INT 10h / AH = 09h - write character and attribute at cursor position. INT 10h / AH = 08h - read character and attribute at cursor position. INT 10h / AH = 05h - select active video page.ĪL = number of lines by which to scroll (00h = clear entire window).īH = attribute used to write blank lines at bottom of window.ĬH, CL = row, column of window's upper left corner.ĭH, DL = row, column of window's lower right corner. INT 10h / AH = 03h - get cursor position and size. otherwise wrong cursor shapes are displayed. note: some bioses required CL to be >=7, show box-shaped blinking text cursor: mov ch, 0 show standard blinking text cursor: mov ch, 6 When bit 5 is 1, the cursor is not visible. When bit 5 of CH is set to 0, the cursor is visible. INT 10h / AH = 01h - set text-mode cursor shape.ĬH = cursor start line (bits 0-4) and options (bits 5-7). The short list of supported interrupts with descriptions:Ġ0h - text mode. Windows XP may overwrite some of the original interrupts.
X86, original Intel 8086 and AMD compatible microprocessors, however These interrupts should be compatible will IBM PC and all generations of 8086 bios and dos interrupts (IBM PC) The list of all interrupts that are currently supported by the 8086 assembler emulator.
