Does anyone have an exact list of register differences (and of c0urse missing or added registers on the EGA) between the EGA and VGA interfaces from a CPU perspective?
For some reason, UniPCemu's (S)VGA runs flawlessly, but the EGA (Basically modified status register inputs and disabled read operations for the Sequencer etc. register ports) doesn't want to POST properly?
I know that the horizontal total +3 vs +5, which is properly done on EGA, but why won't it properly POST?
