[9fans] Installation, While Not Hanging, Is Hung Up On Prepdisk

[Dan Todd <drowsyone@flashcom.net>]

I put the Plan9 partition at the very start of my primary slave disk as
a primary partition.  The installation created the partition OK, I guess
(no error messages).  However, it refuses to write its own suggested
subpartitions (9fat, fs, swap), always saying that it "cannot write to
/devdr".  I hope I have that right because I sure don't want to close
out here and go back just to get that message down perfectly.  After
seeing this a bunch of times, whenever I type "w", I quit, go back in to
Prepdisk from the prompt, type p to list the disaster, and find that all
three partitions are in there safe and sound, with no ' by them to show
that they have not been written in yet.  However, back out of prepdisk,
Plan9 will not let me go on to any other functions listed in the
Installation pages.  In fact, it does not include those functions coming
after prepdisk in its own online list.  I got the floppy image on July
29th.  I have not looked at plan9.ini.  Any suggestions for Joe User
here?  Thanks loads for trying.
