4.3.5.2Clear NVRAM
This option is used to clear NVRAM and check or update ESCD (Extended System Configuration Data) data after system power on. Set this option to No that will not clear NVRAM and the operation of update ESCD is effective in different ESCD data comparison. If you select the “Yes” setting, then the BIOS will update ESCD each time of power on.
4.3.5.3PCI Latency Timer (PCI Clocks)
This option sets the latency of all PCI devices on the PCI bus. The settings are in units equal to PCI clocks. The settings are 32, 64, 96, 128, 160, 192, 224, or 248. The Optimal and
4.3.5.4PCI / VGA Palette Snoop
Leave this field at Disabled.
Choices are Enabled, Disabled.
4.3.5.5Allocate IRQ to PCI VGA
Enable/Disable to assign a IRQ for PCI VGA.
Choices are Yes, No.
4.3.5.6PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local bus supports bus mastering capability. The settings are Disabled or Enabled. The default setting is Disabled.
4.3.5.7DMA Channel 0/1/3/5/6/7
Legacy ISA for devices compliant with the original PC AT bus specification, PCI/ISA PnP for devices compliant with the Plug and Play standard whether designed for PCI or ISA bus architecture.
Choices are ISA/EISA and PnP.
4.3.5.8IRQ3/4/5/7/9/10/11/14/15
These options specify the bus that the named interrupt request lines (IRQs) are used on. These options allow you to specify IRQs for use by legacy ISA adapter cards. These options determine if AMIBIOS should remove an IRQ from the pool of available IRQs passed to BIOS configurable devices. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the pool, the end user can use these PCI/PnP Setup options to remove the IRQ by assigning the option to the ISA/EISA setting. Onboard I/O is configurable by AMIBIOS. The IRQs used by onboard I/O are configured as PCI/PnP. The settings are PCI/PnP or ISA/EISA. The default settings are PCI/PnP.
