To move the cursor, I use the INT 10h function 2h (AH = 2h). To print a string, I use the INT 10h function 0Ah (AH = 0Ah).

Now, I will explain how to print a string, read sectors, and wait for a key press using only the BIOS.

Now, I will explain the basics of a boot program (to understand this, you need to be familiar with Assembler and Interrupts and Interrupts vector table). Move the read pointer to the right sector. NULL) // if(hDrive=INVALID_HANDLE_VALUE) // if Error Openning a drive.
#Tutorial c builder w7 driver#
Init the drive name (as a Driver name). // pBuffer has to be at least 512 bytes wide.īOOL ReadSector( char chDriveName, char *pBuffer,DWORD nSector)
#Tutorial c builder w7 code#
You can read raw sectors from a drive like this:Ĭopy Code // // Reading/writing raw sectors. Press u (u = unassemble) to unassemble the file.

The Debug command starts a 16 bit debugger (any boot sector is in 16 bit code, because when the computer starts, it is in 16 bit mode, and only after the boot sector is run, can it change the CPU to 32 bit mode or 64 bit mode). With BOOTSectorUtility.exe, you can also search your regular operating system, by saving the boot sector of the drive of your operating system to a file.Īnd to read that file, start the command line and type Debug (if you have a Microsoft operating system). Restart your computer (make sure that the floppy diskette is in the drive), and watch what our BOOT sector does.Make sure that your BIOS is set to BOOT from the floppy drive first, so that our operating system would be loaded.Use the program that comes with this article, BOOTSectorUtility.exe, to copy the file BOOT.bin to the floppy diskette BOOT sector.Take a floppy diskette that you don't need.Now this little program that was loaded from the BOOT sector continues to load the operating system, and after the operating system is loaded, it initializes the operating system and gives the control to the operating system.(A disk is divided into little regions that are named sectors. The BOOT sector size is 512 bytes in most drives.) If the drive has a valid BOOT sector, the BIOS loads that sector in to the memory at address 0:7c00 (=31,744) and gives control to that area of the memory. The BIOS checks the first drive to see if he has a valid BOOT sector.

And also look up (if you don’t now how to do it) how to change the search search of BIOS while looking for an operating system.) To get to the BIOS setup, right when the computer turns on, press the DELETE key until you see the BIOS setup program in some computers, it can be a different button than DELETE, so look in your mother board specification to find how to get to the BIOS setup program. The order the BIOS checks can be set it in the BIOS setup program. (The BIOS can look in hard drives, floppy drives, CD-ROM drives etc.

In this article, I would explain the first part of building an operating system. You would also learn from this article how to read and write raw sectors from a disk. And also, I'm sure every one would like to have their own operating system.
