When i connect a ZIP and/or DVD drive to my A4000, using a A3640 card, the system doesn't boot. While disconnecting the ZIP/DVD drives my A4000 boots again.
Interestingly enough the ZIP and DVD drive are working in the same A4000 when i exchange the A3640 for the 030/25MHz card.
I have made a detailed overview on my blog.
Can someone help me on this brain cracker?
Ok, if i am reading your blog correctly, then you have hacked the 4000 ide gal for faster speed and you are using the 4 way adapter.
Looking at the picture of your A3640 ,it is actually a rev 3.2 (notice the -03 on U209 gal) which is a good thing.
From what you say it seems its either a 4 way adapter problem,or the 4000 ide Gal hack is causing this incompatibility. Is it socketed? can you go back to the pio0 gal for a test? since removing the drive cables makes the machine boot i would think it might eliminate the 4 way adapter and blame the ide Gal chip on the motherboard but this may not be the case.
This is just a shot in the dark,but you might try cutting the pin 1 wire on the 40 pin ide cables(this is the red stripe) if you have some spare cables-I recall a 4000 with a problem living with 2 drives and cutting this wire sol ved the trouble,but my memory is not that good.
does this use idefix for the other channels?
