INT 10 - BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. Window Extension v1.1 - SET WINDOW COORDINATES
	AH = 10h
	CH,CL = row,column of upper left corner of window
	DH,DL = row,column of lower right corner of window
Return: AL = status
	    00h successful
	    01h failed
	AH destroyed
Program: BWE is a TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user.  The name comes from the name of the DOS function call used to remain in memory after termination. by John J. Seal published in May 1986 Dr. Dobb's Journal
Note:	when a window has been set, all output via AH=0Eh is restricted to
	  the specified window

INT 10 - VIDEO - Eagle PC2 BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. Rev. C - SET SCROLL SPEED
	AH = 10h
	AL = speed
	    00h fast
	    01h slow (scrolling only moves characters during vertical retrace)
Return: AH = previous speed
                                                                                

INT 10 - Tandy 2000 - VIDEO - GET/SET CHARACTER FONTS                           
	AH = 10h
	AL = control value
	    bit 0: set character set instead of reading it
	    bit 1: high 128 characters instead of low 128 characters
	ES:BX -> new character set if AL bit 0 set
Return: ES:BX -> current character set if AL bit 0 clear on entry
Notes:	this interrupt is identical to INT 52 on Tandy 2000
	the character set consists of 16 bytes for each of the 128 characters,
	  where each of the 16 bytes describes the pixels in one scan line,
	  most significant bit leftmost
