How does INT 10, 13h work with attributes?
Hey Im trying to understand the INT 10h, 13h (19) that writes a Character String with the BIOS interruption 10 with 13h in ah. I have found the info below about the different flags to put in the the different registers. One thing I still don't get is what is supposed to go in BL, if i simply want to write a string with this function what should be in BL as attribute? Right now it writes out strange blinking symbols that don't make sense. Thank you, beforehand Writes a string of characters with specified attributes to any display page.
