using the bootstrap loader

3.3.4 %AGAIN Macro
CONFIGURING THE FIRST STAGE
The %AGAIN macro causes the bootstrap loading sequence to return to the beginning of
the first stage whenever a bootstrap loading error occurs. You should include this macro if
you include the %CONSOLE macro in the BSERR.A86 file, either directly or by including
the %TEXT or %LIST macro.
The syntax of the %AGAIN macro is
%AGAIN
Exactly one of the %AGAIN, %INT1, %INTI, and %HALT macros must be included, or
an error will occur when BSERR.A86 is assembled.
3.3.5 %INT1 Macro
The %INTl macro causes the Bootstrap Loader to execute an INT 1 (software interrupt)
instruction whenever a bootstrap loading error occurs. This macro useful for passing
control to the D-MON386 monitor. The iSDM monitor does not support this macro.
The syntax of the %INTl macro is
%INTl
There are no parameters associated with this macro.
Exactly one of the %AGAIN, %INT1, %INTI, and %HALT macros must be included, or
an error will occur when BSERR.A86 is assembled.
3.3.6 %INT3 Macro
The %INTI macro causes the Bootstrap Loader to execute an INT 3 (software interrupt)
instruction whenever a bootstrap loading error occurs. If you are using the iSDM monitor,
the INT 3 instruction passes control to the monitor. Otherwise, the INT 3 instruction has
no effect unless you have placed the address of your custom interrupt handler in position 3
of the interrupt vector table.
The syntax of the %INTI macro is
% INTI
There are no parameters associated with this macro.
Exactly one of the %AGAIN, %INT1, %INTI, and %HALT macros must be included, or
an error will occur when BSERR.A86 is assembled.
