============================ R E L E A S E N O T E S ============================ Broadcom Gigabity Ethernet Driver For Windows 2000 and Windows NT 4.0. Copyright (c) 2000 Broadcom Corporation All rights reserved. Version Release Date ======= ============ 1.15 11/26/00 Fixed intermitten system lock-up on shutdown when WOL is enabled. Multicast table was never cleared which was causing the intermitten failure in 2c_rmult. 5401 reset on link down should occur only when the current speed is 1gb. Reduced driver load/unload time which will eliminate the 1c_gtime warnings. However, these warnings may still occur when WOL is enabled. This is due to the driver waiting for auto-negotiation to complete before completing initialization. 1.14 11/22/00 Added a software workaround for the 5401 to prevent it from locking up when the cable is unplugged during transmission. All the LEDs now indicate their corresponding link speed. 1.13 11/21/00 Fixed problem with TCP connections dropping when running Chariot in 10/100mb mode. Fixed problem with the adapter being disabled after exiting from the standby mode in Windows 2000. Fixed problem with the adapter not entering into wake-up mode when "shutdown". Ignore TX checksum parameter for B0 silicon. 1.12 11/18/00 Added WOL support for Windows 2000. Fixed intermitten lock-up in 10mb mode. Shadowed several MAC registers. Fixed PHY register read problem. Occasionally PHY register read returned an incorrect value. Default TaskOffload and FlowControl parameter to off. 0.9 11/10/00 Added MagicPacket support. In v0.8, whenever the driver detects a link mismatch, it will recover by switching to auto-negotiation mode. This version does not have this recovery mechanism. Write the link settings to the EventLog after the driver has initialized. Fixed 1c_gtime failure when forcing line speed. 0.8 11/03/00 NdisPacket allocated by the driver did not have the protocol reserved area which could cause system crash. Added a better handshaking mechanism with the firmware. Fixed the 2m_addres test. Added Compaq Hot Plug PCI support in oemsetup.inf. The MAC was not properly setup to operate in half duplex mode. Modified the driver to receive maximum sized VLAN packet without using the Jumbo receive ring. 0.7 10/30/00 Fixed problems with forcing line speed. Added checksum offloading capability. Fixed several issues with the Ndis test. The following test should pass now: 1c_ofldn, 2m_load, 2m_misc, 2m_addre. Added support for IBM hot plug. 0.6 10/22/00 Fixed lock-up that occurs when running the Ndis stress test. Fixed system crash when stopping the driver on an A1 silicon. Minor changes in b57nt4.hlp. Fixed problems with PHY loopback. Added support for MAC loopback. Added a vendor specific OID for changing the MAC address. Tested VLAN tagging and 802.1p priority packet. 0.5 10/17/00 Added a timer routine to periodically program the hardware to update the status block and generate an interrupt. This is necessary because with A0, A1, B0 silicon, under certain condition, the host will miss interrupts. Disable PCI NWI by default. The send producer index is written twice. This is a bug in the A0, A1, B0 silicon in which chip will miss the mailbox stimulus. Added tx/rx PAUSE frame negotiation with link partner. Modified b57w2k.inf to allow the user to configure rx/tx PAUSE frame independently. Fixed VLAN bug. The driver was retrieving VLAN tag from the wrong offset in the miniport reserved area. Added jumbo frame support. The user must manually modify the registry parameter to enable this feature. "RxJumboDescCnt" must be changed to some value greater than 20 but less than 256. This value determine the numbe of receive buffers to allocate for jumbo frames. Modified oemsetup.inf and b57w2k.inf to default "DisableAutoNeg" to 1, which will disable auto-negotiation advertisement when selecting a particular line speed. Added a help file for b57nt4.sys driver. 0.04 10/02/00 Added support for link change detection via PHY interrupt as oppose to having the MAC poll the PHY. PHY interrupt processing can be enable via "UsePhyInterrupt" registry parameter. Default is "auto-polling". Miscellaneous modifications oemsetup.inf and b57w2k.inf. Also fixed driver update issues with oemsetup.inf. Added delay before the driver is unloaded to prevent W2K from detecting the card as a different device. Fixed the deserialized driver to queue outgoing packets when there is no more packet descriptors left. 0.03 09/21/00 Modified reset and halt routines to handle shutdown more robustly. Some systems will not recognize the board after a warm boot. This version of the driver should fix this. 0.02 09/09/00 Initial release for the A1 silicon.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.
