3.13.7 Manufacturer’s Ethernet ID
Each manufacturer of Ethernet network adapters and interfaces is assigned a unique manufacturer’s ID by
the IEEE Standards Office. A network address consists of 48 bits. The upper 24 bits are the
manufacturer’s ID and the lower 24 bits are the board’s unique ID.
For developers who are creating network applications, knowing the manufacturer’s ID for network
adapters attached to the network may or may not be important.
Ampro’s 24-bit manufacturer’s ID for Ethernet controllers is displayed in hex as follows:
00 40 53
Ethernet IDs are sometimes displayed by diagnostic or network analysis programs in binary format. Refer
to your equipment manual for information on possible byte swapping in the display, as shown in this
example.
0010 1100 1010 0000 0000 0000
3.13.8 Installing a Boot PROM
Most network interface cards provide a means for installing a boot PROM. The boot PROM code enables
the node to boot from a network server, much like the BIOS boots from a local hard disk or floppy.
Boot PROM code varies from one network operating system to another. You must have boot PROM code
compatible with the network operating system you select for use with the onboard LAN controller. Boot
PROMs for Novell Netware, Microsoft Lan Manager, QNX, and other popular network operating systems
are available from LanWorks.
