Broadcom BCM570x EFI Driver for IA-32 and IA-64
04/22/2002
Introduction
============
This file describes the EFI driver for Broadcom's BCM570x
10/100/1000 Mbps Ethernet Network Interface Controller. Driver is
released as a standard EFI driver format and library binary (intended
for LOM application) for both EFI core firmware 1.0.2 and 1.1.
1. b57undi32.efi : EFI driver for IA-32 platform.
2. b57undi64.efi : EFI driver for IA-64 platform.
3. b57undi32.lib : EFI driver for IA-32 platform in library format.
4. b57undi64.lib : EFI driver for IA-64 platform in library format.
Driver Installation
===================
Drivers for core firmware v1.02 and v1.1 are built based on EFI SDK 1.02.12.38
and EFI SDK 1.1.14.5x, respectively. The same version of the efildr should be
used on IA32 systems. The driver is compatible with efildr that is deployed
on most IA64 systems.
1. Boot into EFI shell.
2. Load b57undi32.efi in IA-32 platform
OR
Load b57undi64.efi in IA-64 platform
3. If SNP is loaded by core firmware then skip to step 4. Otherwise,
Load snp3264.efi.
4. For drivers running on core firmware v1.10.50, then start the drivers
connect -r
5. Once driver is loaded, TCP/IP stack can be loaded into the memory
as follows:
load tcpipv4.efi
6. Configure interface as follows
ifconfig sni0 30.2.1.1 up
7. Ping remote station, etc....
Integration driver with EFI core firmware for LOM applications
=============================================================
1. Link b57undi32.lib or b57undi64.lib to EFI core firwmare for
IA-32, or IA-64 platform, respectively.
2. Driver can be started with EFI macro
LOAD_INTERNAL_DRIVER(FW,
IMAGE_SUBSYSTEM_EFI_BOOT_SERVICE_DRIVER,
L"B57undi",
UM_InitializeUNDIDriver);
Where UM_InitializeUNDIDriver is the main entry point of this
driver.
3. If the EFI core firmware is version 1.1, then make sure the
the following EFI core driver libraries are linked to EFI
core firmware:
$(EFI_SOURCE)\Edk\Lib\EfiDriverLib\EfiDriverLib.lib
$(EFI_SOURCE)\Edk\Lib\Print\Print.lib
$(EFI_SOURCE)\Edk\Protocol\Protocol.lib
$(EFI_SOURCE)\Edk\Guid\Guid.lib
Revision History
================
v2.1.5 (04/22/02) - Fixed a problem where driver doesn't work in some PCI-X systems.
v2.1.4 (03/21/02) - Fixed a problem where BCM5700C2 NIC does not work at
if connection is changed from 100Mbps to 1Gbps. (CQ3711)
- Added support for different LED configurations.
v2.1.3 (03/20/02) - Fixed a problem where BCM5700C2 NIC does not work at
100Mbps. (CQ3605)
- Fixed a problem where no device path found for BCM5700B2.
(CQ3586)
v2.1.2 (02/24/02) - Added support for Ethernet WireSpeed feature for
BCM5702/BCM5703 NICs/LOMs.
- Added support for NICs with device ID 0x16a6 and 0x16a7.
- Added machanism to protect serial EEPROM corruption.
v2.1.1 (02/12/02) - Fixed a banner typo.
v2.1.0 (02/02/02) - Fixed a problem where driver doesn't work in EFI 1.10.54
core firmware environment.
v2.0.5 (11/19/01) - Added description of what slot (PCI or PCI-X) the NIC/LOM is
installed on when it's detected.
- Released EFI driver in library format for LOM application.
v2.0.4 (11/16/01) - Added support for EFI core firmware v1.1.
- Fixed a problem where performance of TCP/UDP traffic
is intermittently slow.
v2.0.3 (10/29/01) - Built specificially for core firmware V1.02.12.32 and
older. This version of driver doesn't raise/restore
priority level as done to work around an issue
in SNP module of core firmware v1.02.12.36 Or newer.
v2.0.2 (10/26/01) - Fixed a problem Bond ID is not checked correctly.
v2.0.1 (10/19/01) - Added support for BCM5702 and BCM5703 NICs/LOMs.
v2.0.0 (09/06/01) - Fixed a problem where application (pktsnoop) cannot
monitor packet with invalid 802.3 length fields.
- Fixed a problem where system intermittently crashes during
continous file transfer.
- Added Fiber NIC support.
v0.03 (08/31/01) - Added support for BCM5701.
- Fixed problem with loading driver on IA-32 (CQ#2009).
- Fixed problem when assigning IP address on IA-32 (CQ#2300).
- Fixed pktxmit.efi crashing problem (CQ#2302).
- Added a workaround to minimize the race condition on SNP
v0.02 (08/18/01) - Fixed problem with ping on IA-64 (CQ#1960).
v0.01 (05/14/01) - First Release.
Known Problems
==============
1. Since the driver is built based on the latest EFI SDK (v1.02.12.38), it may
not work with the efildr of the previous version on IA32. However, it is
compatible with the efildr that is deployed on most IA64 systems
(v1.02.12.36a).
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
