Short:        Update to OSSI EPROM project
Architecture: m68k-amigaos

This is a minor update to the prior release of otronic.lzh for
OSSI-OTRONIC-SCSI-controllers for A-500/1000.
Now the driver tests every SCSI-device before sending commands.
A typical situation is: Parall POWER-ON of a hard drive
and rebooting the AMIGA. Now the driver sends a START UNIT command
if the drive needs it for starting spinning up and then the
driver waits until the drive is ready to accept further commands.
If the drive's self test during spinning up fails the device driver checks
this condition correctly and releases the faulty devices. The driver
performs these steps for every SCSI id except 7. (The controller id)

Correct Supporting of Changeable Media like SyQuest drives 
still is a problem because this Low Cost Controller doesn't generate
interrupts during the command phases (The INT-lines aren't connected to the
ZORRO-bus), therefore it isn't possible to support RESELECT without 
CPU-intensive polling of the AM5380PC's control 
register for a RESELECT condition.
The RESELECT feature makes it possible that the controller becomes
a target.
