CIM_LogicalElement 89
The CIM_SystemResource class listed in Table 3-39 provides access to
system resources from an operating system. SystemResources consist of
interrupt requests (IRQs) and direct memory access (DMA) capabilities.
CIM_IRQ
The CIM_IRQ class described in Table 3-40 contains IRQ information. An
IRQ is a signal that data is about to be sent to or received by a peripheral
device. The signal travels by an IRQ line to the microprocessor. Each
peripheral connection must be assigned an IRQ number. For example, the
first serial port in your computer (COM1) is assigned to IRQ4 by default.
