024f9fccf8 "Fake" XDF disk support works now 
What this means is that XDF disk images formatted as 80-track 23-sector-per-track images will work with XDF code that honors that format; however, I've not yet been able to test with "real" XDF disk images (ie, disk images created with DiskDump using the experimental --xdf flag).  "Real" XDF disk images almost certainly need more work (eg, setting all the sector IDs properly), but the groundwork has been laid.

715e603ea2 Added --xdf option to DiskDump to enable (experimental) XDF support 
Without --xdf, DiskDump simply dumps an XDF disk image as a vanilla 80-track, 23-sectors-per-track disk image.
In addition, I regenerated all the PC-DOS 7.00 disk images without --xdf, to see if that works any better (it seems to work for VirtualBox)

997db9787b MODEL_5170_REV3 boots without errors now 
However, performance will suffer until I can implement RTC interrupts;
also, there may be a problem exposed by the BIOS memory test following a soft reset

0f06c3f039 The 5170 AT hard disk controller is limping along now, so I'm getting ready for a 1.15.4 release 
Some other interesting bugs were fixed along the way:
the Video component incorrectly assumed that masking a negative number with 0x80000000 would yield 0x80000000 (it actually yields -0x80000000, thank you JavaScript);
the ChipSet component provides a new addCMOSMemory() interface that RAM objects can use to bump the CMOS total to match the actual total;
the CPU properly implements INSW and OUTSW instructions now (kind of important for the AT hard disk controller)
