Hi im pretty new to all forms of programming (mostly used to c) well anyway, i thought c was cryptic but asm is something different....

I would like to know what exactly is happening here.....

mov ah,0x0E
mov bh,0x00
mov bl,0x07
mov al,65

int 0x10 //this calls the video interrupt right?

jmp $

ok i know its calling the video interupt and telling it what to do by certain values being in the necessary registers etc but any info would be appreciated as it is somewhat confusing me right now. Anyone know were i might find info on what manipulating these commands will do as i dont wanna mess up a boot sector
