Broadcom Corporation 16215 Alton Parkway, Irvine, CA 92619-7013 Release Note Broadcom BCM570x Mutiple Boot Agent (MBA) [ PXE (Preboot Execution Environment) and RPL (Remote Program Load) ] 03/25/2002 ******************************** IMPORTANT NOTE ******************************* * * * All of the released binary images (except b57base.bin and b57mba.lom) have * * standard ROM header which has embeded Vendor ID/Device ID. BIOS only loads * * MBA image if Vendor ID/Device ID matches the Vendor ID/Device ID of the * * controller. The default Vendor ID/Device ID in the released images are for * * BCM5701 controller (0x14e4/0x1645). If this image is programmed to NIC * * without using Broadcom's flashing utilities such as b57util.exe or upgfrm * * command in b57diag.exe, then the provided romhdr.exe must be used to update * * ROM header with the Vendor ID/Device to match with intended controller. * * Similarily, in LOM application where MBA image is integrated to BIOS, it's * * mandatory to use romhdr.exe to update image's ROM header to match with * * intended target controller's Vendor ID/Device ID. * * * ******************************************************************************* Introduction ============ This file describes the Broadcom Multiple Agent for Broadcom's BCM570X 10/100/1000 Mbps Ethernet Network Interface Controller. Broadcom Multiple Boot Agent (MBA) supports PXE and RPL. Multiple Agent driver is released in the following binaries: b57pxe.bin: This is a monolithic image that consists of both base-code (BC) and UNDI code. This image should be used on the adapter where motherboard doesn't have built-in BC. However, an adapter programmed with this image is still operational in the motherboard's BIOS with built-in BC; the BC on the adapter will not be used. This image only supports PXE. b57undi.bin: This is an UNDI image that consists of UNDI code only (split implementation) which is intended for NIC application. b57base.bin: This is a BC image that consists of BC code only (split implementation) which is intended for LOM application. This module should be programmed on the motherboard's BIOS. This base-code only supports PXE. b57mba.lom: This is a BC image that consists of BC code only (split implementation) which is intended for LOM application. This module should be programmed on the motherboard's BIOS. This base-code supports PXE and RPL. b57undi.lom: This is an UNDI image that consists of UNDI code only (split implementation) which is intended for LOM application. This module should be programmed on on the motherboard's BIOS. b57pxe.lom : This is a monolithic image that consists of both base-code (BC) and UNDI code. This image is intended for LOM application. This image only supports PXE. b57mba.nic : This is a monolithic image that consists of both base-code (BC) and UNDI code. This image is intended for NIC application. This image only supports PXE and RPL. romhdr.exe : This tool can be used to customize PXE image for different ASIC-based LOM applications. It basically modifies the Vendor ID/Device ID in the ROM header of the image and then recalculates the checksum. For instance, use b57undi.lom for BCM5700-based LOM. romhdr -v 0x14e4 -d 0x1644 -i b57undi.lom Application =========== Some example applications are used to clarify the usage of these binary images. 1. BCM570X LOM with PXE and RPL support: b57mba.lom and b57undi.lom should be integrated with system BIOS. 2. BCM570X LOM with PXE support ONLY: b57base.bin and b57undi.lom should be integrated with system BIOS. 3. BCM570X NIC with PXE and RPL support: b57mba.nic should be programmed to NIC's NVRAM (serial EEPROM/FLASH). 4. BCM570X NIC with PXE ONLY support: b57pxe.nic should be programmed to NIC's NVRAM (serial EEPROM/FLASH). Revision History ================ Version 2.2.6: 1. Fixed a problem where it fails to operate with a certain model of Cisco switches. Whenever there is a link change, Cisco switch doesn't forward packets after 5 to 10 seconds even spanning tree protocol is disabled. It drops all packets during this period of time. Base-code is changed to retry more times. However, Cisco switch can be configure to work with previous versions of PXE. The workaround is to configure Cisco port, where PXE client is connected to, to portfast mode. For instance, set spantree portfast 4/12 enable 2. Enhanced so that wait time for physical link stability is shortened. Version 2.2.5: 1. Optimized phase2 loader and minimized serial EEPROM corruption (This applies to NIC application ONLY). Version 2.2.4: 1. Added support for different LED configurations. Version 2.2.3: 1. Fixed a problem Dell PowerEdge7150 (Dual Processor IA-64) hangs up during EFI initialization if PXE-enabled NIC is installed. This problem is caused by a bug in EFI IA-64 core firmware where it passes invalid PCI bus/device/function parameter to UNDI. Workaround around is implemented by using initial parameter passed during UNDI init. (CQ3534) 2. Fixed a problem where HPi2000 (IA-64 system) intermittently doesn't boot if PXE-enabled NIC is installed. Version 2.2.2: 1. Fixed a problem where AutoNeg of Fiber NIC might not work on a certain systems. (CQ3462) 2. Rebooted system if RPL downloading fails. (CQ3606) Version 2.2.1: 1. Added software workaround for high bit error rate with 5703S fiber. Version 2.2.0: 1. Added Remote Program Load (RPL) support. Since it's implemented based on IBM standard, it should interoperate with RPL service running on popular O/S such as Windows NT and IBM OS/2. However, It will not work with Novell Netware yet since bootstrap (downloaded via RPL) requires ODI driver interface to download the rest of image with Netware protocol (Netware Core Protocol - NCP). This features should allow users to remote/boot/install DOS/Win95/ Win98/OS2. 