4-20 NEC Drivers and Utilities
An ISA card connects to a PCI Graphics card via the
VESA-compatible feature connector.
The ISA card connects to a color monitor.
The card uses the RAMDAC on the PCI card.
The palette snooping feature is broken on the PCI card.
Latency Timer (PCI Clock)
The Latency Timer (PCI CLOCK) field controls the length
of time an agent on the PCI bus can hold the bus when
another agent has requested the bus. Value choices range
between 0 and 256; the default value is 66.
In general this should not be changed. If there are
latency-sensitive cards in the system (such as audio cards
and/or network cards with small buffers), this can be set to
a lower value to reduce latency.
If there are no latency-sensitive cards in the system, but I/O
intensive applications are being run, the value can be
increased to slightly improve performance.
Memory Error Detection
Memory Error Detection sets the type of error detection or
correction. This field appears when either ECC or Parity
SIMMs are detected. Parity and ECC (36-bit) SIMMs may
be configured to run as either one. The default is
“Disabled.” The following choices are available.
Disabled (default)
Parity
ECC
