Taito X2 CMOS battery replacement?

[jimmerd]

Hi,

Is there a known safe procedure for replacement of the battery on the Taito X2?

I understand that some Taito X2 motherboards keep security keys in the CMOS/BIOS.

I have a Darius Burst system and would like to keep it running the original drive/dongle if possible.

My fear is that the battery will run out of juice at some point as it's 10 years old.

I assume I can't just power up the system, unsolder the battery and add a new one and instead it may be more wise to to supply the correct voltages to the battery terminals
whilst the battery is swapped out.

Has anybody attempted this procedure?

Thanks!

The battery should be in a holder.

I'm pretty sure Dariusburst doesn't have any keys on the motherboard.

Anyway, I think motherboards usually have a cap in parallel with the battery, so if you have it running for a while before (to charge the cap), then shut it down and change the battery, you should be good.

Did you changed the battery by now? If so what was the result? Did you got some BIOS/CMOS messages during the first boot after replacing the battery?
