I know it's a picky SOB but jeebuz...
I was playing a game via CF and shut it down to swap out CF cards not touching the DIMM and I can't get it boot past the splash screen with the "Error 01" code. It's worked fine for years. Voltages are on point, 3.3 & 5. I've cleaned contacts on the mobo, DIMM & GD drive cable. Removed the DIMM and reseated it numerous times. I've pushed in the BIOS and Zero chip and that damn Error 01 message keeps taunting me... Is this a bad mobo or DIMM?
 
Do you still have a battery in your dimm? I thought my voltages were fine but it was actually dipping just enough during boot to give errors and only sometimes.
 
Sounds like that "Bad Load" issue with CF cards sometimes. When you see the boot taking a bit longer to load while in the Naomi's white boot-up screen, pull the power cable on the CF reader then reinserting it, essentially just rebooting the reader to try to load it again.

Now-a-days I have the CF reader from @Tailsnic Retroworks that has a relay switch and a small Arduino that resets the CF Reader automatically when a bad load occurs. Sometimes it'll reset a couple times before a good load happens.

there is a battery and it doesn’t seem to have any juice.

I tried the power trick and didn’t change anything.

I’m leaning towards the DIMM croaked? I moved the jumpers around to try and NetBoot but I still get the message and when I go into the test menu I don’t see network settings option.

I used to NetBoot then I got a CF set up and now seems like neither are working…
 
Does having a battery matter at all for CF? It certainly doesn't seem to matter when loading from GD.
Having the battery hooked up causes the charging circuit to have a load and can cause a voltage drop during boot.
