In the process of finding out information, and some said 13 h int the MBR program loaded into memory, others said, after the completion of the BIOS self-built produce int 19 h, reads a boot partition to 00:7 C memory, program executes a jump to 00:7 C,,,,
I know int 13 h has the ability to read disk, when does int 19 h program calls the int 13 h interrupt to perform the process of reading the disk?

CodePudding user response:

Int 19 interrupt some, choose in what equipment start system, int 13 interrupt to read disk must be true
