- When I was confronted with the prospect of upgrading my Amiga 3000
- to Workbench 3.1 I assumed that it would come with a means to update
- my softboot kickstart, perhaps a new SuperKickstart disk. When such was
- not the case I was disappointed.
-
- Some of the flexibility I enjoyed would be lost. To rectify that situation,
- I started tinkering. Then something wonderful happened.
-
- I take no responsibility for damage resulting from the (mis)application
- of the following information. It worked for me.
-
-
- INSTALLING SOFTBOOT KICKSTART 3.1 ON AN AMIGA 3000
-
-
- PREPARATION:
-
- Read through this entire procedure.
- Purchase the 3.1 upgrade kit for Amiga 3000 (T).
- Backup your WB_2.x: partition.
- Go into preferences and document important items to paper or image capture
- -printer settings, -palette settings, -pointer image etc.
- Go into WB_2.x:prefs/env-archive/sys and delete all files in that drawer.
-
-
- KICKSTART ROM:
-
- Install the new ROMs in the same location as your existing softboot ROMs.
-
- If your ROMs are currently installed on the motherboard that is where the
- new ones go.
-
- If your ROMs are currently installed on a tower adapter (an upside down
- circuit board rearward of the keyboard connector) some ambiguity presents
- itself. The tower has four sockets, one labeled U181, one labeled U180,
- the motherboard has four sockets, one labeled U181 and one labeled U180.
- Your new 3.1 ROMs go in the tower, not the motherboard. Mark the tower
- orientation with respect to the motherboard. (Put an arrow on the tower
- board pointing to a conspicuous motherboard landmark.) Remove the tower
- and mark the pin 1 end of the U181 and U180 sockets. Install the new ROMs.
-
- When you power up your system three things may happen.
- 1) It's alive! Continue to the next stage.
- 2) Nothing happens. Swap the 3.1 ROMs.
- 3) Nothing happens and the acrid odor of burned chips fills your nostrils.
- -Shut down power. The ROMs fried. Take a break.
- The ROMs were installed backwards. No second chance.
- Carefully put your softboot ROMs back where they were.
-
-
- MAKE 3.1 SOFTKICK KICKSTART
-
- Obtain GrabKick, it's on Fish831. Save your kickstart 3.1 ROM code to a
- file called t:kickstart3.1. From an AmigaDos shell:
-
- grabkick t:kickstart3.1
-
- Edit WB_2.x:devs/kickstart with an editor that can operate on binary files.
- I used CygnusEd. Cut the first 1024 blocks from the file and save as
- t:oldkickstart_rom_image. The remainder of the file save as t:bonus20.
-
- Compare file sizes. Both t:kickstart3.1 and t:oldkickstart_rom_image should
- be 524288 bytes long. If not, repeat step 2 until the correct file sizes
- are obtained and all the numbers add up.
-
- The purpose of the previous two steps is to extract bonus20 correctly.
- bonus20 is a trailer to the kickstart ROM image that makes it understood by
- your Amiga 3000 as a softkick kickstart.
-
- Append bonus20 to the kickstart 3.1 ROM image. Use your editor or from an
- AmigaDos shell:
-
- join t:kickstart3.1 t:bonus20 as WB_2.x:devs/kickstart.
-
- At this point your softkick kickstart file has been updated to 3.1.
-
-
- RESTORE SOFTKICK ROM
-
- Reverse the 3.1 ROM installation procedure to restore your system to its
- original hardware configuration.
-
- Put your 3.1 ROMs away for safe keeping.
-
- When your system boots up "Loading Kickstart 2.x" it is actually loading
- Kickstart 3.1.
-
-
- INSTALL WORKBENCH 3.1
-
- Self explanatory.
