The AMD-K6-IIIE+ processor is designed with enhanced power
management features, called AMD PowerNow! technology,
which include dynamic bus divisor control and dynamic core
voltage control. The EPMR register (see Figure 43) defines the
base address for a 16-byte block of I/O address space. Enabling
the EPMR allows software to access the EPM 16-byte I/O block,
which contains bits for enabling, controlling, and monitoring
the AMD PowerNow! technology features. The EPMR is MSR
C000_0086h.
See “AMD PowerNow!™ Technology” on page 143 for more
information about the definition and use of this register.
Additional information can be found in the Embedded
AMD-K6™ Processors BIOS Design Guide Application Note, order#
23913.
