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 SeeAlso: AH=11h"Window",AH=12h"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 SeeAlso: AH=00h,AH=0Bh/BH=02h,AH=11h"Tandy 2000",AH=12h"Tandy 2000" SeeAlso: INT 52"Tandy 2000"
