On what machine with what OS, hardware & drivers? A LOT of BIOS extensions,
device drivers, and OE's (DESQview and Windows) intercept and functionally 
remove this service. INT 19H should really not be used, as it doesn't do
a lot of house-cleaning that a re-boot does. (Remember, int 19 just performs
a boot-strap load). This is already in the FAQ list (come on people, read the
FAQ first!) To do a cold boot, make a jump to FFFF:0, to do a warm boot
write a 1234H into address 0:472H then make a jump to FFFF:0, this will boot
the machine without running the POST. This is a much more bulletproof meathod.

Hope this helps ....
Steve
