INT 10 - VIDEO - TEXT-MODE CHARGEN - LOAD USER-SPECIFIED PATTERNS (PS,EGA,VGA)

	AX = 1100h
	ES:BP -> user table
	CX = count of patterns to store
	DX = character offset into map 2 block
	BL = block to load in map 2
	BH = number of bytes per character pattern
Return: nothing
Notes:	This function will cause a mode set, completely resetting
	  the video environment, but without clearing the video buffer
	the current block specifiers may be determined with INT 10/AH=1Bh,
	  looking at offsets 2Bh and 2Ch of the returned data (VGA only)
	  (see AH=1Bh,#00040)
