F_INS_FREEGLBDS (AH
=
16H)
Installs a vector in the next free entry of the HP_VECTOR-TABLE and calls it with an SF_INIT
function. When F_INS_FREEGLBDS calls the initialization routine it passes the data segment of
the EX-BIOS global data area in the BX register.
Warning
If the SF_INIT function returns with an error code of RS_FAIL (OFEH) the power-on
self test sequence will be executed.

This function is used to search the HP_VECTOR-TABLE for drivers that have equal or similar
values in a specified field of their data segment. Parameters passed to the function specify the
location of the 16-bit field, the bits within the field to be compared (and_mask) and the pattern
of bits the field is to be compared with. Given a starting vector address, the function searches
the vector table for the next driver that matches the conditions specified and returns its vector
address in SI.
