consult with UPD720201K8-711-BAC-A

Dears

 

We use UPD720201K8-711-BAC-A, and I would like to consult with a question. Our host computer is an Intel CPU. According to the current debugging results, it is no problem to use it after starting windows normally, but we need to enter DOS or BIOS and hope it can be used during the boot process. In this case, we cannot use UPD720201K8-711- BAC-A, is this support? What should I do if I support it?

 

Thanks
