In order to get an accurate and stable clock to play OPL2 BGM, I need to reprogram the 8254 to obtain a higher frequency int 8h.
However, after consulting a lot of information, it seems that this is quite cumbersome for DJGPP.
PCTIMER (https://technology.chtsai.org/pctimer/) seems to fully meet my requirements. After dealing with some minor issues, it compiled successfully.
However, I found that although the program seemed to be running, the real-mode handler named rm_new8h was not called at all, and the original BIOS handler was still called 1:1.
What is the problem? Thank you so much!
