I've installed the NetBSD in a 500MB AU/X partition of my  LC II .
When I was installing files with NetBSD/mac68k install Utility most of 
them ,in the end, gave errors like this :
     Error on SCSIRead (), #5
     Error on SCSIWrite (), #5
     Error on SCSIRead (), #5    
     Error on SCSIRead (), #5
     Error on SCSIWrite (), #5
     Error on SCSIRead (), #5

pos = 0, i = 11, fs = /
alloccgblk:can't find blk in cyl

...this in all of them (distributed with NetBSD) except in the one called 
"netbsd121" (900k uncompressed).Could it be cause it's small??? But 
otherwise "etc121" is 350k uncompressed and gave the same error too :((

     When I was logging the bootlog gave me this...

  Bye-bye...
        So I sez to him...  The real way
        that it should be done is to...

     
     ...and then appeared me the following...

... and then it stoped and I'm forced to reboot the machine cause it 
simply freezes...

I hope someone can help me ... I'm kind new at this...sorry if my English 
is not correct but I'm not a native -speaker...
