WARNING:
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, hardware or software, related to the
use of BUS speeds beyond 66MHz. We also cannot guarantee any PCI cards’
compatibility beyond the specified speed of 33MHz. Technical support and
RMA/Warranty claims relating to the use of BUS speeds beyond the 66MHz/
33MHz limit recommended by Intel will not be honored by TYAN.
Use at your
own risk.
