6F corresponds to IRQ23 on the original HP Vectra AT, which is unavailable because of its use as a BIOS extension software interrupt the INT 6F handler consists of an instruction to load DS with the driver's data segment followed by an indexed far jump using BP to select the destination vector; since the interrupt handler is located immediately following the dispatch table, the HP_VECTOR_TABLE may be found by looking at offset 0000h in the INT 6F segment, and its size is equal to the offset of the interrupt handler each entry in the HP_VECTOR table consists of a DWORD for the driver's entry point address and a WORD for the driver's data segment this function is not user-callable, as it is a response to a physical event, and assumes that the caller has already handled the physical

It utilizes some undocumented 386+ features to enable 4G code and data segments (flat memory model) in the CPUs real-mode. It is not compatible with V86-mode (as with most EMM386).

Routines in extended memory may only be called with interrupts disabled (only usable for very short routines). If the two stage interupt model is enabled, these conventions are not required. The outer (transparent) ISRs save the higher word of EIP in the high word of CR3 (possible modification: in memory, if this is not safe) and then invoke the standard ISRs. Because of this handling, one should use pseudo segmented code even in extended memory (64K blocks located on 64K boundaries) to avoid the misalignment of the saved EIP (in CR3).
