More specifically the culprit ist that the BIOS update is too large for
the ISO9660 bootarea which emulates a floppy disk, i.e. at max. 2.8 MB.
The BIOS image + DOS + utility does not fit. So you need access to the
full CDROM with ISO filesystem and USB CDROM driver. This is pitifully
not part of the disk image that Lenovo provides.
But it works for e.g. an embedded controller update where the image is
way smaller.
