A

    B

      C

      • creg_str.npp - Convert REGister in STRing: this procedure converts the content of BX into the corresponding ASCII code and stores it in the memory location pointed by ES:[DI].
      • CheckTTW.zip: this is the small project that tests INT 10h/AH=0Eh on the different video pages in real mode x86. I presented this project in the post "Check Teletype Write".

      D

        E

          F

            G

              H

              • hand_lnk.npp - HAND LiNKing: this procedure builds a test environment for different service procedures and shows a method to link procedures together in an incremental growing software.

              I

                J

                  K

                    L

                    M

                    • make_shuttle2.npp: this is the code that manipulates SHUTTEMP (template of SHUTTLE2) to produce the customized version of SHUTTLE2 that is going to boot on the target PC.

                    N

                    • nbl_asc.npp - NIBble to ASCii: this function converts the low nibble of AL (bit 3 to 0) in the corresponding hexadecimal code.

                    O

                    • out_nbl.npp - Out a nibble: this procedure returns in AL (bit0 to bit3) the value of the selected nibble in BX. The selection is done depending on the value in CX.

                    P

                      Q

                        R

                        • RW_LBA.npp alias read_write_LBA: This procedure reads from or writes to disk with LBA technique.

                        S

                        • Scroll.zip: this is the small project that tests the scroll upwards and downwards in combination with the different video modes in real mode x86. I presented this project in the post "Scroll up and down".
                        • scroll_test.zip: this is the small project that writes directly in Video RAM to create an active scrolling effect. I presented this project in the post "Video Scroll (part I)".
                        • show_str.npp - SHOW STRing: this function shows a string on the video starting at address DS:[SI] and terminating as soon as the function finds the byte 0x00.
                        • show_string_II.npp: this procedure shows a string on the video starting at address DS:[SI] and terminating as soon as the function finds the byte 0x00. This procedure preserves the registers used.
                        • shuttemp.npp: this is the template for the SHUTTLE2 boot Software. It creates the boot software, but leaves the BIOS Parameter Block and the LBA Packets undefined.

                        T

                        • TEST_LBA.npp: this procedure checks that it is legal to call INT 13H with AH = 0x42 (LBA Read) and AH = 0x43 (LBA Write)
                        • test_SHUTTLE2.npp: this is a test for SHUTTLE2. It produces a SOFTWARE.BIG which is larger than a single cluster.

                        U

                          V

                          • volume_rename.npp: This procedure renames the volume label entry in the ROOT directory, changing it in "GOOD RENAME".

                          W

                          • write_ASCII.npp: this procedure converts the content of BX into the corresponding ASCII code and stores it in the memory location pointed by ES:[DI]. CX is used to control the portion of BX to be converted in ASCII.

                          X

                            Y
