Description
This function is called when booting from an unconventional device such as a PARTIES
partition and/or executing hard disk diagnostics. All other BbsTable entries are set to
ignore and, depending upon
Attributes, one or two entries are created. If executing
hard disk diagnostics, a
BbsEntry is created and given the highest priority. If booting
from an unconventional device, a BbsEntry is created and given the highest priority
after the diagnostic entry. It is the caller’s responsibility to lock all other drives with
hidden partitions, if they exist. If an unconventional boot fails, the system is reset to
preserve device partition security.
Status Codes Returned
EFI_INVALID_PARAMETER Either the
Attribute
and/or pointers do not match.
