The
QUARK
Operating
System
An
initial
operating system
is
ready to
be
loaded
from
the Distribution Diskettes. This
operating system
is
configured
by
Megatel
to operate
lJ'lder
a "worst-case" system configuration-
that
is,
a
hardware
configuration consisting of only
one
single-sided low-performance floppy
disk
drive,
and
either
a
keyboard/CRT
console device
or
a
RS-232C
terminal.
After the
initial
operating system
has
been
successfully loaded
from
one
of the
Distribution Diskettes, the actual parameters of the
"target"
system
may
be
entered using the
submit procedure
QINSTALL.
The
QINSTALL
submit
file
contains menu-driven
CP/M
customization
programs
which
have
been
written
by
Megatel
specifically
for use with the
QUARK.
QINSTALL
allows the
QUARK
user
to
change
the basic I/O configuration of the
CP/M
operating system
without requiring a thorough understanding of the operation of the
BIOS
or of the
programming
of the l80B.
With
QINSTALL
the user
may
modify
the parameters in the operating system for
optimum
performance with his
final
system hardware.
As
well, various I/O ports not
needed
for
functions
assumed
by
the Distribution operating system
may
be
freed for other uses. Finally,
other system parameters, such
as
the
baud
rates
to
be
initialized
when
the operating system
is
loaded,
can
be
specified through
QINSTALL.
The
CP/M
operating system supplied
on
the Distribution Diskettes
is
configured
to
support
one
physical drive
(i.e.
a single floppy disk drive
unit)
and
four logical
drives,
named
A:,
B:,
C:
and
D:. Before
installation
of the system, the disk formats of
all
logical drives A:,
B:,
C:,
and
D:
will
be
compatible with the "Megatel format"
used
on
the Distribution Diskettes.
By
ruming the
installation
procedure
QINSTALL,
the user
can
customize
up
to
four physical
drives
and
four logical drives.
Because
different
logical drives
can
access the
same
physical drive, the user
must
ensure
that
the correct
diskette
is
inserted into the correct disk drive.
