I'm usually hack the Dallas RTC to use a CR2032 coin battery or if it has award bios in eprom chip, I modbin it to change the 1.2MB floppy drive to 1.44MB drive.

I was thinking of performing this hack, but im still looking for a good resource describing the process. Know any?
Here is the pinout:

Here is a really good and handful draw and modified RTC chip:

I learned from this video: https://www.youtube.com/watch?v=NdlSfqto_0o
Note that you have to watch the process carefully.
The internal pins of the coin battery do not connect to the external pins that are next to it.
That's at least what I found out about my Dallas chip(s), which I opened with a file.

I've bought 3 new Dallas batteries on ebay from China, free shipping and I've paid only 4 $. I think it will be ok for me for next few years.
But I've noticed an issue that if I set the date like 2018 in bios after reset, the date goes crazy and its 2098. Time, day and month is ok.

Sounds cool, but keep in mind that some of these could be NOS parts. Better check the production date, too. 😉

When does it happen ? in CMOS Setup or in DOS, Windows 3.x, Windows 98 ?
The most relevant reference on the web was this:
Fixed the problem of date wherein sometimes the year will change from 1998 to 2098.

If its an issue of the BIOS or RTC, you can run some Y2K test programs.
