This is a hardware emulation of the MPU401 - requires an OS be downloaded onto the card at bootup. >Description: Basically, using the Tropez in MPU401 mode pagefaults the kernel. One tries to play a midi note, and *boom*, down goes the system. >How-To-Repeat: Boot DOS. Run setupsnd.exe and load oswf.mot into the soundcard. Either c-a-del or run fbsdboot.exe. playmidi -e *bang* there it goes. This method (boot dos, configure the card, then boot to OS of choice) has worked with OS/2 and Linux in the past. >Fix: Workaround: use the really crappy OPL3 on the card.