2. Fixed PXE version banner. (CQ3435). Version 2.1.8: 1. Added support for Ethernet WireSpeed feature for BCM5702/ BCM5703 NICs/LOMs. 2. Added support for NICs with device ID 0x16a6 and 0x16a7. 3. Fixed a problem where EFI UNDI core firmware detects UNDI16 with zero MAC address (CQ3337). Version 2.1.7: 1. Added support for BCM5702/BCM5703 (Rev. A0 silicon). Version 2.1.6: 1. Changed so that PXE cannot be loaded if ASF is enabled. 2. Added scheme to prevent serial EEPROM corruption in BCM5702/BCM5703. Version 2.1.5: 1. Fixed a problem where DOSUNDI hangs up with BCM5703 NICs (CQ3113) 2. Fixed a problem where PXE performance is slow on BCM5702/BCM5703 NICs (CQ3125). 3. Fixed a problem where PXE is slow then BCM5701 NICs is on the Dual AMD Tyan (CQ3165). 4. Fixed a problem where UNDI performance is slow when it's in some of OEM PCI-X systems. (CQ2800). Version 2.1.4: 1. Removed personized banner per OEM's request. 2. Added features to allow user to configure delay time for banner, and boot strap type (BBS,INT18h, INT19h). Version 2.1.3: 1. Fixed a problem where PXE might lock up in some systems which implement "Fast Boot Initiative". This only happens on NICs but not LOMs. It's neccessary to have to use latest tools to upgrade PXE and latest boot code firmware. Version 2.1.2: 1. Fixed a problem where UNDI speed is very slow when BCM5701 Fiber NICs/LOMs on a certain platform. Version 2.1.0: 1. Fixed a problem where PXE doesn't work with BCM5702/BCM5703 NICs. Version 2.0.11: 1. Fixed a problem where download with MTFTP fails. (CQ1793 & CQ2679) Version 2.0.10: 1. Added support for future BCM5702 and BCM5703 NICs/LOMs. Version 2.0.9: 1. Fixed a problem where PXE is not operatable if preboot WOL is enabled. Version 2.0.8: 1. Improve performance. Version 2.0.7: 1. Fixed a problem where Tx or Rx can be hung when it's in PCI-X. Version 2.0.6: 1. Fixed a problem where PXE is not detected by BIOS when it's in PCI-X slot. Version 2.0.5: 1. Fixed a problem where PXE might not boot in some systems which have SMBIOS database built at preboot but don't support BBS. Version 2.0.4: 1. Enhanced so that BIOS's BBS capability can be detected though SMBIOS. Version 2.0.3: 1. Added support for BCM95701A12 NIC. 2. Enhanced to utilize shared memory interface for future compatibility. Version 2.0.2: 1. Added support for BCM95701A10 NIC. Version 2.0.1: 1. Added BCM5700 Fiber NIC support. 2. Added BCM5701 Fiber NIC support. 3. Added support for some OEM NICs. Version 2.0.0: 1. Added BCM5701 support. Version 1.06: 1. Added PCI-X workaround for B2 silicon. Version 1.05: 1. Changed to provide a scheme for users to boot via Int 18h, Int 19h, or BBS. After the Broadcom banner is displayed, users have 4 seconds to select: * Ctrl F8 : Int 18h * Ctrl F9 : Int 19h * Ctrl F10 : BBS 2. Changed to allow users to force PXE run at a certain speed. Version 1.04: 1. Changed due to changes in ASIC version format in B1 silicon. Version 1.03: 1. Eliminated unused code to save more memory so that it works fine with IBM 300GL. 2. Changed to accomodate different LED configurations based on System Vendor ID. Version 1.02: 1. Fixed a problem where client hangs up during setup phase of windows 2000 installation with RIS. 2. Fixed copyright banner string. Version 1.01: 1. Changed to accomodate different LED configurations. Version 1.0: 1. Fixed a problem where base-code cannot be unloaded. 2. Fixed a problem where Linux Universal Driver crashes when it binds to UNDI. UNDI now can run in protected mode. Version 0.10: 1. Fixed a problem where some system might lock up if BIOS calls UNDI API SHUTDOWN before call UNDI API INITIALIZE. IBM 300PL PC is one of them. 2. Changed so that Broadcom copyright banner is displayed during ROM initialization. This version should fix SAR Prod0000344,and SAR Prod0000283 Version 0.9: 1. Fixed a problem where PXE is not recognized is some systems where BIOS don't support BBS (BIOS Boot Specification). Logic is added to PXE initialization code to detect if BIOS support BBS or not. If not, then use Interrupt 18h for boot. This should fix SAR Prod0000225,SAR Prod0000604, SAR Prod0000606. Version 0.8: 1. Fixed a problem where APITEST failed. (SAR Prod0000426) Version 0.7: 1. Fixed a problem where mapping a network drive can intermittently lock up the client system. (SAR Prod0000236) Version 0.6: 1. Fixed a problem where PHY speed for Gigabit links are not displayed correctly. Version 0.5: 1. Added support for B0 Silicon. 2. Fixed a problem where 10Mbps doesn't work. Version 0.4: 1.
