INT 0E C - IRQ6 - DISKETTE CONTROLLER Desc: this interrupt is generated by the floppy disk controller on completion of an operation Notes: default handler is at F000h:EF57h in IBM PC and 100%-compatible BIOSes may be masked by setting bit 6 on I/O port 21h DOS 3.3+ revectors IRQ6 to a stack-switching routine unless STACKS=0 has been set in CONFIG.SYS. MS/PC-DOS use the IBM Interrupt Sharing Protocol (see #02568) when hooking this IRQ SeeAlso: INT 0D"IRQ5",INT 56"DESQview",INT 5E"DoubleDOS",INT 7E"GO32"Top
INT 0E C - CPU-generated (80386+ native mode) - PAGE FAULT Desc: this interrupt is generated in protected and virtual-86 modes on attempting to access a 4K memory page whose page table entry has the "present" bit cleared Notes: used to implement virtual memory--when the page fault occurs, the operating system can load the appropriate page from disk a protected-mode program written in the Flat memory model will often generate this interrupt (typically reported as an Exception #14 or Exception 0E with a register dump) when dereferencing an uninitialized or corrupted pointer SeeAlso: INT 0B"CPU"Top
