INT 00 C - CPU-generated - DIVIDE ERROR Desc: generated if the divisor of a DIV or IDIV instruction is zero or the quotient overflows the result register; DX and AX will be unchanged. Notes: on an 8086/8088, the return address points to the following instruction on an 80286+, the return address points to the divide instruction an 8086/8088 will generate this interrupt if the result of a division is 80h (byte) or 8000h (word) SeeAlso: INT 04,OPCODE "AAD"Top
INT 00 - Zenith - ROM DEBUGGER Desc: invokes the ROM Debugger when at the BIOS level; equivalent to pressing Ctrl-Alt-Ins on booting. Note: since DOS revectors INT 00, it is necessary to restore this vector to its original ROM BIOS value in order to invoke the debugger once DOS loads SeeAlso: INT 03"Columbia"Top
