For copy protected programs (like print shop), the 1571 drive must be in 1541
mode!  To ensure this, do not (*do not*) power up the 128 and enter GO 64 to
get it into 64 mode.  Instead, power it up (or push the reset button) while
holding down the C= (commodore logo) key.  Keep holding the key until the blue
C64 screen appears.  This will keep the 128 from sending fast serial commands
to the drive and the drive will stay in 1541 mode.  Using the GO 64 results
in the drive already having switched to the 1571 mode due to the autoboot
attempt during power on or reset.  Much copy protection relies on the drive
RAM being set up exactly like a 1541.
Sincerely,
Frank Prindle
