Driver Installation - for SCO UNIX MDI Driver ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (1) Introduction: ----------------- This Readme file explains how to install the SCO Unix MDI driver. The Preinstallation Hardware and Software Requirements: a) Firmware Requirements: o Fully complient Rev. 2.0 or above PCI BIOS supplied with the PC. o If Ethernet adapter makes use of Digital Semiconductor 21050 (PCI-PCI bridge) or any other PCI-PCI bridge, the PCI BIOS should support PCI-PCI bridge architecture. b) Software Revision Requirements: o OpenServer or higher version o SCO AHS This directories contains the following files: SUM332TD.Z (28669) The compressed image of the distribution diskette. The distribution diskette contains all the files required for installing the driver using custom and netconfig, in particular: - custom related scripts. - netconfig related scripts and AOF files. - Driver.o, the driver - Space.c, the parameter file - space.h - header file, not intended to be modified (2). Driver Installation: ------------------------- To install the SCO Unix MDI Device Driver: 1. Copy the file SUM332TD.Z to SUM332T.dd.Z on a SCO Unix machine. The number in parentheses near the file's name (above) is the checksum for the file. To verify, use: sum -r SUM332T.dd.Z and compare the results. 2. Uncompress SUM332T.dd.Z to SUM332T.dd, using: uncompress SUM332T.dd 3. Copy the file to a diskette. To create a 3.5" floppy in drive 0, use: dd if=SUM332T.dd of=/dev/rfd0135ds18 Mark the diskette: DC21X4 PCI Ethernet Adapter MDI driver Rel.03.32 4. Run custom. From the menu select: Software -> Install New -> From Host -> Media Floppy -> Full 5. Put the distribution diskette in the drive and select continue. 6. When prompted for distribution floppy 1, just press enter. 7. When custom has completed, remove the diskette and quit custom. 8. Run netconfig. Add the desired chain. The DC21X4 drivers are called: "Digital DC2104X PCI Ethernet controller" and "Digital DC2114X PCI Ethernet and Fast Ethernet controller" NOTE: For boards with more than one Digital Semiconductor 21X4X on them, a driver must be installed for each active port on the board. Thus, if a board has two separate ports, two separate chains must be created in order to connect both ports to networks. This is similar to installing two boards, each with one port. Not all ports must be active. 9. You can change the default value of the media by using the "Advanced Options..." option in the menu. 10. When the chain has been configured, select "Exit" from the netconfig menu. If you don't wish to modify the space.c file relink the kernel at the prompt. 11. If you wish to change parameters in the space.c file, edit /etc/conf/pack.d/d21x/space.c and make the required changes. The changes will apply to all the installed boards. 12. To activate the adapter, you must reboot. When the system boots, you should see the following message among the other configuration messages: %d21x 0x2000-0x2200 5 - type=DC21040/TP addr=12-34-56-78-9a-bc or %d21x 0x2000-0x2200 5 - type=DC21140/100TX addr=12-34-56-78-9a-bc with the appropriate I/O addresses, IRQ, serial media and IEEE address. (3). Parameters: ----------------- The space.c file contains the different parameters that can be modified. They can be divided into several groups: 1. Port parameters. These include: XXX_BUS_ARBITRATION XXX_BURST_LENGTH XXX_CACHE_ALIGNMENT XXX_PASS_BAD_FRAMES XXX_BACKOFF_CNTR XXX_10MB_THRESHOLD XXX_100MB_THRESHOLD XXX_PARITY_ERROR_RESPONSE XXX_LATENCY_TIMER XXX_CRC_CALC XXX_DC2114X_GPR_CTRL XXX_DC2114X_GPR_DATA XXX_TURBO XXX_SNOOZE XXX_0_MAC_ADDR XXX_1_MAC_ADDR XXX_2_MAC_ADDR XXX_3_MAC_ADDR 2. Driver tuning parameters: XXX_RX_BUFS_TO_POST 3. Driver diagnostics control: XXX_DEBUG The meaning of each is explained in detail in the space.c file, including allowed values for each parameter. The values in space.c apply to ALL the installed boards, except the MAC address parameter. Space.c is NOT the place to modify the board's slot number line. This must be modified in netconfig, by running the reconfiguration script. The serial mode interface can be changed during netconfig as explained before. (4). Errors and trouble shooting: ---------------------------------- 1. Mismatch between PCI configuration and netconfig/space.c: In order for the adapter to work correctly, the same values that are used during the PCI configuration (e.g CFLT) must be used in the space.c file. Mismatches may cause the adapter to malfunction, or even hang the system. Currently, the PCI setup takes precedence except for the value for the latency timer, which is taken from the space.c file. (5). Driver's error messages (when working in debug level > 0): ---------------------------------------------------------------- In "d21xi" the 'i' stands for a number between 0 and 3, indicating the particular instance of the driver the message is reported by. * "d21xi Could not intialize driver, PCI BIOS couldn't read/write configuration register" This message will be printed in PCI board - if can't read or write the configuration registers when using the PCI BIOS. * "d21xi Could not intialize driver, found PCMC revision.1 with write-back cache mode" This message will be printed in PCI board - if PCMC rev.1 chip was found and it works with write-back cache mode (this mode can cause crash in the driver). * "d21xi Could not intialize driver, unsupported PCI board - DC21040 revision.1" This message will be printed in PCI board - if it is a board with Digital Semiconductor 21040 revision 1 on it. * "d21xi Could not intialize driver, unsupported board - DC21140 revision 1.0" This message will be printed if the board has Digital Semiconductor 21140 revision 1 on it. * "d21xi Could not intialize driver, unsupported Digital Semiconductor" This message will be printed if the board doesn't have one of the following Digital Semiconductor on it: -DC21040 -DC21140 -DC21140A -DC21041 -DC21142 -DC21143 * "d21xi Could not intialize driver, couldn't link interrupt handler to interrupt line" This message will be printed if the driver couldn't link the interrupt line to the interrupt handler. * "d21xi Could not intialize driver, unsupported interrupt line was set by the PCI BIOS to CFIT" This message will be printed in PCI board - if the value of the interrupt line that was read from the CFLT register > 0xF * "d21xi Could not intialize driver, unsupported selected serial media" This message will be printed in boards with Digital Semiconductor 21041 or 21140 or 21140A or DC21142 or DC21143 - if unsupported serial mode was choose by the user or read from the SROM (in case the user choose to use the SROM value) for the serial interface of Digital Semiconductor 21041 or 21140 or 21140A or DC21142 or DC21143.

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.
