Chassis Intrusion Alarm Connector
The J7 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J7 is closed), this alarm will alert the system administra-
tor anytime someone opens the system’s case.
Ensoniq Audio Connectors (S1846SLA only)
There are four black 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 Ensoniq 1371 PCI sound chip, and the
digital signal is turned into an audio signal which goes out through the
speaker. The TDA connector (J10) is for modem audio; the MPEG connector
(J9) is for DVD and TV cards; the VIDEO connector is (J11); the CD connector
(J13) is for CD-ROMs.
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 above;
please contact Microsoft for the USB update.
CMOS RTC
The 440BX AGPset includes a Real Time
Clock (RTC) circuit, which provides the date
and time for the system. If the external
battery for the RTC is low, it will prevent
your system from POSTing, and you will
not get a display.. If your battery is running
low ,you will need to replace it with a new
3V lithium battery (Sony CR2032).
