OsxAptioFixDrv and OsxAptioFix2Drv reverted to rev before 4368 so without NVRAM support. Let them stay here for history. And sometimes OsxAptioFixDrv is only working version for high warped memory map.
OsxAptioFix2Drv is a reduced version without relocation blocks and may not works on some hardware or with older OS version. But this version supported Hibernation while first one no.
OsxAptioFix3Drv is a OsxAptioFix2Drv rev 4369 renamed to be different. This version supported NVRAM. More runtime fixes in 4379. This version can be improved by clover crew in future.
AptioMemoryFix included in the package is third-party memory fix driver used as is. It is probably better then OsxAptioFix*. Choose it for a first attempt.
OsxLowMemFixDrv is also memory fix driver, not improved since rev608.
SIC! These 5 drivers should not be used simultaneously! Choose one of them!
Clover will be updated for mutually exclusion.
AptioInputFix is included in the package now. It is keyboard driver to support FileVault2 for those who have AMI UEFI BIOS.
