Yesterday, I experienced the following problem:
I have an interrupt (print screen key) routine conntected to int 5.
After booting, the interupt address is: FF000:FF54 which is owned by
BIOS, next using Norton SI to set screen mode to 80x50 lines, results
in a vector to 02D5:37E3 which is Dos system area, and my interrupt
routine which was installed before DOS takes over, no longer get 
called at the press of the print screen key.

Anyone who has any idea of how to solve this problem? 
(I prefer not to take control over int 09)
