I guess, it is somehow related with BIOS (BIOS should be CGA-compatible, like AMIBIOS dated 1988-1994 years). These AMIBIOSes were having special settings for CGA adapters... Besides, I found also it was somehow related with CGA VideoMemory access time... video cards with slower memory chips couldn't work even with 486SX motherboards... I had to replace those chips with faster ones to make them working stable...
What's about the software? As I can guess, it is DOS-based software... Because the last Windows OS supporting CGA adapters was Win3.1...
Even Win3.11 already did not support them anymore...
If so, why you needed faster motherboard? As it was already suggested, you can find an old 486 motherboard or complete system for free (or almost for free)...
