KX7-333/KX7-333R Introducing the BIOS 3-19 CPU & PCI Bus Control: This item can let you sets several items concerning the PCI parameters. If you do not understand what each item does, please keep the default settings as well. CPU & PCI Bus Control Screen PCI Master Read Caching: Two options are available: Disabled or Enabled. PCI Master Bus Time-Out: Eight options are available: Disabled ( 001 ( 010 ( 011 ( 100 ( 101 ( 110 (111. It can set the time-out period, when after the set time-out period, PCI bus master will force into arbitration. Master Priority Control: Four options are available: Disabled ( 01 ( 10 ( 11. When setting to "01", the CPU will always be granted access after the current bus master completes, no matter how many PCI masters are requesting. With setting to "10", if other PCI masters are requesting during the current PCI master grant, the highest priority master will get the bus after the current master completes. But the CPU will be guaranteed to get the bus after that master completes. With setting to "11", if other PCI masters are requesting, the highest priority will get the bus next, then the next highest priority will get the bus, then the CPU will get the bus. In other words, with the above settings, even if multiple PCI masters are continuously requesting the bus, the CPU is guaranteed to get access after every master grant (01), after every other master grant (10) or after every third master grant (11). User's Manual 3-20 Chapter 3 PCI1 Master 0 WS Write: Two options are available: Enabled or Disabled. When Enabled, writes to the PCI1 bus are executed with zero wait state (immediately) when PCI1 bus is ready to receive data. If it is set to Disabled, the system will wait one state before data is written to the PCI1 bus. PCI2 Master 0 WS Write: Two options are available: Enabled or Disabled. When Enabled, writes to the PCI2 bus are executed with zero wait state (immediately) when PCI2 bus is ready to receive data. If set to Disabled, the system will wait one state before data is written to the PCI2 bus. When you set it to Enabled, it can enable PCI post write buffers to minimize PCI1 master read latency.
