Guys, don't throw out the old Dallas chips! A good solution - eventually the only solution - will be to cut the traces to the internal cell and fit an external battery.

We've been here a few times before...


Be sure to adjust for the specifics of the device in question, but this should apply to most models with some slight (but important) variations.

Well funny you should mention that, I didn't see any guides that specifically addressed the DS1742. And the datasheet describes a 24 pin package with all pins in use, so clearly it isn't the same as reworking the older DS1287/1387 devices.

There's still room for you to blaze a trail, I think! :mrgreen:

on the subject of Dallas timekeepers, anyone ever seen a DS1187? From what little I've found about it online, it should be compatible with a DS1287 but with "different battery life". Longer or shorter?

WAIT. The Nekogods demand payment in the form of a hinv and photograph. Do it now before you risk our wrath. Especially smj, he's a right bastard when he doesn't get the hinv he deserves.

You mean I have to expose my fuel for all to ogle. Oh well. You shall have your pound of flesh. But a photograph, no way. It steals the soul and I cannot do that to the fuel.

I know this is a year old, but this is easier than pulling the snap hat.
I found that if you unplug the HDD then boot the system and press esc to get to the prom menu.
Press 5 and when the prom password comes up hit enter and go back to the menu.
Now hit 1 to start system and let it fail then hit enter at the boot error screen.
Once back to the menu hit 5 and it will go into the prom monitor.
Once there enter "resetpw" and the password is gone.

I have tried this on several machines and it works.
If the thing isn't on fire it's a software problem.

Ah yes, I remember this when I was over last. Worked perfectly.
