GBSM - Graphics Base of Stolen Memory
B/D/F/Type:
Address Offset:
Default Value:
Access:
Size:
This register contains the base address of graphics data stolen DRAM memory. BIOS
determines the base of graphics data stolen memory by subtracting the graphics data
stolen memory size (PCI Device 0 offset 52 bits 7:4) from TOLUD (PCI Device 0 offset
B0 bits 15:04).
This register is locked and becomes Read Only when the D_LCK bit in the SMRAM
register is set.
BGSM - Base of GTT Stolen Memory
B/D/F/Type:
Address Offset:
Default Value:
Access:
Size:
This register contains the base address of stolen DRAM memory for the GTT. BIOS
determines the base of GTT stolen memory by subtracting the GTT graphics stolen
memory size (PCI Device 0 offset 52 bits 9:8) from the graphics stolen memory base
(PCI Device 0 offset A4 bits 31:20).

Graphics Base of Stolen Memory
(GBSM):
This register contains bits 31 to 20 of the
base address of stolen DRAM memory.
BIOS determines the base of graphics
stolen memory by subtracting the
graphics stolen memory size (PCI Device
0 offset 52 bits 6:4) from TOLUD (PCI
Device 0 offset B0 bits 15:04).
Note: This register is locked and becomes
Read Only when the D_LCK bit or
MSLOCK in the SMRAM register is set.
