Ok try this badger...

https://github.com/terriblefire/terribl ... _alpha.zip

It works on the Rev 0 with a small speed hit. tell me how you get on with both Rev A and Rev 0.

NOTE: This alpha has the disable function removed.

Tested on TF330 rev3, with Akiko revA

All working here with just a small reduction in the Drive speed DH0: down to around 1,500.000, as you mentioned, Nemac IV chugging along nicely :)

This is clearly a rev2 board firmware - unfortunately it does not boot on my rev0, the console just gurus repeatedly (boots fine on the revA).

If flashed onto a rev3, the fast ram disappears, and then it boots on the rev0 akiko. So the clue here is in the fast ram...

I know what the issue is. But its booting fine for me on the rev2. i'll try the rev 3 victor sent me.

The issue isnt fast ram. its the clock switch. the REV0 akiko isnt tolerant of this for some reason. The reason fast ram is triggering it is because the CPU switches from 14Mhz to 50Mhz when accessing IDE or fast ram.

Ok, this seems to be true,
i recall the very first TF330 (rev.1) card was booting with no Fastram firmware,
wasn't able to let TF330 rev.2 to boot, hence was so frustrated
so this will be tricky..hope You will find a solution, Steve
