READING FROM S6,D1
T00,S00 FOUND DOS 3.3 BOOTLOADER
USING DISK'S OWN RWTS
WRITING TO S6,D2

THE DISK WAS COPIED SUCCESSFULLY, BUT
PASSPORT DID NOT APPLY ANY PATCHES.

POSSIBLE REASONS:
- THE SOURCE DISK IS NOT COPY PROTECTED.
- THE TARGET DISK WORKS WITHOUT PATCHES.
- THE DISK USES AN UNKNOWN PROTECTION,
  AND PASSPORT CAN NOT HELP ANY FURTHER.

Despite the log, the disk is quite well
protected. Every other track has a non-
standard address prologue, and the RWTS
looks for a timing bit after the first
address epilogue byte. But it can also
read standard disks, so after Passport
converts the disk to a standard format,
no further patches are required.

Other disks have identical protection.

Quod erat liberandum.
