Hello All,

Does anyone have any experience hooking the real time clock interrupt 0x70.

This apparently ticks 1024 times a second, without reprogramming the PIT.

I have followed examples in the PC timing FAQ and information from 
Mark Feldman (of PCGPE) fame but to no avail.

If anybody has any experience of getting this to work and could offer
me some advice then I would be extremely grateful.

Cheers

John
