Hello. How does one locate the information about the CPU state before an interrupt call while within the handler? More specifically, I want the origional state of the registers (all of them) at the time the interrupt was called, or at least to know how DJGPP stores them. It seems that DJGPP gives each interrupt handler a new stack, and I don't WANT it to do this, but I don't know how to avoid it, so I just want to be able to access the stack of the location where the interrupt occured. Thanks.
