Make an empty file on C: called Fragile
Put in Fragile allegiance CD and start dosbox.
mount c c:\fragile
mount d d:\ -t cdrom -usecd 0 -ioctl -label FA
d:
install
Install the largest option
Setup the sound while you are here. It should be able to auto detect the sound, make sure speakers are on when you test
Fragile allegiance is now installed.
You could play it right now, but it is unstable.
To make it stable, exit Dosbox.
Copy: _INTRO From the CD to c:\fragile
Copy: FRAGILE.ID From the CD to c:\fragile
Go to C:\fragile\intrplay\fragile <or where ever the game is installed> Edit CONFIG.INI file ensure it says SourcePath=D:
Start Dosbox.
Mount C c:\Fragile\
Mount D c:\Fragile\ -t cdrom
Enjoy the game with less problems.
<This may not work with the ripped version of the game.>
Iso version it might tho.
Next time you want to play
mount c c:\fragile
mount d c:\fragile\ -t cdrom
