A4000D a3640 prob.... help is needed.

[Raist]

Hi y'all

This is my first time to write to this forum (hello to all:-) ), reason to write is that i can't seem to get my a4000 work with a3640 card. On the other hand the problem might not be the a3640 card, cause some progs works fine, but the computer is very unstable:(

Sometimes when i power up, powerled blinks, and "yellow error code" appear, that caused bad chip ram, right? so it might be memory error? On the other hand, sometimes it works fine, you can use WB like nothing is wrong, and then it might reboot suddenly.

And one mysterious thing, when i boot directly to the WB, it doesn't show the memory right (in the "upper corner" of the WB), just some silly bs or nothing). But when i boot without boot-up sequence, it shows memory (chip and fast) just right, what's the point?

The motherboard is rev C and a3640 is rev 3.0 (upgraded 3.1), is there any issues with these revs?

Sorry my bad english...

Did you have memory errors that i'm having, or just boot up problems? It might be the power supply also, i should try to change it if i can find one?

Battery has been moved away from the motherboard, and the motherboard is in good condition. So there isn't any leaking.

Oh, i mean the a3640 is ver 3.0 (there was some way to upgrade it to ver 3.0, am i wrong?)

Buster is version 11

I haven't got(yet:-)) any Zorro-cards, actually the daughterboard isn't connected, cause i had to change jumpers and so on, so the zorro-card isn't it's place.

I have tried many different 040 libs, some are working fine, some ain't. But it's look like a more hardware prob to me.

Ok, now i've done what you told and it works much better. It's been booting very nice, first time allways, without any power led blinks (for now).

How i can test that my daughterboard is working, without any zorro-cards? And another thing, WB is still showing the memory size wrong in normal (only characters and bizarre symbols or nothing). But if i boot without startup-sequence, and go to WB in that way, it shows the memory size correcly, why?
