Yes, it has. The fix is built into the NitrOS-9 releases. You can read 
all about the technical side of the fix in the archive on RTSI

Hardly if you are using an emulator. Just mount a virtual hard drive and 
use that instead of an emulator. On a real Coco system, a ram disk can 
still be faster than anything else.

Yes, a ramdisk is contained in the NitrOS-9 release in the RBF 
directory. It is not included in the default OS9Boot file.

Vcc includes my modifications to RGBDOS which permits access to an 
emulated hard drive. All you need to do is turn it on.
The hard drive on that site already has (or did at one time) a version 
of NitrOS-9 installed. You just need to check the directories of 250-255 
one of which will be a boot disk that boot directly from the hard drive 
under RGBDOS.
