6)-4. MAC ADDRESS&FIRM write UTILITY
Operation
This utility writes the MAC address and firmware.
(Procedure)
Install the master EPROM on the TCP/IP board and turn the IPL
switch on the board to the "program write mode."
Turn on the ECR.
The IPL program on the TCP/IP board starts.
Input 3 sets of 3-digit decimal numbers through the keyboard of
the ECR and press the ENTER key.
Following the SHARP maker code (08, 00, 1F), the 3 sets of
numbers input through the keyboard are converted into hexadeci-
mal numbers. The program then writes a total of 6 bytes of MAC
address into dual port RAM (800000H - ).
Turn off the power supply.
Remove the EPROM from the TCP/IP board and turn the IPL
switch to the "normal mode."
