Well, originally you got an adaptor with the unit and had to stick one of the Kicstart ROMs in it... translated from the manual... Be warned, the markings on A3000 motherboards may bear no relationship to what you have fitted. You want to pay attention to which end the notches are on chips before you start levering them out. They can be very tricky.
Locate the SCSI chip on the main board of your Amiga
3000. It bears the inscription WD33C93, Has a 40-pin DIL (dual-in-Line) housing and is located in the back of the computer
.
Now locate the kickstart ROMs. They are immediately there Next to the mouse and joystick connectors.
Now install the adapter sockets that are included with your Apollo 3040/3060 card. Leverage the SCSI chip WD33C93 Carefully with a wide screwdriver from its Base and insert it into the 'two - storey' base, which is the
inscription WD33C93 wearing. Make sure that the Marking notches of socket and SCSI chip.
Now carefully crank a Kickstart ROM (no matter which) Its base and
Plug it into the other socket, using the Kickstart ROM Is labeled. Now place the adapter bases with the chips in theCorresponding base on the main board. Pay attention to the correct polarity.
If you have purchased the Apollo 3040/3060 card with SCSI option to run SCSI devices,
Cable. Ensure correct polarity. Pin 1 of the cable is marked red, on the Apollo 3040/3060 board is a '1'.
Check again the position of the jumper 'SCSI', Which determines the Autoboot / Automount function.
Insert the drive carrier and turn back the screws (3 front, 2 rear).
If necessary, install your Zorro 2/3 expansion cards.
Close the housing cover, secure it with the screws provided and attach the cables to back to the computer housing
Perform a test run to ensure that everything is installed correctly. If your computer pauses while booting, check to see if The
68040.libraryFrom the Apollo Install disk to your boot partition.
If everything works as expected, you are done with the installation and are now owner (in) one of the fastest Amiga systems.
If your system does not start as expected, please refer to chapter 9...
... I think I get why. Getting an A3000 to boot from a different controller is no easy task. So I'm guessing the SCSI chip has to send a "go" signal to the ROM chips, otherwise the processor can't access the ROMs to begin working. If the first boot device is on the SCSI chain connected to an accelerator, that complicates matters. Plenty of people report complete failure with not having at least one SCSI device connected to an A3000 onboard SCSI controller. It is a minefield area.
Issue might date back to the first A3000s, and the fact they loaded KS from Harddisk... so you NEEDED at least one drive connected to the onboard SCSI for the kickstart file.
If I was to pick ONE pin on the ROM... it would be chip select. That seems sensible, it's the basic "Go chip, do your business" signal. Pins 10 and 12 (maybe both) are candidates, but you should really consult a datasheet on an ROM chip of that type if you haven't already.
The other end, the SCSI chip, I'm not so sure of. Maybe SCSI select, I think that's active low... You are have to be very careful experimenting with this stuff. You want to make sure the connections aren't going to slip and short out while you are busy turning computers on and off. Pin 39 is /REQ. Same deal, you have to check the datasheet of the chip.
