Installation Instructions for Amiga 2000
If you have no prior experience with installations of computer components or if you feel
uncomfortable with doing the installation yourself, please let an authorized Amiga dealer perform the
upgrade for you. Neither Amiga Internationa?, Inc. nor Vesalia Computer will be responsible or liable
for any damages caused by improper installation of the 3.1 ROM chip.
Before any internal expansion is installed, the system must be turned off and disconnected from the power
supply. All cables for external peripherals should be disconnected from the system. To avoid damages by
discharge of static electricity, please touch a grounded metal surface before you begin with the installation
of the 3.1 ROM chip.
Then proceed as follows:
■ Remove the five screws that secure the case (two on each side, one on the backside) and remove the
housing lid by pulling it towards the front side.
■ The floppy drive(s) and the power supply have to be removed together with their attachments. Remove
the screws that secure the mounting support (up to seven depending on the model) and disconnect the
cables (please note their alignment). Lift the complete unit and put it aside.
■ The Kickstart ROM is situated on socket 11500, on the right hand side of the processor MC68000.
Depending on the version of the Kickstart ROM, it carries one of the following labels:
1.2:
315093-01
1.3:
315093-02
2.04: 390979-01 (37.175)
Use a suitable tool (e.g. screwdriver) to remove the ROM chip from its socket. Please note the alignment
of the chip.
■ Depending on the revision of the mainboard, there are different steps to take. The revision is printed on
the frontmost left corner of the board. If it reads
© 1989 Commodore, AMIGA 2000, MADE IN GERMANY (BSW)
and the mark on the ROM chip/socket is pointing towards the front, then you have to solder a connection
from pin 1 to pin 31 of the ROM chip. This step is not necessary fcr any other board revision (print reads
B2000-CR, ROM chip/socket mark pointing to the backside).
■ Now the Kickstart 3.1 ROM chip can be put into place. The alignment of the chip is most important,
please make absolutely sure that the marks of the chip and the socket match, both notches must be on the
same side. When done, press the ROM chip firmly into place, be cautious not to bend pins.
Warning: Failure to align the ROM chip correctly will destroy it!
The installation is complete. You can reassemble your Amiga 2000 now.
