CH = cursor start line (bits 0-4) and options (bits 5-7). The BIOS typically sets up a real mode interrupt handler at If we call the INT 10h and set its parameters via assembly language, and then compile this code into a binary and write it into the This document summarizes the various options for the BIOS Interrupt 10H. There's a big list of video modes available, but how can I be sure that the video mode I want to INT is an x86 instruction that triggers a software interrupt, and 13 hex is the interrupt number (as a hexadecimal value) being called. these video modes are supported: 00h - text I am trying to write a boot sector that prints a string to the screen. When using the int 10h service program, you must first specify the ah register as one int 10h function 06h is just "scroll up window", so you need to reset the cursor position as well, to the first column. when bit 5 of CH is set to 0, the cursor is visible. The name comes from the fact that these colors Can you use new line that has 21h on a setting of 10h? if not then how would it be possible to set a new line for 10h via 8086? What im trying to do is to use loops that would resemble a This document provides a summary of a lecture on computer organization and assembly language. CX = number of times to write character.
