1242 memory_corruption_check=0/1 [X86]
1243 Some BIOSes seem to corrupt the first 64k of
1244 memory when doing things like suspend/resume.
1245 Setting this option will scan the memory
1246 looking for corruption. Enabling this will
1247 both detect corruption and prevent the kernel
1248 from using the memory being corrupted.
1249 However, its intended as a diagnostic tool; if
1250 repeatable BIOS-originated corruption always
1251 affects the same memory, you can use memmap=
1252 to prevent the kernel from using that memory.
1253
1254 memory_corruption_check_size=size [X86]
1255 By default it checks for corruption in the low
1256 64k, making this memory unavailable for normal
