Once the memory has been installed and the jumpers have been reset, you
need to change the EEPROM locations for memory installed and memory tested.
To access EEPROM memory locations:

	1) perform a gracefull shutdown.
	2) at the monitor(>) prompt
	   >q 14 <ret>
	   EEPROM 014: 04?	-- system returns with 4MB installed
	3) at the prompt enter the hex value that matches the total
	   memory installed in the system:
	   EEPROM 014: 04? 10 <ret>  -- for 8 MB installed.
	   EEPROM 015: 04> 10 <space bar> <ret>  -- memory tested during bootup.
	   > (the space bar & return) takes you back to the monitor
	   prompt.

You can go through the process again to verify the changes made.  Finally,
power down.  Then turn power on and reboot. Good Luck!
