If you don't have them, they are available as part of the latest include files, on the 'Native Developer's Upgrade' you can get from CBM (CATS) for about $20 or $25. If the GVP allows you to define a partition with a DEVS:Mountlist entry, you can probably make a mountlist to include cylinder 0 and then use something like Sectorama or DiskX to look at the RDB area. Sectorama won't be much good for making changes, since it seems to insist on having a valid checksum of the block in longword 5, but DiskX will likely be able to write any changes out. Good luck. -larry -- "Cavett Emptor - Let the talk show host beware!" - Evan Marcus +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

While doing some naughty experimenting with the mountlist in
the RDB section of my hard disk I corrupted it and was not
able to restore it. I have used GVP's installation program
with manual parameters before with no problems but this time
nothing I did would restore it. What I realized is that I
really didn't know what I was doing!
Does anyone have any kind of specs (official or otherwise)
on this autobooting standard that I think CBM and a few
controller manufacturers agreed on about a year and a half
ago?
I was left with default icons for the partitions which said
DH0:NDOS and DH1:NDOS which I guess stands for no dos.
They where not accessible through any normal means, even
by creating a manual mounlist in Devs:.
Let this also be a testimonial to the wonders of Disksalv.
It was the ONLY thing I could find that would read the data
on the disk. Since the second partition was a backup of the
first and they were both gone I had to spend a pleasant
Saturday afternoon feeding Disksalv 48 floppies. I was able
to completely reconstruct the disk with no complications.
Again, I anyone has information on the RDB specification
please contact me.
Thanks!
