It's ARM based for which Wiki says:

"Non-x86 PC/104 CPU boards based on ARM or PowerPC are also
commercially available. However, such boards are not capable of
running off-the-shelf PC software. In these cases, a Board Support
Package is usually provided by the manufacturer for the supported
operating system(s)."

WRT x86 I run the search
https://pc104.org/product-search-results/?kw=x86&post_tag=&product_type=&specifications=&pc-bus-technology=&user=Filter+by+Member+Company
seems like all of them are based on Vortex86DX.
