The above features control the memory buffer strength. They are
used to program the various DRAM interface signal buffer
strengths, based on memory configuration, DRAM type (EDO or
SDRAM), DRAM density (x4, x8, x16, or x32), DRAM technology (16
Mb or 64 Mb), and rows populated. Note the Optimal and Fail-
Safe default settings are Auto.
PAC Bus SERR#
The settings for this option are: Disabled or Enabled. When set
to Enabled, the PAC's SERR# signal driver is enabled and
SERR# is asserted for all relevant bits set in the ERRSTS and
PCISTS as controlled by the corresponding bits of the ERRCMD
register. When Disabled, SERR# is never driven by the PAC.
AGP Common SERR#
The settings are: Disabled or Enabled. Set to Enabled to permit
a common SERR# signal for AGP and the standard PCI bus.
AGP System Error Forwarding
The settings are: Disabled or Enabled. Set this option to Enabled
to enable AGP systems errors to be forwarded.
AGP Parity Error Response
The settings are: Disabled or Enabled. Set this option to Enabled
to enable AGP parity error response.
IRQ12
The settings are: Auto, Standard or Mouse. When this option is
set to Auto the AMIBIOS automatically determines how IRQ12
should be allocated.
In the Standard setting IRQ12 is made
available for use on the ISA bus. IRQ12 is used by the PS/2
Mouse, when in Mouse setting.
