Update of /a/cvsroot/src/sys/arch/mac68k/dev
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv216

Modified Files:
	ncr_sbc.c 
Log Message:
- Remove several hacks that didn't do much but waste cycles.
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.

The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.
