Dual-550 PCI

Windows device driver information for Dual-550 PCI

The Dual-550 PCI hardware component is ideally installed in computer systems which require manually setting addresses for the COM and IRQ of the underlying operating system environment. This expansion card allows for the doubling of the number of ISA card slots currently present in the computer motherboard of the host machine. The device itself is supported by a device driver which provides the computer user with the flexibility of dictating numerous IRQ and COM settings while helping to minimize potential conflicts with current hardware addressing. This means that the host computer system is given more alternatives when it comes to assigning and allocating system resources. Basically, every hardware component attached to a host computer system requires the allocation of system resources and addressing. This is necessary to help requesting software applications find the correct hardware component to execute its tasks based on the address it retrieves from the registry database.

The entries in the registry database is essentially dictated by the device driver for the supported hardware component. This is primarily because every device driver functions as some type of information and layout file that will provide the operating system environment with the information it needs to make the supported device functional. All data provided by the device driver are stored in a centralized registry database which is available to all installed software applications. When properly installed with the manufacturer provided device driver the Dual-550 PCI can provide two additional high speed 16550 UART type serial ports provided that the host machine has an available ISA slot. This also translates to the device driver supporting faster data transfer rates because basically serial ports can implement a maximum of 115.2 kilobits per second data transfer throughput. The device driver also allows for the individual configuration of the serial ports which are subsequently numbered consecutively from COM1 to COM6. It is highly recommended you run a free registry scan for and Dual-550 PCI errors before installing any driver updates.
