| Temporary workaround for Grub2 Linux: BadRAM filtering |
|
For Unix-based distributions that use GRUB2 as a bootloader, BadRAM filtering can be used to exclude known defective memory addreses from being used by the operating system. This temporary workaround can be applied as follows:
GRUB_BADRAM="0x0000005729A5000,0xFFFFFFFFFFFFF000,0x000000211CC1000,0xFFFFFFFFFFFFF000"
sudo update-grub
|
| Temporary workaround for Windows: badmemorylist filtering in BCD store |
|
For Windows Vista and later, the Boot Configuration Data (BCD) store can be used to exclude physical page frames (PFN) from being used by the operating system. This temporary workaround can be applied as follows:
bcdedit /set {badmemory} badmemoryaccess no
bcdedit /set {badmemory} badmemorylist 0x5729A5 0x211CC1
