3.7 PCI Plug and Play Setup
Both the ISA and PCI buses on the CPU card use system IRQs & DMAs. You must set up the IRQ and DMA
assignments correctly through the PCI / Plug and Play Setup utility, otherwise the SBC will not work properly.
When you select the “PCI / PLUG AND PLAY SETUP” on the main program, the screen display will appears as:

PCI/PnP Setup options are displayed by choosing the PCI/PnP Setup icon from the WINBIOS Setup main menu.
All PCI/PnP Setup options are described in this section.
Plug and Play Aware O/S:
Set this option to “ Yes” if the operation system installed in the computer is Plug
and Play-aware. BIOS only detects and enables PnP ISA adapter cards that are required for system boot. The
Windows 95 operating system detects and enables all other PnP-aware adapter cards. Windows 95 is
PnP-aware. Set this option to “ No” if the operating system (such as DOS, OS/2, Windows 3.x) does not use
PnP.
Reset Configuration Data:
This option allows the BIOS to reset the Configuration Data in the BIOS. The
Optimal an Fail-Safe default settings is No.
Option
Description
No
This setting preserves the PnP data. It does not force the PnP data to be
cleared on boot. This is the default setting.
Yes
This option allows the PnP data to be rebuilt by the BIOS at every boot.
PCI Latency Timer (PCI Clocks):
This option is used to control PCI latency timer period (follow PCI clocks).
Based on PCI specification 2.1 or later and PCI bus frequency in system, user can select different timer to meet
their PCI bus environment.
