The

In
addition,
if the resident operating
s~stem
file does not
have a RIB in the proper physical sector;
the diskette
could
not
be
used for system initialization in drive zero.
Thusl
the message
MDOS.
SY
DOES NOT START AT
SECTOR $18
is
displayed
in
such cases.
Since
erro~s
in
the
directo~y
entries
are
not
Tatal
insofar
as
REPAIR is concerned (they can be if the diskette
is to be used for initialization or
to
run
any
pro~rams),
Phase 3
is
started after these checks have been completed.
22.4
Retrieval Information Block Check
Phase
3
of
REPAIR
checks
the
Retrieval Information
Blocks (RIBs) of all directory entries that have a valid
RIB
address.
If
a
RIB
address is invalid in a directory entry,
then the
RIB
cannot be found.
The RIBs are
checked
in
the
order
in
which
they are referenced in the directory.
If
a
RIB
secto~
cannot be read,
the
following
message
will
be
displayed:
**PROM I/O
ERROR-STATUS=31

The

an "Nil to the

If a

is entered, REPAIR
wi

attempt
to
rewrite
the
RIB.
If
the
error
is
cleared,
REPAIR will
continue.
If an error occurs during
the
rewriting
of
the
RIB,
or
if
an "N" was
ente~ed,
REPAIR cannot check the RIB
any further.
Thus, a message of the form
