A500 Rev6A Board and Kickstart 3.1
« on: June 24, 2003, 09:04:44 PM »
Hi Folks,

I am an old Amiga user, but I was never into hardware.

I have a A500 with Rev6A board. I am trying to install a kickstart ROM from my old A2000, 3.1 40.68. When installed, A500 won't boot, it gives a Software Failure error (red blinking), if you hit left mouse button, screen goes to black.

If I reinstall the original 1.3 ROM, all is fine. The 3.1 ROM is ok on A2000 as well.

Any suggestions? To my knowledge it should work without any problems, am I misinformed?

TIA,

PalMop

All the pins are in without any problems and the chip works still fine in A2000. When I insert 1.3 ROM, it works, even if it is not inserted to the socket fully (all legs of course in the sockets), so I doubt it is a contact issue.

On a side note, I had another ROM, sent by the original owner of A500 (I got it from Ebay), and that didn't work at the time, but I didn't bother, as 1.3 was fine. I don't know where the chip is now, so I can't test it on A2000 now, but there is a chance something else is causing the issue.

The A500 has a memory expansion to 1Mb. Should I remove and try that?

Well, I am not expert, but on the right side of the board it clearly says REV6A, that's where I got the info from.

I won't be into work for two days, but I can send a pic on Friday.

As far as I can see there is no jumper wires on the ROM (I'll double check on Friday), I thought the jumper was only needed for old motherboards, like Rev5

The rom is clean, I can't see any wires on it... Any other ideas?

Yup, it says 40.68.





and it was inserted properly, with the curved ends matching (otherwise you get a black screen with nothing)

The Error Message is:

Software Failure
0000 0003 Task 00c03500

If you wait, machine resets itself and 30 sec. later, you see the same error. It is a loop.

Today, I tried another 3.1 ROM I had (I got it when I first got the machine), same error. So I am beginning to wonder if it is related to the board. I put the 1.3 ROM back and no errors, regular boot screen.
