the actual microcode download using the "copy"-command. Otherwise the printer drivers may interfere in the microcode image sent to the PrintServer implying serious problems.

You should use a generic/text printer driver when running Windows environment and IBM NULL when running in OS/2.

5.Pay attention to the LED's on the PrintServer rear panel. These will now blink very quickly - one after the other. This is an indication of the microcode download taking place.

6.After the download process (time will depend on the PC’s hardware) the “PAR” LED will stay lit. The remaining LEDs will be off.

7.Your PrintServer has now been equipped with a new microcode.

8.Power the PrintServer printer off and back on for the new microcode to become effective.

Press the test key in order to verify the new microcode level stated on the test printout page.

See section 3.3.8 for details on this.

Appendix C.3 Upgrading Microcode via TCP/IP Boot Server

The microcode can be downloaded to the PrintServer using the TCP/IP protocol TFTP:

1.Customising the BOOTP server data base access file (BOOTPTAB file entry for the device with a bootfile parameter).

2.Customising the bootfile entry (customising the bootfil e to indicate the path to the microcode).

3.Power the printer off/on.

4.Validate the update microcode.
