Appendix J: Updating BIOS Code

The following information details the steps necessary to update BIOS code.

Procedure

To update the BIOS code using tftp/ip, perform the following steps:

  1. Enable tftp in the /etc/inetd.conf file.
  2. Connect the physical interface.
  3. Configure the logical device interface. This interface must be in the UP state.
  4. Establish a BIOS console session.
  5. Issue the admin command to enter password privilege mode.
  6. Issue the set inet XX.XX.XX.XX command to set the IP address of the 7318.
  7. Issue the set loadi /usr/lib/cns/bios command to select the bios image to load.
  8. Issue the set host1 XX.XX.XX.XX command to select the host to download from.
  9. Issue the set frametype ethernet_ii command to select the correct frametype. Substitute ethernet_SNAP if the Ethernet Version II is not configured for the host.
  10. Issue the set gateway XX.XX.XX.XX command, if necessary, to reach the load host selected in step 5 above.
  11. Issue the set netmask X.X.X.X command, if necessary, to set the correct subnet mask.
  12. Issue the biosload command to start the process. At the prompt, select y to reprogram the BIOS image if it is the desired image. The 7318 will automatically reboot.

To update the BIOS code using tftp/ipx, performing the following steps:

  1. Configure the 7318.
  2. Configure IPX. IPX must be running.
  3. Configure the physical interface.
  4. Configure the logical device interface. This interface must be in the UP state.
  5. Run the cnsview daemon.
  6. Establish a BIOS console session.
  7. Issue the admin command to enter password privilege mode.
  8. Issue the set inet XX.XX.XX.XX command to set the IP address of the 7318.
  9. Issue the set loadi /usr/lib/cns/bios command to select the bios image to load.
  10. Issue the set host1 XX.XX.XX.XX command to select the host to download from.
  11. Issue the set frametype ethernet_ii command to select the correct frametype. Substitute ethernet_SNAP if the Ethernet Version II is not configured for the host.
  12. Issue the biosload command to start the process. At the prompt, select y to reprogram the BIOS image if it is the desired image. The 7318 will automatically reboot.

Example

The following trace shows an example of an actual BIOS upgrade. Notice that the TFTP was failing at first. The TFTP entry in the /etc/inetd.conf file needed to be uncommented and refresh -s inetd issued. Shortly after this was done, the data transfer was successful.

#> set inet 2.2.2.99
ok
#> set loadi /usr/lib/cns/bios
ok
#> set host1 2.2.2.1
ok
#> set frametype=ethernet_ii
ok
#> set netmask=255.255.255.0
ok
#> biosload
