Broadcom BCM570x EFI Driver for IA-32 and IA-64
05/08/2003
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.
5. b57ebc.efi : EFI driver in EBC format. This driver will work
in environment if EBC intepreter is present.
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. This driver has been tested with EFI core firwmare
1.10.14.57 and 1.10.14.59 and comply with EFI v0.95. This driver doesn't
support pre-release of EFI 1.10.50 core firmware.
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. Once driver is loaded, TCP/IP stack can be loaded into the memory
as follows:
load tcpipv4.efi
5. Configure interface as follows
ifconfig sni0 30.2.1.1 up
6. 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
Integration driver with Option ROM
==================================
1. Use provided utility, efirom.exe, to convert EBC driver into EFI ROM
format. It's worthy to note that utility efirom.exe is a DOS
application which can be executed in stardard DOS or DOS box
in Windows environment.
For instance,
This driver is intended to program on BCM5702-based NIC
with vendor ID of 0x14e4 and device ID of 0x16a6
efirom -v 0x14e4 -d 0x16a6 -o rom.bin -ec -cc 2 b57ebc.efi
This driver is intended to program on BCM5701-based NIC
with vendor ID of 0x14e4 and device ID of 0x1645
efirom -v 0x14e4 -d 0x1645 -o rom.bin -ec -cc 2 b57ebc.efi
The output file rom.bin, which is in compressed EFI format, can be
programmed to NIC's NVRAM.
2. Use utility (b57diag.exe or b57diag32.efi/b57diag64.efi) to program
option ROM image to NIC's NVRAM. Follow the following steps:
* Enter diagnostic shell,
b57diag64.efi -b57eng
* Use "device" command to select device to be programmed if there
are more 1 device.
* upgfrm -ffs0:\rom.bin -p
* setpxe -e
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.
