Base of Stolen Memory (BSM):
This register contains bits 31 to 20 of the base address of stolen
DRAM memory. The host interface determines the base of
graphics stolen memory by subtracting the graphics stolen
memory size from TOLUD. See Device 0 TOLUD for more
explanations.
Reserved
NEXT_PTR:
This contains a pointer to next item in capabilities list. This is the
final capability in the list and must be set to 00h.
CAP_ID:
SIG defines this ID is 01h for power management.
