Chapter 1 Introduction to the hme Fast Ethernet Device Driver

This book describes how to configure the hme driver for the SBus or PCI-bus based Sun Ultra workstations, Sun Enterprise servers, the SunSwift SBus Adapter, the SunFastEthernet Adapter 2.0, and the SunFastEthernet PCI Adapter. 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.

With the introduction of Solaris 7, Sun Microsystems now supports a 64-bit version of the Solaris operating environment. With the new 64-bit version, there is a new directory /kernel/drv/sparcv9. In this document and others, note that when kernel/drv is mentioned, the /kernel/drv/sparcv9 directory also applies.
