I'm trying to think of a way to make multi-CD installers work under Wine. Right now, the hardest part is that when the installers tell you to change discs, the Setup.exe file mappings are still open. I'm thinking of making Wine not map the file, but read it straight into RAM, if the executable to be mapped is on removable media.
But since to do this, MapViewOfFile needs to know the media type, and the file name is only known in CreateFile, I apparently need to store the media type in the wineserver object to accomplish this.
Would changing the wineserver protocol in this way be a good idea?
