FILO never invokes GRUB. FILO has it's own code that implements
GRUB-like functionality.

Yes, _the specified drive_ has to start before FILO can read from it.

But not _every drive_ needs to be checked, because the correct device
has to be specified beforehand.

The issue is not with filesystem structure. The issue is with drives.
Scanning drives takes some time, at least a few seconds per drive or
so.

Once the correct drive has been found, finding the boot files is
usually quick because only few sectors needs to be read.
