Broadcom Corporation 16215 Alton Parkway, Irvine, CA 92619-7013 Installation Notes Broadcom BCM5700 SCO Unixware 7/Caldera Open Unix 8 driver Introduction ============ This file describes the SCO Unixware 7/Caldera Open Unix 8 driver for the Broadcom NetXtreme BCM5700 series 10/100/1000 Mbps Ethernet Network Interface Controller. Driver Software Package ======================= The driver is released as an installable package in datastream format. Installing Driver ================= Do the following to install the bcme package on the Unixware system: pkgadd -d <install_path> where <install_path> is the full path name of the installable package bcme-<version>.pkg. After the package is installed, use netcfg or scoadmin network to add the new network adapter. When prompted, choose the line speed and select Advanced option for Flow Control and MAC Address settings if desired. The different settings of these parameters are listed below: Line Speed: Auto Negotiation (default) (all speeds advertised) 10 Mbps half duplex fixed 10 Mbps half duplex auto (only 10 Mbps half duplex advertised) 10 Mbps full duplex fixed 10 Mbps full duplex auto (only 10 Mbps full duplex advertised) 100 Mbps half duplex fixed 100 Mbps half duplex auto (only 100 Mbps half duplex advertised) 100 Mbps full duplex fixed 100 Mbps full duplex auto (only 100 Mbps full duplex advertised) 1000 Mbps half duplex auto (only 1000 Mbps half duplex advertised) 1000 Mbps full duplex fixed* 1000 Mbps full duplex auto (only 1000 Mbps full duplex advertised) Flow Control: Auto Negotiation** (Symmetric Pause advertised) (default) Disabled Receive Pause Transmit Pause Receive & Transmit Pause MAC Address: No Override (default) a user administered MAC address entered with a colon separating each hexadecimal byte, e.g. 12:34:56:78:9a:bc Jumbo MTU Size: 1500 - 9000 (default is 1500) Wirespeed: Enabled *** Disabled (default) *Note that 1000 Mbps (1Gbps) full duplex fixed speed is only valid for fibre connections. For copper twisted pair connections, 1 Gbps can only be set through auto negotiation with a 1 Gbps link partner. **Note that auto negotiation of flow control is only valid when the line speed is set to auto negotiation (all speeds or single speed advertisments). *** Ethernet@wirespeed allows the hardware to attempt to work with broken ethernet cables. It is not recommended that this option be used when configuring interfaces in team. After the parameters are selected, select network protocol and address when prompted. Advanced Tunable Parameters =========================== Advanced tunable parameters for the BCM5700 are located in the file /etc/conf/pack.d/bcme/space.c. Changing these parameters can affect the performance of the driver. See the bcme man page for details. Disabling ASF in the firmware ============================== This driver does not support ASF. If you find that the driver does not load due to ASF being enabled in the firmware, use the following procedure to disable it: 1. Download the BCM57xx User diagnostic from our driver download site at : http://www.broadcom.com/drivers/downloaddrivers.php 2. Create a DOS bootable floppy 3. Unpack the diag zip-file into this floppy 4. Boot to DOS using this floppy 5. Enter "b57udiag -cmd" 6. Enter setasf -d 7. Reboot the system Unexpected WARNING messages =========================== This driver contains a new feature that allows the linkspeed, as reported by ndstat, to be updated as the link conditions change. Unfortunately, this feature also produces a lot of warning messages on older UnixWare installations. If you see the following warning message, you will need to update your installation : WARNING : mdi_primitive_handler - Unexpected message from MDI driver(bcme), primitive = 0x17 To get rid of these messages, download and install Maintenance Pack 2 from SCO's website.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.
