I want to run freedos bare metal and have it work but also start working on a new OS that will work on UEFI bios.

Can anyone confirm which platform is best for this?

Im considering the
ASUS Z170-WS Motherboard ATX Intel Z170 LGA1151
and
Intel Core i7-6700K 4.00 GHz LGA 1151

From what Chatgpt has told me and what ive been able to find, this should fit the bill?

I also plan on using a StarTech.com PCI Express to PCI Adapter Card and using a Trio 64 gpu or voodoo 3.
