Processor Configuration Registers  
2.5.33  
BDSM—Base Data of Stolen Memory Register  
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).

BGSM—Base of GTT Stolen Memory Register  
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
