Since the EFI is ok using the old EFI Restoration did not work.

Does anybody know how to force EFI flash with the current version, when you are at the current version. The changed behavior indicates corruption.

PCie eSATA disks are not reliably enumerating even with new cards and disks. The controllers always show the controllers properly.

Controllers and disks have been stable for several years before this started.

EFI Restoration CD, when it works, don't work to downgrade firmware. Before 138.0.0.0.0 you could rename the previous version to a new one to fool efiflasher, this don't work anymore.

The only way to downgrade nowadays is reconstructing the BootROM and flashing the reconstructed one with ROMTool.
