PCI Latency timer translated into Chinese is: PCI delay clock.
This refers to the time that the PCI device monopolizes the PCI bus. The larger the value, the more fully the bandwidth is utilized by the device, but the devices queued later must wait longer before they can start to monopolize the PCI bus and work; therefore A large setting can improve the speed of one device, and a small setting can improve the response efficiency to multiple PCI devices. The default setting for motherboards is generally 32, and the Omega team recommends setting it to 64.
Extended information:
BIOS (Basic Input and Output System) factory settings:
1. PNPOSInstalled (whether to install the PNP operating system, the default value is No) ?
When using an operating system with Plug and Play (PNP) function (such as Windows95, 98), you can select Yes. ?
2. SlotXIRQ (interrupt value of PCI slot, default value is Auto)?
Used to set the IRQ value of each PCI slot, the items include NA, 9 , 10, 11, 12, 13, 14, 15, and Auto (that is, automatically set by the BIOS)
3. PCILatencyTimer (default value is 32PCIClock)?
Use "32PCIClock" "It will make the PCI speed of the motherboard the fastest. ?
4. IRQXXUsedByISA (default value is No/ICU)?
Used to reserve a specific IRQ for non-PnP ISA cards. ?
5. DMAXXUsedByISA (default value is No/ICU)?
Used to reserve specific DMA channels for non-PnP ISA cards. ?
6. ISAMEMBlockBASE (default value is No/ICU)
The block size and address used to reserve the memory for the ISA card. ?
7. SYMBIOSSCSIBIOS (default value is Auto)?
For this function, you can select Auto to enable the built-in NCRSCSIBIOS. You can select Disable to cancel this function. ?
8. USBFunction (universal port function setting, the default value is Disable)?
This function is used to enable the USB function. This motherboard can support universal port function. USB port (US), but the current operating system does not yet support the USB function, so the default value is (disable).
