Falcon fitting a new battery

Postby Jammer » Sun Dec 23, 2007 10:06 pm

I've just given my Falcon its christmas present, a new nvram battery !
It was easier than I expected, I just cut the top off the chip with a craft knife, dug out the soft plastic exposing the old battery which I then removed and wired in a new one.
One small problem. The Atari boot logo was bigger than it used to be, so I changed the nvram setting to 2 colour and now it crashes on start up, I use a PC flat screen. Unless I can find a way to reset the nvram without opening the case again, remove battery etc. I'll have to dig out my Atari mono monitor and see if it will boot to that.
Happy Christmas everyone !

I can't help you with real data right now, but I'd tell you to don't worry: there is that NVRAM application that you can autoboot with from a floppy and fix all your problems.

Search the threads with the NVRAM replacement topic.

normly you could find it on DHS webpage but it seem to be offline at the moment

I attach it here

Code: Select all

F030Free NVRAM reset
A utility that resets your NVRAM in case you overclocked the CTCM too high or did some other bad NVRAM config. It must be installed to a floppydisk bootsector, so if your NVRAM is already messed up, you must find another atari to create the bootsector. The use of a bootsector program means that your Falcon doesn't have to boot up for the program to run.

You can reset the NV RAM settings by the following key combination:

Left Alt+Control+Right Shift+Undo

This combination resets the NVRAM settings to factory defaults, but still you need the german utility NVRAM.CPX (or similar) into your \CPX folder in order to customize the system settings according to your needs.

Hope I helped,

Fixed thanks.
I tried key combinations and found control, alt, right shift, undo booted to a low res screen where I could get at the floppy and run bootconf.
Still can't get the Atari logo exactly as it was, but at least its all working again, correct time and date after being turned off all night.
Yippee ....

you must load nvram.cpx in control panel and put vga/rgb, 80 columns, 16colors and/or overscan for bootup.

this puts hires during boot.
