You just a programable timer..... no problem.  I just happen to have the
right book for you here then. Pc Programmer's Guide to Low-Level
Functions and Interrupts, by Marus Johnson...
anyways..  int 08H is called 18.2 times a second... that might help, by
if you intercept this vector you MUST call the original procedure 18.2
times a second.. It takes  care of a few things for you.
There is a PIC (programmable Interval Timer) on the PC here's how to
program for it.
Port
40H     Counter 1
41H     counter 2
42H     counter 3
43H     CONTROL WORD
PIT CONTROL WORD FIELDS
BITS
7-6         00 Select counter 0
            01    "     "     1
            10    "     "     2
            11 ILLEGAL
5-4         00 Counter latch command
            01 Read/write LSB only
            10 Read/Write MSB only
            11 Read/Write LSB THEN MSB
3-1         Mode 0 to 5
            110  Mode 2 but not recommended
            111  Mode 3 but not recommended
0           0 Binary count
            1 BCD count
Modes   0  interrupt on terminal count
        1  hardware triggerable one-shot
        2  rate generator
        3  square wave mode
        4  Software triggered strobe
        5  Hardware triggered strobe
