Details of Chipset Features Setup
Auto Configuration (60ns DRAM)
The default setting of
60ns DRAM
sets the optimal timings for items 2 through 9 for
60ns DRAM modules.
If you are using 70ns DRAM modules, you must change this
item to
70ns DRAM
.
See section III for DRAM installation information.
Peer Concurrency
(Leave on default setting of
Enabled
)
PCI Streaming
(Leave on default setting of
Enabled
)
Passive Release (Enabled)
This is a mechanism that allows concurrency of ISA/EISA cycles and CPU-to-PCI
cycles.
When this feature is enabled, the TXC will be possible to re-arbitrate PCI
bus and allow the CPU to access PCI even when the PCEB has been granted the bus.
Chipset Global Features
(Leave on default setting of
Enabled
)
16-bit I/O Recovery Time (1 BUSCLK)
Timing for 16-bit ISA cards
8-bit I/O Recovery Time (1 BUSCLK)
Timing for 8-bit ISA cards
