Chassis Intrusion Alarm Connector
The J8 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J8 is closed), this alarm will alert the system administra-
tor anytime someone opens the system’s case.
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 by installing the Win-95 Patch found on the Tyan
Driver CD and on the Tyan internet and ftp sites: 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. Normally
the life span of an external battery is 2 years. If yours is running low, you will
need to replace it with a new 3V lithium battery (Sony CR2032).
Flash EEPROM
The Tiger 100 uses flash memory to store BIOS
programs. It can be updated as new versions of
the BIOS become available. You can upgrade your
BIOS easily using the Flash Writer Utility (see
page 69).
