Onboard Resource Settings
External SMI
The EXTSMI (External System Management Interface) connector,
JP25, is used by some plug-in cards. Certain applications associated
with these plug-in cards use the interface for hardware control and
queries.
Chassis Intrusion Alarm Connector
The J8 connector is an intrusion alarm, that can be connected to the
system chassis. When active (J8 is connected to the chassis), this
alarm will alert the system administrator anytime someone opens the
system’s case.
Audio Connectors
(S1836DLU only)
There are three 4-pin connectors onboard which are used for various
peripherals’ audio signals. The digital signal that comes in through these
connectors is directed through the Creative Labs Vibra 16XV sound
chip, and the digital signal is turned into an audio signal which goes out
through the speaker. JP18 is for modem input/output, JP19 is for
Panasonic CD audio, and JP20 is for Mitsumi CD audio.
Windows 95 Users:
You may encounter problems with some of the devices in the Intel
82371EB chipset. Neither the PCI Bridge
nor the PCI Universal Serial Bus device
IDs for this chipset (also called PIIX4e) are
recognized by Windows 95. This is a soft-
ware problem, not a hardware problem, and
can be easily remedied by either upgrading
to Windows 98 or downloading the 82371EB
patch found at http://www.tyan.com/html/
drivers.html or at ftp://download.intel.com/
design/pcisets/busmastr/setupex.exe. Note
that USB requires Windows 95 OSR 2.1 or
battery
