ECSD will participate in the 2nd European Conference on Earthquake Engineering and Seismology with two papers entitled: Mola, F., Pozzuoli, C., Lo Monte, F., Mola, E., Pasqualato, G., Re, V., Seismic analysis and retrofitting of the highway bridge of the…The large variety of different cards that can be added to PCs to expand their capabilities is both a blessing and a curse.The value “Enabled (On)” is set (and recommended) by default and the interruption will be allocated.Assign IRQ for USB This parameter enables (the value “Enabled (On) – by default) or disables (Disabled (Off)) interruption assignment (IRQ) for USB-devices.In some cases such action allows “revitalizing” the system that refuses to boot normally after adding or deletion of expansion boards.Possible values: Assign IRQ for VGA (Allocate IRQ to PCI VGA) This parameter enables or disables interruption assignment (IRQ) for video adapter.Resources Controlled By This parameter defines the method of allocation of interruptions (IRQ) and channels of direct memory access (DMA).
As the name suggests, the goal is to be able to just plug in a new device and immediately be able to use it, without complicated setup maneuvers.
The BIOS also communicates this information to the operating system, which uses it to configure its drivers and other software to make the devices work correctly.
In many cases older PCs that have an outdated BIOS but otherwise have support for Pn P in hardware (PCI-based Pentiums produced between 19 are the prime candidates) can be made Pn P-compliant through a BIOS upgrade.
As you can see from the other sections that have discussed system resources, configuring the system and dealing with resource conflicts is part of the curse of having so many different non-standard devices on the market.
Dealing with these issues can be a tremendously confusing, difficult and time-consuming task.
