[GUIDE] DSDT override to fix error 12
no more 4GB+ system RAM issues: use a DSDT override to extend the root bridge into 36-bit space (Windows 7/8/10 only - MacOS/Linux are unaffected)

Win8/10: Perform a DSDT substitution within Setup 1.30 to overcome TOLUD issues
Win8 enumerates the DSDT table from the in-memory copy on every boot as it's default behaviour. The only way to get it to allow a Win7 style DSDT override is to enable test signing for the Windows bootloader (bcdedit) as described here.
An alternative method was also discovered to overcome this Win8 limitation without resorting to a DSDT override. The way it works is by substituting the in-memo
