b6581dab8b 386: Re-add the INVD and WBINVD instruction - the DataExpert Phoenix 4.03 BIOS uses the latter even when specifically detecting a 386, who knows what it did on an actual 386. 2024-10-19 22:38:05 +02:00

b1c5cbaf47 Split the 286/386 interpreter away from the 486+ one (the 286/386 interpreter does not use the pccache's, readlookup's, and writelookup's as the emulated CPU's are too slow for them to be required, and also has more accurate FPU timings), also added a LPT status read function for future-proofing. 2023-08-08 19:39:52 +02:00
