The Adlib chip sits at I/O 388/389. The Gravis Ultrasound cards also use those I/O addresses to emulate the Adlib in S-BOS. As I understand it, normally the Adlib emulation is totally disabled unless S-BOS is installed. Mega-Em emulates Roland and the digital functions of a Sound Blaster, but not FM Synthesis. S-BOS emulates a full Sound Blaster.
Suppose you had an Adlib or Sound Blaster in a system and a GUS. Naturally you would wish to use the Adlib/Sound Blaster for all FM music. Most games detect the Adlib chip and complain if they cannot find one. I assume the Ultrasound ACE had an FM/Adlib disable jumper to avert any potential conflicts with an Adlib or Sound Blaster, as the card was designed to work alongside one of these cards. But the other GUS cards do not.
Has anyone ever had a problem like failing to locate the FM chip which was solved by removing the non-ACE GUS from their system?
