Now it doesn't boot with any full 68030 (grey screen, tried two of them) but boots fine with EC030. Could it be something related to the MMU?
Not likely. I have the opposite issue anyways. The MMU CPUs work and the ones without them dont. I'll figure it out eventually. just strange.
The original pre_alpha firmware doesnt work?

It seems they all work fine with the EC ones only for the moment. The gold CPU works on and off randomly.
EDIT: The gold full cpu now booted with the firmware you just sent me but reports no fast ram. I put back the plastic EC one and it works fine, including ram. Very odd..

Ok. Experiment time.
Could everyone close the MMUDIS jumper and see if that makes a diff. Just want to eliminate the MMU from enquiries.

Sorry to be thick but where is that on the board

Not sure which right now

Also, Viktor and Mark, can you try a gold cpu and see if there is any difference for you?

Hi Alen
I have not got a Gold 50mhz cpu, but I have sent one of my TF330 builds to Steve so he can put one on it and compare results
**EDIT
I inputted " cpu fastrom" I jumpered both pins for the MMU and in sysinfo, open or jumpered it says" MMU in use"
am I doing something wrong lol

Its possible I screwed up the mmudis circuit. I’ll check later

Supaduper, that's a software issue. The CPU command cannot distinguish between EC030 and regular 030. So if you issue a CPU FASTROM on an EC030, the command will then report "68030 FASTROM" when queried, but you won't get the desired effect. For example, do a speed test on the IDE. Sysinfo will report about 2 mb/sec without fastrom and over 6.5 mb/sec with fastrom, and the entire system will be a lot more responsive if the fastrom actually works. There will be no change on an EC030.
I don't know how good Sysinfo is at distinguishing between the two CPUs, it could be the same as the CPU command.

Ok so I left the MMUDIS open(two pins furthest away from the TF330 connector) and did a` cpu fastrom` command and the did a `Drive speed` test in sysinfo on my DH0: part and the speed increase was there.
Then I did the same as above with the Jumper closed and the speed of the drive did not increase so the MMUDIS is working :)
