Update of /cvsroot/src/sys/arch/hp300/dev
In directory netbsd1:/var/slash-tmp/cvs-serv10048

Modified Files:
        sd.c rd.c 
Log Message:
Bring some sanity into my frazzled existence:
- Always ensure that RAW_PART ("c") can be opened.
- Disallow unused or non-existent partitions from being opened.
- Don't do bounds checking or partition translation on RAW_PART.
This is consistent with other disk drivers in the NetBSD source tree,
and fixes a condition where the user could not fix a corrupted disklabel
due to a bogus offset for partition "c".
