(EOL) components are products that are no longer supported by the manufacturer. EOL components are products that may have been recently discontinued, but are still available in the marketplace. The manufacturer of an EOL component may still offer limited support for its installed base of customers.In some cases, current operating systems and applications will not work properly with EOL products. Generally, drivers are no longer researched and developed for legacy and EOL components.
3.)When using EOL components, it is important to verify compatibility with the system. If possible, check with the manufacturer for any known compatibility issues, and the availability of optimized drivers for the system. If the manufacturer is no longer available, it may be best to consider replacing this component with a similar one that is currently manufactured.
