TIL about BDSM

A BDSM register

#Embedded #Intel #Hardware #Processor #CPU #Tech #Technology

Base Data of Stolen Memory (BDSM_0_0_0_PCI) – Offset B0

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 BC bits 31:20).

Bit Range: 31:20
Default: 0x0
Access: RW/L
Field Name and Description: (BDSM) 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 50 bits 15:8) from TOLUD (PCI Device 0 offset BC bits 31:20).

Bit Range: 19:1
Default: 0h
Access: RO
Field Name and Description: Reserved

Bit Range: 0
Default: 0x0
Access: RW/L
Field Name and Description:
(LOCK)
This bit will lock all writable settings in this register, including itself.

My latest blog post: VanSpoof - Prototype 2 - Echo Firmware

https://mikecoats.com/van-spoof-prototype-2-firmware-1/

In part 1 and part 2 of building my first VanSpoof prototype, I managed to flash the microcontroller on the PCB with a blinky demo. This time round, let's see about sending and receiving some serial data.
