Even
after

been
successfully
read
into
memory,
certain errors can occur in
the
subsequent
initialization
procedure.
During
initialization
the
resident
operating system cannot access
the
error

processor
since
it
has
not
been
initialized.
Messages

fo~mat
to those generated
by the diskette controller are
displa~ed
to
indicate
such
errors.
They
differ from the diskette controller errors in
that the second character of the two-character message
is
a
non-numeric character.
The following errors can occur during
initialization,
but only after the resident operating
system
has been read into memory_

indicates that there was
insufficient
memory
to
accommodate
the resident portion of the operating
sy stem.
E!
The memory requirements described
in
section
1. 1
should be reviewed.
If
the
minimum
reqUirements
are
satisfied,
then
the existing memory
should be carefully examined for
bad
locations.
The
version
and
revision
or
MDOS
already loaded into
memor9
are
not
the
same as those on diskette.
This
error usually occurs as the result of
switching
diskettes
in
drive
zero
without following the
initialization
procedure· outlined
in
section 2.1..
The error can also occur
if
the
ID
sector has been damaged.
