Hi. I have a broken 1.1 console. It had TSOP Flash and Dual BIOS. But I break away a cable to point A19 with its track...

I mount an Aladdin chip, run console, and tried to flash with 1MB BIOS, but I get message "unwritable/flashable". The switches are good.

Is there any posibility to repair it? I don't want using an Aladdin chip all the time...

You can't flash the TSOP after booting up the console with an LPC modchip. There might be an alternate point for A19 somewhere but I'm not sure. You might also be able to expose the copper trace that leads to A19 and solder to that instead, but if you're not confident in being able to do that, then i wouldn't risk it.

I unplugged a modchip after console start and then tried to flash TSOP.


I borrow another 1.1 motherboard. But I can't find point where the ends of broken track are connected.

The track is completely broken, I can't fix it.

I need info where are another points for these 2 points:

You cannot do this. It will not work.
If you want to flash TSOP, you must boot from TSOP.

So I have a bigger problem than I thought. So I must to reactivate dual-bios... I need to connect these 2 points, can You help me?

The track will end up at the TSOP. Search for a spec sheet. You could try to reconnect it from there to a valid trace. Or just ground it and you will only have a two 256k banks, or one 512k. Assuming it is already flashed it should work. I don't think you will be able to flash it again.

I found that A19 is connected to first pin of TSOP. I connect it, but no effects. Eventually I decided to mount Aladdin :] Thank you...
