Processor Configuration Registers 

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 
BCh bits 31:20).

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 52h bits 9:8) from the Graphics Base of Data Stolen 
Memory (PCI Device 0 offset B0h bits 31:20).

Graphics Base of Stolen Memory (BDSM): 
This register contains bits 31:20 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 BCh 

bits 31:20).

Graphics Base of GTT Stolen Memory (BGSM) 
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 52h bits 11:8) from the Graphics Base of Data Stolen 

Memory (PCI Device 0 offset B0h bits 31:20).
