mode. The ZIP protocol is
 completly different from one to another.
 
 So I guess that NIBBLE is right and EPP false.
 
 The problem comes certainly from one of the functions in the ppbus
 framework that returns the available modes of the parallel port to
 the zip driver.
 
 Either the ppc didn't initialize the info. correctly or the ppbus
 functions interpret it incorrectly.
