So I bought a hydro thunder board + the diego with the wiring to fiddle around with, however when checking to see what error pops up with another video card, I see it's the keyboard initialization one. The diego is connected to the main board's power + serial. However my question is does the diego need to be connected to the driver board to boot past this error?
 
Nope it does not. Be sure that you have the I/O board connected to COM 1 and that it is set correctly in the bios. You will know when it is working right the LED's on the Diego board will flash differently. They "pulse" when not initialized and kind of sequence when it is sending and receiving data.
Also Be sure to have the Hydro Video card in PCI slot 1. Second big issue is that some "extra" normal video cards will piss off the OS and it will pop out errors. You need a AGP VGA card to see post the one I had luck with was a voodoo3 AGP 16 meg. None of the Nvidea cards I tried played nice with the PharLap OS
 
Cool, appreciate the answer. Are the COMs just "Auto" in the bios? Though, it might help if someone created a thread that had all of the settings after a dead battery change heh

Oh I should note that this happens either on the security less chd with a gauntlet legends voodoo 2 or a regular one with the hydro thunder card, so i don't think it's the card itself.
 
I replied in PM but I wanted to also post here... Do you have the "original" Serial cable? IIRC these used a NUL modem cable not straight through. But as stated in the PM It has been a while sense I looked at that so I could be wrong.

Yeah that sounds like it could be it. I'll get one tomorrow and report back, thanks!
