This setting controls whether fixed disk access is performed through Windows protected mode drivers or through real mode drivers and BIOS routines. If you are experiencing drive IO errors enabling this setting may be a possible solution.

Open your registry and find the key below.

Create a new Binary value, or modify the existing value called 'ForceRMIO' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.


(Default)	REG_SZ	(value not set)

System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem]
Name: ForceRMIO
Type: REG_BINARY (Binary Value)
Value: (00 00 00 00 = protected mode, 01 00 00 00 = real mode)
