Dell
•
Common interrupt vector as a disk drive
iSCSI boot operates in two phases:
•
Pre-OS iSCSI boot option ROM will establish a connection to an iSCSI target using statically configured
parameters or dynamically.
•
After establishing an iSCSI connection to a remote iSCSI target, the iSCSI boot host software will also
install a legacy Int13h style interface to allow the remote iSCSI target to act as if it were a local hard
drive.

Diagnostic Tests

11.12
The Diagnostic Tests option on the Diagnostics tab lets you check the state of the physical components on a
Broadcom network adapter. You can trigger the tests manually, or choose to have BACS 3 continuously
perform them. If the test are performed continuously, then the number of passes and fails in the Status
field for each test increments every time the tests are performed. For example, if a test is performed four
times and there are no fails, the value in the Status field for that test is 4/0. However, if there were 3
passes and 1 fail, the value in the Status field is 3/1.
Notes:
• You must have administrator privileges to run diagnostic tests.
• The network connection is temporarily lost while these tests are running.
• This option is available for Broadcom NetXtreme II VBD drivers.
• Some tests are not supported on all Broadcom adapters.

Flow Control

11.13
Enables or disables the receipt or transmission of PAUSE frames. PAUSE frames allow the network adapter
and a switch to control the transmit rate. The side that is receiving the PAUSE frame momentarily stops
transmitting.

Network Controller Sideband Interface (NC-SI)

11.14
BCM5716C support NC-SI. Industry standard. NC-SI is used to enable a common interface definition between
different Management Controller and Network Controller for out-of-band manageability and functionality
such as Remote Media (R-Media) and Remote Keyboard-Video-Mouse (R-KVM). This specification addresses
not only the electrical and protocol specifications, but also the system-level behaviors for the Network
Controller and the Management Controller related to the NC-SI.

IPv4 and IPv6 Checksum Offload

11.15
Normally, the checksum function is computed by the protocol stack. When you select one of the Checksum
Offload property values (other than None), the checksum can be computed by the network adapter.
• Rx Enabled. Enables receive TCP/IP/UDP checksum offload.
• Tx Enabled. Enables transmit TCP/IP/UDP checksum offload.
• Tx/Rx Enabled (default). Enables transmit and receive TCP/IP/UDP checksum offload.
• None. Disables checksum offload.
