Alpha 2 3433 NVRAM driver mount failure

[LCards8086]

Hi all-

New to this, so please, be kind.

I picked up a Bally Alpha 2 that had been sitting around, unplugged for a long time.  I replaced all 3 batteries, thanks to other threads on this board.

Upon reboot, I'm getting the dreaded 3433 NVRAM driver mount failure fault.

I took it all apart, cleaned the contacts, and adjusted the contacts.  No luck with that resolving the error.

The machine came with no cards in the CF slots.

The machine did come with various .vhd files on an external hard drive.  I put what I believe to be an install .vhd (named 227207D 360 3 install.vhd) on a CF card and inserted that into the top CF slot in the machine.  I put what I believe to be the OS .vhd (OS 336E.vdh) on a second CF card and inserted that in the bottom CF slot.  Upon reboot, I'm still getting the NVRAM error.

I pulled the install card, replaced the install .vhd with what I believe to be a clean .vhd (RAM CLEAR Alpha 2.vhd) on that CF card, and reinserted that card into the top slot.  Upon reboot, still no luck, the NVRAM error comes up before anything else.

What can I try next?

TIA

After a battery change, you have to do a Ram clear then complete the machine settings and configure the game.

I thought I was doing that by putting the RAM CLEAR Alpha 2.vhd on the CF card and putting that card in the top slot.

Since that's not working, I can only assume that's not the correct way to do a Ram clear, but you know what they say about assumptions, so, what is the correct way to do a Ram clear?

Keep in mind I'm a beginner too.  Put the clear card in the top slot, then boot up. Wait for the clear screen to come up then make your selection NVRAM & EEPROM. Use the test button to toggle between options. Turn the attendant key to execute. It should indicate whether clear was successful. Power off, Remove the clear card, then boot up. This time it should boot up all the way then stop where you now have to configure the game.

Thank you, Dailey.

I'll give this a try.
