GEM(4) FreeBSD Kernel Interfaces Manual GEM(4) NAME gem -- ERI/GEM/GMAC Ethernet device driver SYNOPSIS device miibus device gem DESCRIPTION The gem driver provides support for the GMac Ethernet hardware found mostly in the last Apple PowerBooks G3s and most G4-based Apple hardware, as well as many Sun UltraSPARCs. HARDWARE Cards supported by gem driver include: +o Sun GEM gigabit Ethernet +o Sun ERI 10/100 Mbps Ethernet +o Apple GMAC NOTES On sparc64 the gem driver respects the local-mac-address? system configu- ration variable which can be set in the Open Firmware boot monitor using the setenv command or by eeprom(8). If set to ``false'' (the default), the gem driver will use the system's default MAC address for all of its devices. If set to ``true'', the unique MAC address of each interface is used if present rather than the system's default MAC address. Supported interfaces having their own MAC address include the on-board Sun ERI 10/100 Mbps and GEM gigabit Ethernet Interfaces on boards equipped with more than one Ethernet interface and the Sun GEM gigabit Ethernet add-on cards. SEE ALSO hme(4), miibus(4), netintro(4), eeprom(8), ifconfig(8) HISTORY The gem device driver appeared in NetBSD 1.6. The first FreeBSD version to include it was FreeBSD 5.0.
