! PMM services can be found by searching the BIOS rom area for the
! string $PMM, which is at the beginning of the PMM structure.
!
PMM_STARTSEG	equ	$E000		! start segment to look for PMM
PMM_SIGNATURE	equ	$4D4D5024	! PMM structure signature

PMM_SIGOFS	equ	$0000		! offset to signature in PMM struct
PMM_SREV	equ	$0004		! offset to PMM struct revision
PMM_SLEN	equ	$0005		! offset to PMM struct length
PMM_CHKSUM	equ	$0006		! offset to PMM struct checksum
PMM_ENTRY	equ	$0007		! offset to PMM entry point address

! Definitions for calling PMM functions. All memory blocks have to have
! a unique signature. We dont use a number as described in the PMM
! specification because that would mean to compute it at runtime, and
! that requires additional memory. Instead, we simply set it to a value
! which hopefully no one else uses.
!
PMM_RAMSIG	equ	$6E62676B	! signature of PMM memory block
PMM_FLAGS	equ	$02		! flags for memory allocation

PMM_ALLOCATE	equ	0		! function: allocate memory block
PMM_FIND	equ	1		! function: find memory block
PMM_DEALLOCATE	equ	2		! function: deallocate memory block
