i am developing a simple os for prototyping purposes. i have until now enabled paging and written the enabled the PIC controller.the IDT entries have also been made. i have also enabled the interrupts. now if i give a jmp $ statement a general protection interrupt is generated. could anyone plz tell me the reason?

there must be an other reason for the GPF sincd the jmp $ does nothing (really nothing), but hang.
try:
cli
jmp $
maybe an hardware is generated, the idt somehow wrong and we got the #GPF. i'm entirely sure that the jmp $ is not the reason - you may post code.

Try duping letters to screen, to see how far your os gets.
