2.3 PCI Device Interrupt Map
The
PCI
bus
‐
based
external
devices
include
the
Universe
IID
bridge,
PMC
site,
Ethernet
controller,
FPGA
and
the
GE
connector.
The
default
BIOS
maps
these
external
devices
to
the
PCI
Interrupt
Request
(PIRQx)
lines
of
the
6300ESB
I/O
controller
Hub.
This
mapping
is
defined
in
*The
Device
ID
for
the
Intel
82546EB
is
1010H.
The
Device
ID
for
the
Intel
82546GB
is
1079H.
2.4 Integrated Peripherals
The
VMIVME
‐
7807/VME
‐
7807RC
incorporate
an
SMSC
Super
I/O
(SIO)
chip.
The
SIO
provides
the
VMIVME
‐
7807/VME
‐
7807RC
with
two
16550
UART
‐
compatible
serial
ports,
keyboard
and
mouse
ports.
The
keyboard
and
mouse
ports
are
available
via
the
front
panel
using
a
standard
PS/2
type
connector.
COM1
is
accessed
via
the
front
panel.
COM2
is
routed
to
the
VME
P2
connector.
COM
ports
3
and
4
are
also
provided
by
the
6300ESB
I/O
Controller
Hub
and
are
routed
to
the
VME
P2
connector.
The
parallel
IDE
interface
is
provided
by
the
Intel
6300ESB
I/O
Controller
Hub.
The
IDE
interface
supports
two
channels:
primary
and
secondary.
The
secondary
channel
is
routed
onboard
to
the
optional
CompactFlash
socket.
The
primary
channel
is
routed
out
of
the
VME
P2
backplane
connector
to
an
RTM
which
terminates
into
a
standard
40
‐
pin
header.
This
channel
can
support
a
master
and
slave
drive.
The
IDE
interface
on
the
VMIVME
‐
7807/VME
‐
7807RC
supports
Ultra
ATA/33,
Ultra
ATA/66
and
Ultra
ATA/100
drives
and
automatically
determines
the
proper
operating
mode
based
on
the
type
of
drive
used.
In
order
to
properly
function
in
the
Ultra
ATA/100
mode,
a
special
80
conductor
cable
must
be
used
instead
of
the
standard
40
conductor
cable.
This
cable
is
typically
available
from
the
Ultra
ATA/100
drive
manufacturer.
A
Serial
ATA
Drive
Interface
is
also
provided
by
the
6300ESB
I/O
Controller
Hub.
The
Serial
ATA
port
can
be
used
alone
or
in
limited
conjunction
with
the
parallel
IDE
interface.
NOTE
Selection of drive type (parallel or serial), along with detailed IDE/ATA selections is available in the
CMOS Advanced BIOS Setup Menu.
