The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in  the configurations section  has been sourced  from the
second.

This  chip was  used on  the Pentium  66MHz CPU  complexes of  Intel's
Xpress platform.   Specifically the  BXCPUPENT66 (Single  66MHz, eight
82491s) and BXCPU2XPENT (Dual 66 MHz,  eight 82491s). Also found on P5
60/66MHz CPU complexes of IBM 9595/PC Server 300/500 systems.
