SCO OpenServer Release 6.0.0 new features and notes

Hardware support

SCO OpenServer Release 6.0.0 includes new and updated hardware support.

USB support

The SCO OpenServer Release 6.0.0 USB subsystem includes USB 2.0 support for EHCI Host Controllers and USB 1.1 support of OHCI and UHCI Host Controllers. Supported USB devices include keyboards, pointing devices, CD-ROM drives (including bootable drives), floppy drives, mass storage devices, and printers.

For information on how to connect USB devices, see the usb(HW) manual page.

Note the following:

For more information on the SCO OpenServer Release 6.0.0 USB subsystem, see the usb(HW), usblp(HW), and usbprobe(ADM) manual pages.

Video adapter support

SCO OpenServer Release 6.0.0 includes new and updated support for a wide variety of video adapters, including AGP and PCI Express cards. For a list of supported cards, see ``Supported video adapters''.

NOTE: The SiS (Silicon Integrated Systems) SIS661FX chipset should not be used as it can cause the system to panic.

In most cases, SCO OpenServer can automatically detect and configure your video hardware. For information on video adapter configuration, see ``Configuring video adapters'' and the xorg.conf(4) manual page.

NOTE: Depending on the video adapter that you are using, you may encounter some problems with automatic configuration. For example, testing has revealed problems with the Virge3dx video adapter where the configuration settings that are made automatically do not work. If you experience problems of this kind, see ``Configuring video adapters manually'' for more information.

Network card support

Network card support in SCO OpenServer Release 6.0.0 has been updated as follows:

Intel PRO/100 (eeE8) notes

If you are using an Intel PRO/100 NIC and you see a message similar to:

   WARNING: eeE8: eeE8ValidateChecksum: EEPROM checksum validation failed (slot6,port1)

you may have a failed network adapter that needs to be replaced.

Note that checksum validation is enabled in this driver. If you want to disable this check:

  1. Edit the /etc/conf/pack.d/eeE8/space.c file.

  2. Locate the uchar_t eeE8_validate_eeprom_en entry and change the value from ``1'' to ``0''.

  3. Run /etc/conf/bin/idbuild -B.

  4. Run init 6.

It is also a good idea to make the same changes to the /etc/inst/nd/mdi/eeE8/Space.c file in case you reconfigure the eeE8 driver using the Network Configuration Manager.

PC Card support

SCO OpenServer Release 6.0.0 supports the following new PC Card adapters, including CardBus NICs and selected PRISM II-based Wireless PC Card NICs:

ISA and EISA network card support

ISA and EISA network card device drivers contained in SCO OpenServer Release 6.0.0 are provided to SCO customers as-is. No warranty or SCO support of any kind is provided for these devices. ISA and EISA network card devices from UnixWare 7.1.3 and 7.1.4 should work on SCO OpenServer Release 6.0.0 but have not been tested. A listing of these devices can be viewed in the SCO Hardware Database, which can be viewed at:

In future releases, ISA and EISA network device drivers will be removed from the product as these devices are no longer available, nor can they be used in computer systems certified for SCO OpenServer Release 6.0.0.

Configuring a backup network card

If a network adapter's hardware allows its Media Access Control (MAC) address to be reprogrammed, you can configure the adapter as a ``backup'' device for an existing primary NIC. If the primary device fails or it loses its physical connection, the system automatically switches to using the backup device. This functionality is commonly referred to as ``device failover''.

NOTE: Automatic failover requires that the primary device's driver is capable of recognizing and signaling such problems to the kernel. Some device drivers may be capable of detecting hardware failure but may be unable to tell if the physical connection has been broken.

You may only configure a backup device after you have configured the primary device. When configuring a backup device, you are asked to select the primary device that it will support.

One backup device may be configured for each primary device.

To add an adapter as a backup device, run the Network Configuration Manager. Select Hardware -> Add new LAN adapter -> . On the Add Protocol screen, select Backup Device instead of a protocol suite such as TCP/IP. Then select an existing network adapter (the primary device) for which the new adapter will act as a backup device and click on OK.

The Network Configuration Manager indicates that a primary device has failed or is otherwise unavailable for use by placing a cross on the icon for the network adapter. (In character mode, the string ``HX'' replaces ``HW''.)

Some packets may be lost when the system switches to a backup device. Retransmission of packets happens automatically in the case of TCP/IP connections. However, not all applications that use UDP may be capable of handling such interruption of service gracefully.

NOTE: Currently, you cannot use the Network Configuration Manager to switch between primary and backup devices manually. The Hardware -> Switch to Backup and Hardware -> Revert to Primary menu options do not work.
