process described above. HBIOS is installed in its operating bank
and control is passed to the Boot Loader.
## Boot Recovery
To assist users when driver faults or misconfiguration causes a boot
failure, RomWBW supports a limited recovery capability. This is
achieved by allowing the user to reboot their machine, loading
a minimal driver set. Implementation of this feature requires a
hardware input "BOOT RECOVERY" button to be available and
appropriate software configuration to be completed in the HBIOS.
When implemented, holding the "BOOT RECOVERY" button in after a
reset or power cycle will cause the normal driver load process to
be skipped in preference to a minimal set of drivers being loaded.
Typically this would be: Serial communication, RAM disk and parallel
port IDE interface drivers.
Platforms supporting this option currently are the MBC, Duodyne and
latter version of the SBC.
