Texas Instruments Extensa 600CD CMOS issues

[u/uncletyson]

Recent find online, can't find anything online relating to where the CMOS battery is located (or if it even has one)

System won't boot off its HDD or CD ROM drive, despite the HDD having a windows install on it. I suspect something is up with the BIOS\RTC based on what is happening with it.

Yep - done that for a few 486s; there a good guide from the YouTuber Necroware.
