I assume the EPIA-V board is the oldest version ? VIA on their website only mention
EPIA EK , CN, EN, SP, ML, MII, M, but no V
Anyway I have tried to get linuxbios to boot on my EPIA 5000 (vt8601 northbridge) I do not even get any comms from the serial port. Have checked the cable is ok, by booting normally.
I only have 100Mhz memory installed, as it was going spare. Could this be a reason why it does not work ? Anyway have just downloaded the vt8601 datasheet so will have a read through it and the code when I get some time and go through the code. Perhaps I will try and get some 133Mhz ram and try with that also.

It was indeed set to 115200 N81, but I just experimented a bit and found that it worked on 19200 baud (with some garbage at the top, though). :)
Oh thats right.. There is some freaky divider issue with the EPIA... Need to document that somewhere.

I guess that's a pretty good indication that RAM isn't working, right?
Yeah. Look in the code and you will find a simple RAM test. It will show lots of bit errors and then total failure.
So to get back to debugging this, do you have any idea of a time when the 8601 code was working?
Sorry no.. You will just have to go through the entire log and pull revs all revs that deal with the 8601. Sorry I don't have any more info. Most of the people who worked on that don't seem to be on the list anymore.
Was it while LinuxBIOS existed in Subversion
(there was a CVS repo some years ago, wasn't there)?
Right but Stefan back ported all the stuff to svn.
