1 Lecture (09) x86 programming 8 By: Dr. Ahmed ElShafee 1 Basic Input Output System BIOS BIOS refers to a set of procedures or functions that enable the programmer have access to the hardware of the computer. A BIOS function is invoked using the instruction. The actual function is specified by the contents of AH. ROM BIOS refers to BIOS procedures that are stored in a ROM placed on the motherboard. Some typical ROM BIOS are: 10H Video Driver 13H Disk Driver 14H Serial Port Driver 16H Keyboard Driver DOS BIOS refers to BIOS that are loaded from a disk after the computer is booted up. Most DOS BIOS are invoked using the 2 instruction.
2 Character Input from keyboard with Echo: Function 01H: Call With: AH = 01H Returns: AL = ASCII character pressed. Note: If AL is zero, then a function key is pressed. Example: The following macro reads a one digit number from the keyboard and returns the corresponding binary value in AL. AH,01 ;Specify function 01 ;Call DOS BIOS 3 Display Character on Standard Output Device Function 02H: Call With: AH = 02H DL = ASCII code of character to be displayed Returns: AL = ASCII code of character displayed Note: Standard output device is normally the monitor. Example: The following macro displays a one digit number on the screen. The number is passed in DL as a binary number. 4 add DL,30H ;Convert from binary to ASCII AH,02 ;Specify function 02 ;Call DOS BIOS
3 Display a Character String Function 09H: 5 Call With: AH = 09H DS:DX = Segment:Offset address of the string. Returns: All registers unchanged. Note: Displays a character string up to the first occurrence of the dollar sign "$". Example: The following macro displays the character string MSG on the screen. DMSG MSG DX, Offset MSG ;Point to MSG AH,09 ;Specify function 09 ;Call DOS BIOS DMSG Buffered Keyboard Input Function 0AH: 6 Call With: AH = 0AH DS:DX = Segment:Offset address of the buffer The first byte in the buffer should be loaded with the size of the buffer, i.e. the maximum numberof characters to be input. Returns: All registers unchanged. The second byte in the buffer is equal to the number of characters entered. The characters entered are stored in the buffer starting from the third byte. Note: The functions ends if the user has typed in a number of characters equal to the first value in the buffer, or if the user has pressed the Enter key.
4 The following procedure prompts the user to type in a text up to 30 characters long. The text entered is stored in the buffer BUF1. The procedure uses the DSPM macro of the previous example. 7 ORG 100H MSG1 DB Type in a text up to 30 characters long, 0AH, 0DH, $ BUF1 DB 30, 00, 30 DUP(?) MAIN PROC NEAR DSPM MSG1 ;Display MSG1 DX, Offset BUF1 ;Point to BUF1 AH,0AH ;Specify function 0A ;Call DOS BIOS RET MAIN ENDP Example 01 ORG 100H jmp MAIN MSG1 DB "Type in a text up to 30 characters long", 0AH, 0DH,'$' BUF1 DB 30, 00, 30 DUP(?) MSG2 DB "press any key to continue,..$" ADD DL,30H AH,02 DMSG DMSG MSG DX, Offset MSG AH,09 AH,01 8
5 MAIN PROC NEAR DMSG MSG1 DX, Offset BUF1 AH,0AH DMSG MSG2 RET MAIN ENDP 9 10
6 11 Example 02 ORG 100H jmp MAIN MSG1 DB "Type in a text up to 30 characters long", 0AH, 0DH,'$' BUF1 DB 30, 00, 30 DUP(?) MSG2 DB "press any key to continue,..$" DMSG MSG DX, Offset MSG AH,09 ADD DL,30H AH,02 DMSG AH,01 12
7 GET2 GET2 BUF DX, Offset BUF AH,0AH MAIN PROC NEAR DMSG MSG1 GET2 BUF1 DMSG MSG2 RET MAIN ENDP 13 ASCII Codes ASCII code is a standard 8-bit binary code for alphanumeric characters. It defines: a group of control characters (00H to 20H and 7FH for Delete) a group of printable characters ( to 7EH) a group of special graphics or multilingual characters (80H to FFH) ASCII Control Characters 00 NUL 01 SOH 02 STX 03 ETX 04 EOT 05 ENQ 06 ACK 07 BEL 08 BS 09 HT 0A LF 0B VT 0C FF 0D CR 0E SO 0F SI 10 DLE 11 DC1 12 DC2 13 DC3 14 DC4 15 NAK 16 SYN 17 ETB 18 CAN 19 EM 1A SUB 1B ESC 1C FS 1D GS 1E RS 1F US 14 BIOS
