Upgrading Cache Memory
Step Action
1 Turn the system off. If the motherboard is already installed in a
computer case, remove the cover and expose the motherboard.
2 Make sure you are properly grounded to prevent electrostatic
discharge.
3 Install the new 32 KB x 8 5V SRAM DIPs in sockets U27, U30,
U35, and U38. Make sure that Pin 1 of the sockets matches Pin 1
of the SRAM DIPs.
4 Place a shorting brideg (Jumper) on Pins 2-3 on J42, J44, and J45
on the motherboard.
5 Reinstall the motherboard and turn system power on.
6 The system BIOS should report 256 KB of secondary cache
memory now after the computer boots. If it does not, repeat the
cache memory installation procedure above.
