Can anyone out there in netland help me?
I am using a 12Mhz IBM AT clone.
Here is my obstacle:
    I wish to program an interrupt associated with a timer that calls the
    interrupt 8000 times per second.
Here is what I have done already:
    I have used interrupt 1CH and changed the 8253 timer from the standard
    18.2 hz to 8Khz but this has an adverse side affect, it calls interrupt
    08H 8000 times per second which make my system crawl.  I dont know what
    interrupt 08H does, but if you disable it, the system locks.  Also, if
    I hook 08H instead of 1CH, I could theoretically call the original 08H
    at 18.2 hz, but the system locks all the same.  So it appears that 08H
    MUST be called every timer pulse.  
Here are my questions:
    why must 08H be called every timer pulse?  what does 08H do that takes
    so long.  Can I use another timer?  
Thank you.
Please respond to trux@atop.cs.caltech.edu because I dont read this newsgroup
very much.
