795a6017d2 PIC rewrite, proper SMRAM API, complete SiS 471 rewrite and addition of 40x, 460, and 461, changes to mem.c/h, disabled Voodoo memory dumping on exit, bumped SDL Hardware scale quality to 2, bumped IDE/ATAPI drives to ATA-6, finally bumped emulator version to 3.0, redid the bus type ID's to allow for planned ATAPI hard disks, made SST flash set its high mappings to the correct address if the CPU is 16-bit, and added the SiS 401 AMI 486 Clone, AOpen Vi15G, and the Soyo 4SA2 (486 with SiS 496/497 that can boot from CD-ROM), assorted 286+ protected mode fixes (for slightly more accuracy), and fixes to 808x emulation (MS Word 1.0 and 1.10 for DOS now work correctly from floppy). 2020-10-14 23:15:01 +02:00

e7b8bda771 Implement clock-dividing for FPUs on clock-multiplied 386s 
This is done by making it so that if the FPU is not at least a 487SX, the clock cycles are multiplied by the CPU multiplier.

a862bda04c Rewrote the recompiler interrupt checking in assembly (and removed it for the new dynamic compiler because the requires uops are not present), brings performance back up, and also did a number of CPU-related clean-ups (mostly removal of dead variables and associated code). 2020-07-13 19:46:19 +02:00

96228bc41d Overhauled the SiS 496/497 chipset emulation (and added the DRB locking to it) (later Zida Tomato 4DPS BIOS'es now work, and we now use the actual 1.72), fixed the W83787F and FDC37C932FR Super I/O chips, removed the no longer needed Acer M3A registers (that's now correctly handled as FDC37C932FR GPIO), and a number of bugfixes here and there. 2020-06-29 01:10:20 +02:00

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.
