This section contains procedures for installing Broadcom NetXtreme™ Gigabit Ethernet Adapter drivers for SCO OpenServer 5.0.6 and UnixWare 7 and includes the following information:

SCO Open Server

UnixWare/OpenUnix 8

SCO OpenServer 5.0.6

Overview

This procedure describes the installation of the SCO OpenServer driver. This driver is released as a media image file containing the driver package. The media image file can be copied to the target machine directly for installation, or from an installation diskette that you can create.

Creating a Diskette

1. Copy the file VOL.000.000 to an SCO system.
2. Create a diskette using: dd if =VOL.000.000 of=/dev/rfd0135ds18.

Installing the Driver

1. Use custom or scoadmin software to install the SCO OpenServer driver from the media image or from the floppy created above.
2. After the package is installed, use netconfig to add the new network adapter.
3. Once added, modify the hardware configuration in Advanced Options to change the Line Speed and Flow Control if desired. The settings for these parameters are listed below:

Line Speed

• AutoNegotiate (default) (all speeds advertised)
• Fixed HalfDuplex10
• Auto HalfDuplex10 (only 10 Mbps half duplex advertised)
• Fixed FullDuplex10
• Auto FullDuplex10 (only 10 Mbps full duplex advertised)
• Fixed HalfDuplex100
• Auto HalfDuplex100 (only 100 Mbps half duplex advertised)
• Fixed FullDuplex100
• Auto FullDuplex100 (only 100 Mbps full duplex advertised)
• Auto HalfDuplex1000 (only 1000 Mbps half duplex advertised)
• Fixed FullDuplex1000 (Note 1)
• Auto FullDuplex1000 (only 1000 Mbps full duplex advertised)
  

NOTE 1 – 1000 Mbps (1 Gbps) full duplex fixed speed is only valid for fiber connections. For copper, twisted-pair connections, 1 Gbps can only be set through autonegotiation with a 1 Gbps partner.

Flow Control

• Off (default)
• AutoNegotiate (Symmetric Pause advertised) (Note 2)
• RxPause
• TxPause
• RxPause/TxPause

NOTE 2 – Autonegotiation of Flow Control is only valid when the Line Speed is set to AutoNegotiate (all speeds advertised or single speed advertised).

NOTE 3 – A kernel relink and reboot is required before the new configuration will take effect.

Jumbo Frames and Other Advanced Parameters

Jumbo MTU sizes and other advanced, tunable parameters for the BCM5700 controller are located in the file space.c in the directory /etc/conf/pack.d/bcme. A description for each parameter is contained in space.c. Modify the desired parameter in space.c, rebuild the kernel by doing /etc/conf/bin/idbuild and rebooting the system. Note that the MTU sizes can be individually set for each adapter in the system, whereas all other parameters apply globally to all adapters.

UnixWare/OpenUnix 8

Overview

This procedure describes the installation procedure for the UnixWare driver. The driver is released as an installable package in datastream format.

Installing the Driver

1. 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.
   
2. After the package is installed, use netcfg or scoadmin network to add the new network adapter.
3. When prompted, select the Line Speed and then select Advanced Option for Flow Control, MAC Address , and Jumbo MTU Size settings, if desired. The settings for these parameters are listed below:

Line Speed

• AutoNegotiate (default) (all speeds advertised)
• 10 Mbps HalfDuplex Fixed
• 10 Mbps HalfDuplex Auto (only 10 Mbps half duplex advertised)
• 10 Mbps FullDuplex Fixed
• 10 Mbps FullDuplex Auto (only 10 Mbps full duplex advertised)
• 100 Mbps HalfDuplex Fixed
• 100 Mbps HalfDuplex Auto (only 100 Mbps half duplex advertised)
• 100 Mbps FullDuplex Fixed
• 100 Mbps FullDuplex Auto (only 100 Mbps full duplex advertised)
• 1000 Mbps HalfDuplex Auto (only 1000 Mbps half duplex advertised)
• 1000 Mbps FullDuplex Fixed (Note 1)
• 1000 Mbps FullDuplex Auto (only 1000 Mbps full duplex advertised)

NOTE 1 – 1000 Mbps (1 Gbps) full duplex, fixed speed is only valid for fiber connections. For copper, twisted-pair connections, 1 Gbps can only be set through autonegotiation with a 1 Gbps link partner.

Flow Control

• Disabled (default)
• Auto Negotiation (Symmetric Pause advertised) (Note 2)
  
• Receive Pause
  
• Transmit Pause
  
• Receive & Transmit Pause

NOTE 2 – Autonegotiation of Flow Control is only valid when the Line Speed is set to Auto Negotiation (all speeds advertised or single speed advertised).

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)
