Several FDC improvements and the behavior is now a bit closer to real hardware (based on actual tests);
Added MR Intel Advanced/ATX with Microid Research BIOS with support for 4 floppy drives and up to 4 IDE controllers;
Added floppy drives 3 and 4, bringing the maximum to 4;
You can now connect hard disks to the tertiary IDE controller;

Overhauled DMA channel read and write routines and fixed cascading;
Improved IMG detection of a bad BPB (or complete lack of a BPB);
Added preliminary emulation of PS/2 1.44 MB and PC-98 1.25 MB 3-mode drives (both have an inverted DENSEL pin);
