Today, I encountered my second 430nx based board, and it had the exact same issue as the 1st board I had tried to get going about two years ago.
Basically, it seems when the Dallas RTC's die on these boards, replacement does not work.
The first board was a Packard Bell LPX board, after replacing the dead Dallas chip with a Glitch 12887, It would refuse to actually save bios information, and on each reboot, the data on the chip would become corrupted (odd dates and times showing in BIOS, settings changing automatically, etc). Trying a brand new NOS 12887 had the same issue. Replacing the original dead chip would stop these errors from occurring, but obviously no data was saved. I attempted to battery mod that chip but had a slip of the hand with my dremel, broke it beyond repair, and that board became a paperweight.
Yesterday, I finally got a CPU that would work in my NOS Micronics M51PI mainboard, also using the 430NX. Upon first powerup, it complained of a dead battery. It's socketed, so I threw a Glitch 12887 in there, and it exhibited the exact same symptoms as the 1st board. Identical failure. Replacing its original dallas, gives the same "fix" to the data, but no ability to save through power cycle. I am planning on trying to battery mod the original Dallas, and be a bit more careful on this go around.
Doing some reading, I found several threads of people with 430nx boards having the same problem after their Dallas dies. I found a few references to certain boards requiring the Dallas to be pre-formatted in some way, but no details in what that entails, or how to perform this procedure (if it's even possible for a home user)
So, I'm wondering if anyone else has had this issue with the 430nx boards, and does anyone have any details on how to preformat these new RTCs to make them play nice with this chipset. Is there a reader I can plug the Dallas into to dump the data in the flash, and then upload that to the Glitch?
Thanks in advance!
