MDA Support [No]
Leave on the default setting [No] unless you are using a monochrome display adapter
(MDA).
PCI Delay Transaction [Enabled]
When [Enabled], this frees the PCI Bus during CPU accessing of 8-bit ISA cards
that normally consume about 50-60 PCI Clocks without PCI delayed transaction. If
PCI Bus Masters cannot use the PCI Bus, select [Disabled] for some ISA cards that
are not PCI 2.1 compliant.
ISA Bus Clock [PCICLK/4]
Leave on default settings.
ClkGen Spread Spectrum [Enabled]
Leave on default setting. Spread spectrum typically reduces system electromagnetic
interference (EMI) by 8dB to 10dB.
ClkGen for Empty PCI Slot/DIMM [Enabled]
When enabled, this feature generates clock signals for empty PCI slots and DIMM
sockets. Disabling this feature will save power and reduce EMI.
