INT 6F - HP Vectra EX-BIOS - "F_ISR" (internal) - RESPOND TO LOGICAL ISR
AH = 00h
BP = ID for driver (see #03741)
DH = data type (see #03742)
DL = physical device driver's index (driver ID / 6)
BX,CX = data
ES:0000h -> physical device's Describe Record (see #03749)
---keypress event data---
BH = keyboard state (only if bit 5 of DH set) (see #03743)
BL = scancode (if bit 4 of DH clear)
CX = number of scancodes in list (if bit 4 of DH set)
ES:SI -> scancode list (if bit 4 of DH set)
---motion event data---
BX = new X position (abs device) or X increment (relative device)
CX = new Y position (abs device) or Y increment (relative device)
---button event data
BL = button information
bits 15-8 reserved
bit 7: button state (0 = down, 1 = up)
bits 6-0: button number (0-7)
BH = reserved
Return: AH = status (see #03744)
BP,DS destroyed
---if device is keyboard translator---
BL = translated scancode
BH = new keyboard state (if DH bit 5 set) (see #03743)
DH = new scancode type (see #03742)
Notes: INT 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
interrupt and updated the Describe Record (see #03749) to reflect
the event
