Disclaimer:
!
This motherboard incorporates support for 75MHz and 83MHz BUS
speeds. However, these speeds will push PCI bandwidth beyond the Intel-
recommended specification for PCI 2.1 compliance. Therefore, TYAN
Computer Corporation takes no responsibility for any problems, be they
hardware or software, related to the use of BUS speeds beyond 66MHz.
We also cannot guarantee any PCI cards' compatibility beyond the speci-
fied speed of 33MHz. Technical support and RMA/Warranty claims re-
lating to the use of BUS speeds beyond the 66MHz/33MHz limit recom-
mended by Intel will not be honored by TYAN. Use at your own risk.
Windows 95 Users:
You may encounter problems with some of the devices in the Intel
82371AB chip. Neither the PCI Bridge nor the PCI Universal Serial BUS
device IDs for this chip (also called PIIX4) are recognized by Windows
95. This is a software problem, not a hardware problem, and can be eas-
ily remedied by either upgrading to Windows 98 or downloading the
82371AB patch found at http://www.tyan.com or at ftp://
download.intel.com/design/pcisets/busmastr/setupex.exe. (Note: USB
requires Windows 95 OSR 2.1 or above; please contact Microsoft for
USB update.)
CMOS RTC
The 430TX chipset includes an internal battery
and Real Time Clock circuit. The RTC pro-
vides the date and time for the system. If the
battery is low, it will prevent your system from
J8
POSTing, and you will not get a display.
Normally the life span of an RTC internal
battery is 10 years, but if yours is running low, you will need to replace
it with a new 3V lithium battery (Duracell DL2032).
Soft Power Connector
The Soft Power Connector is located on pins 1 and 2 of jumper block
18
