Table 66 defines the bitmap for each scan point, indicating when the scan point occurs and which resources are available (RAM, stack, binary data area, video, keyboard).

Table 66. User Binary Area Scan Point Definitions

Scan Point	Mask	RAM/Stack/BDA	Video/Keyboard
Near the pointer to the user binary extension structure. The mask bit	01h	Not applicable	Not applicable
is 0 if this structure is not present. Instead of a jump instruction, the
scan address (offset 5) contains a 0CB followed by a near pointer.

Obsolete, no action taken.	02h	Not applicable	Not applicable

This scan occurs immediately after video initialization.	04h	Yes	Yes

This scan occurs immediately before video initialization	08h	Yes	No

This scan occurs on POST error. On entry, BX contains the number of	10h	Yes	Yes
the POST error
This final scan occurs immediately prior to the INT 19 for normal boot	20h	Yes	Yes
and allows one to completely circumvent the normal INT 19 boot if
desired.
