[Coco] HDBDOS (IDE) & MESS (Coco2)

[Bill Pierce]

Juan, I didn't realize you could do it that way, where are the parameters to set up the CF image in DW and how do I set it?

I use XRoar and the "Becker port" version of HDB-DOS. Then you serve the
image through the DriveWire server, which can be configured for that. Works
beautifully.

If I'm not mistaken, that can be described as paravirtualization. Am I
making sense?
