NAME

gem - ERI/GEM/GMAC Ethernet device driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:
device miibus device gem

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

 if_gem_load="YES"
 

DESCRIPTION

The 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

Chips supported by the driver include:

The following add-on cards are known to work with the driver at this time:

NOTES

On sparc64 the driver respects the local-mac-address? system configuration 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 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 on boards equipped with more than one Ethernet interface and the Sun Gigabit Ethernet 2.0/3.0 GBE add-on cards.

CAVEATS

Currently the driver fails to attach to Sun Gigabit Ethernet SBus 2.0/3.0 (GBE/S) cards, as no SBus front-end has been written so far.
