Appendix J: Updating 7318 BIOS Code

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


To update the BIOS code, perform the following steps:

  1. Establish a BIOS console session.
  2. Issue the admin command to enter password priviledge mode.
  3. Issue the set inet XX.XX.XX.XX command to set the IP address of the 7318.
  4. Issue the set loadi /usr/lib/cns/bios command to select the BIOS image to load.
  5. Issue the set host1 XX.XX.XX.XX command to select the host to download from.
  6. Issue the set frametype ethernet_ii command to select the correct frame type. Substitute ethernet_SNAP if Ethernet Version II is not configured for the host.
  7. Issue the set gateway XX.XX.XX.XX command, if necessary, to reach the load host selected in step 5.
  8. Issue the set netmask X.X.X.X command, if necessary, to set the correct subnet mask.


The following trace shows an example of an actual BIOS upgrade. Notice that the Trivial File Transfer Protocol (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.
