Switching between network interface cards during different stages of operation
View Patent ↗In one embodiment, a network boot program is received from a server via a first network interface controller associated with a first network identifier. The network boot program is executed. An operating system loader comprising an operating system driver is received from the server via the first network interface controller. The operating system driver identifies a second network interface controller associated with a second network identifier. The operating system driver associates the first network interface controller with the second network identifier and associates the second network interface controller with the first network identifier.
