The Intel 82566DM Gigabit Ethernet PHY, a network interface controller, offered high-speed wired connectivity. Operating at Gigabit Ethernet speeds, it facilitated rapid and reliable data transmission within networks. Its advanced features included support for Wake-on-LAN, enhancing power management capabilities for remote wake-up functionality. Utilized in desktops and servers, it provided stable and efficient wired network connections. However, as technology progressed, the emergence of faster networking standards and interfaces eventually phased out the 82566DM, marking it as a legacy solution in the landscape of Ethernet controllers.
