16 CHAPTER 2: 3CR990 NICS
The following figure shows the 3CR990 NIC and the location of its
major components.
NIC Features The 3CR990 NICs provide these features for supported IP and IPX environments:
■ Integrated Boot ROM
■ Remote Wake-Up
■ Desktop Management Interface (DMI)
■ DHCP server prevention
■ Broadcast storm limitation
■ Offline diagnostics
Integrated Boot ROM Managed PC Boot Agent (MBA) software provides the multiprotocol preboot
firmware and tools. MBA adds management capabilities to the NIC by enabling
the PC to boot from a network server, rather than from its local drive. 3CR990
NICs have an integrated boot ROM already installed on the NIC.
For information on configuring and using the MBA, see the Managed PC Boot
Agent (MBA) User Guide located on the EtherCD. Navigate the following path:
