I'm wondering if anyone out there can help me... I'm looking for a code fragment that sets up timer interrupts approximately every 125 usec on a vanilla PC. From what I understand, this is possible by resetting the timer chip that causes INT 08, but unfortunately I don't know just how to do this. (I.e., is this register memory mapped or does it take some obscure I/O operation?) Thanks for any pointers, Steve Cole, scole@janus.berkeley.edu
