For what it's worth, I don't think it's SCSI termination that causes 
that error.  08:04 is another notation for sda4.  08 is the major 
device number for sda, 04 is the minor device number for partition 4. 
Actually, it's a little more complicated than that, but it suffices 
to say that 08:04 is the device number corresponding to sda4.

 From the errors, it looks as though the kernel's HFS filesystem 
driver is trying to read block 7289321 from sda4, even though that 
partition has just 20480 blocks.  20480 blocks equals 20MB if they're 
1KB blocks, which is a likely block size for a 20MB HFS file system, 
so at least that much makes sense.

What boot loader are you trying to use?  It looks like either it or 
something in the kernel is a bit confused about what to expect on 
partition sda4.
