68a73dffe0 Give the Compaq Deskpro 386 its own set of CPUs 
Both BIOSes can now take a 16, 20 or 25 MHz 386DX,
with the 16 MHz one paired with a 287 FPU.

Also remove unused CPU packages from the enum

d7e125c16e Migrate configs for the Gigabyte Socket 4/5 machines (#4111) 
* Bring back machine migration

And add migration for the Gigabyte Socket 4 and 5 machines

* Fix the GA-586IS's internal name

* Remove legacy CPU tables for very old builds

Since backward compatibility with pre-build 2654 configs has been
removed, remove forward compatibility with these builds as well

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
