PC
I/O
The
core
chipsets
have
standard
interfaces
for
the
following
devices:
v
PS/2
keyboard
and
mouse
v
Parallel
printer
v
Two
RS-232
ports
Models
741,
742,
781
and
782
contain
two
additional
RS-232
channels.
Drivers
are
required
to
enable
these
ports
(for
all
operating
systems)
and
are
available
through
the
support
page
on
the
Web
(www.ibm.com/solutions/retail/store
and
then
select
support.)
.
Because
these
ports
are
PCI
devices
and
fully
Plug
and
Play
compliant,
applications
must
use
OS
and
BIOS
calls
to
discover
their
locations
in
the
system’s
I/O
map.
Also,
these
applications
must
be
able
to
share
the
PCI
interrupt
structure,
if
interrupt
support
is
required.

Note:
USB
1.1
devices
can
be
used
with
USB
2.0
ports
(at
USB
1.1
speeds),
and
USB

devices
will
work
on
USB
1.1
ports
(at

System
memory
All
system
boards
have
two
memory
sockets.
The
factory-installed
base
memory
occupies
one
of
the
sockets.
An
empty
socket
depends
upon
the
initial
order
for
base
memory.
Use
only
memory
provided
by
IBM
Retail.
Note
that
not
all
third-party
memory
modules
work
with
every
product.
IBM
performs
extensive
life
and
reliability
testing
to
insure
that
the
memory
offered
by
IBM
will
operate
correctly
over
all
voltage
and
temperature
ranges.
Optional
USB
DASD
External
USB
drives,
such
as
HDD/ZIP,
diskette
or
memory
key,
operate
with
the
product;
IBM
provides
USB
boot
support.
You
have
to
test
any
specific
USB
device
not
offered
by
IBM
Retail
prior
to
use.
This
requirement
is
especially
necessary
due
to
the
implementation
differences
between
drive
suppliers.
USB
support
The
SurePOS
Models
721/741/781
and
722/742/782
contain
two
different
USB
subsystems.
The
base
subsystem
is
implemented
on
the
main
processor
board
and
uses
the
core
USB
support
provided
by
the
motherboard
chipset.
Model
721
supports
the
USB
1.1
standard;
Models
741,
742,
781
and
782
support
the
USB
2.0
standard.
All
motherboard
USB
controllers
are
Universal
Host
Controller
Interface
(UHCI)
compliant.
Models
7x1
The
POS
USB
PC
ports
are
all
driven
from
the
POS
riser
card
and
comply
with
the
USB
1.1
standard.
These
controllers
are
all
OHCI
compliant
(except
those
machines
containing
the
front-powered
POS
USB
2.0
port).
