IntroductiontothehmeFast
EthernetDeviceDriver 1
This book describes how to configure the hme driver for the SunUltra1
Series systems, the Sun Ultra 2 Series system, the UltraEnterprise3000,
4000, 5000, and 6000 systems, the SunSwiftSBus Adapter, and the
SunFastEthernetAdapter 2.0. To configure the hme driver you can use the
ndd utility to set the parameters. If you use the ndd utility, the parameter
values are effective until you reboot the system. To keep the values in effect
even after rebooting the system, enter the parameter values into the
/etc/system file or the hme.conf file in the /kernel/drv directory.
Chapter 2 describes the hme device driver and includes topics such as
operating speeds and modes, auto-negotiation, the internal transceiver, and the
external transceiver. Chapter 3 describes the parameters and settings for the
hme device driver. Chapter 4 describes how to set the hme device driver
parameter values using the ndd utility and also in the /etc/system and
hme.conf files.
