f62fc73862 (Re-)added the Deskpro 386, but only in the development/incomplete section of the code definitions. 
Selected XT and AT clones can use either their built-in FDC controller or an external one (the IBM AT and Compaq AT machines don't support booting from a 1.44M floppy so this makes the external floppy useful).
Added the FDC to the Adaptec AHA-154xCF ("2" variant) and defaulted to None to keep compatibility with existing FDC's.

3e8d27d015 Fixed FPU on RapidCard onwards (fixes OS/2 on RapidCard onwards to no longer think it's a 287) and renamed the Built-in FPU to Internal to be consistent with the rest of the emulator. 2020-06-15 22:49:30 +02:00

3dd3396a2c Backported the codegen_accumulate functionality to the old recompiler, so Windows 98 first edition on i686 CPU's can stay fixed without i686 timings getting messed up. 2020-05-06 03:41:46 +02:00

f29f6de245 Redid the x87 merger, now the x87 interpreter is basically the same across both recompilers, and there's several newly introduced bugs less. 2020-04-10 14:07:25 +02:00

2a0b3eb9c5 Added PAE, ported K6, P6, and WinChip 2 timings to the old recompiler, added a bunch of CPU's to the old recompiler, done some x87 fixes for both recompilers, added PAE, and fixed root directory entries for single-sided 5.25" DD floppies in the New Floppy Image dialog. 2020-04-10 01:08:52 +02:00

a505894a10 Move all include files to src/include 
- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root

8e1c0f5337 CPU table revamp 
- Added IBM 486SLC2/40 because somehow I didn't know it existed
- Revoked Dynarec support on the IBM 486 CPUs after several PS/2 machines were buggy with it
- Disallowed Pentium OverDrive and 3.3V 486 CPUs on the AMI 486 clone, Award 486 clone, IBM PS/1 2133, and IBM PS/2 model 70 Type 4 due to discovery that they used either Socket 1 or the original 486 socket
- Disallowed split-rail voltage CPUs (P55C, 6x86L/6x86MX, K6) on all Socket 7 FX and some HX motherboards that don't support it
- Fixed a lot of wrong multipliers on 5th-generation CPUs
- Added mem and cache cycles for the faster K6-2s/K6-3s above 300 MHz

c6ee6f48de Removed an unused table from the XT MFM controller code; 
808x prefetch queue is now always cleared on soft reset (as it should be due the changing CS:IP).
