3.10 Typical Resource Allocation For Windows 98
In any computer it is critical to have a good understanding of the computer’s
resource allocation. Compatibility with previous standards requires the system to
have a specific hardware environment for interrupts, DMA and memory address.
The 8570 Vehicle-Mount Computer uses plug and play technology. This means the
resource allocation can be controlled by software. Typical resource allocations are
shown in Table 3.1 "Typical Resource Allocations - IRQs" through Table 3.3
"Typical Resource Allocations - Memory". Looking at IRQ allocations from 0 to 15,
you will note that most of them are already assigned.
Reallocating resources like IRQs can be done at different levels. At the BIOS level
you can turn on or off devices such as COM ports, freeing those IRQs for other uses.
Another level of control is from a plug and play operating system such as Windows
98, where the device manager allows you to control resources.
