I have a Symbios 53c770 chip attached to a PowerPC
processor in my Amiga.   The processor board has a PPC
604e chip.  The 604e runs in big endian mode (same as
a 68K chip).  I *believe* the 53c770 is running in big endian mode as well
but am not certain yet.   I have enabled the
MMIO of the SCSI driver since I am told the Amiga really 
doesn't know anything about IO_MAPPED, that that is a
concept more applicable to PC style hardware.  In any
event I have included the debugging output of the driver.
The driver stops when performing the cache test and 
dumps some SCSI SCRIPTS code.   Can anyone give me
some pointers on how to interpret and understand this
dumped information?  From what I read so far this 
information must be opcodes for the SCSI processor.
Is there a listing of these opcodes somewhere?  Thanks.

Fred
