Total Marks: 20

 

Due Date:

May 10, 2018

 

Instructions:

 

Please read the following instructions carefully before submitting assignment. It should be clear that your assignment will not get any credit if:

 

§  The assignment is submitted after due date.

§  The submitted assignment does not open or file is corrupt.

§  You have not followed steps described in Detailed Instructions of the problem statement.

§  Assignment is copied (partial or full) from any source (websites, forums, students, etc.) Strict action will be taken in this regard.

 

Note: You have to upload only .doc or .docx file. Assignment in any other format (extension) will not be accepted and will be awarded with zero marks.

 

Objectives:

 

The objective of this assignment is to provide hands-on experience of System Programming concepts including:

 

·         Interrupts

·         Generating interrupts

·         Writing our own interrupt functions

·         Making a Terminate and Stay Resident (TSR) program

·         Accessing monitor text memory area

·         Taking input from user and invoking relevant interrupt functions

 

Lectures Covered:

 

This assignment covers lecture # 1 to lecture # 6

Problem Statement:

 

Write a TSR (Terminate and Stay Resident) program, by using interrupt 65H, that will print Student ID when 0 is pressed by the user, and full Name when 1 is pressed by the user.

 

Detailed Instructions:

1)      In this program, you will implement interrupt 65H which is currently not used by operating system.

2)      Interrupt 65H function must check for Service Number – if service number is 0, your Student ID will be printed and if service number is 1, your full Name will be displayed. In order to implement this, place service number in AH register. Interrupt 65H will check its value and will perform relevant function.

3)      Student ID or full Name must be printed at the beginning of monitor text memory area, 0xb8000000

4)      Calculate Attribute Byte for both Student ID and Name according to the following criteria:

a.       Text blinking: No

b.      Background color: White

c.       Foreground color: Black

d.      Bold text: No

5)      Visit this link: https://ascii.cl/ for complete ASCII table. This table is also available in the Downloads section of LMS.

6)      Use keep() function to make this program TSR.

7)      After writing interrupt 65H, write a test function which will take input from user (for example: Enter 0 for printing Student ID and 1 for printing Name), place relevant service number in AH register, and generate interrupt function. You may use switch statement for this.

8)      Your assignment file should be a single Word file (.doc or .docx) containing:

a.       Complete interrupt function (both services must be implemented)

b.      Test function to generate interrupt as given in instruction # 7

9)      You can use Consolas font for enhancing readability of the code in Word file.

Note:

You should NOT use interrupt 21/09H to display Student ID or Name. It must be displayed only by accessing monitor text memory area.

Best of Luck!

or isko kis formate ma submit krna ha plz bat day

Detailed Instructions:
1) In this program, you will implement interrupt 65H which is currently not used by operating system.
2) Interrupt 65H function must check for Service Number – if service number is 0, your Student ID will be printed and if service number is 1, your full Name will be displayed. In order to implement this, place service number in AH register. Interrupt 65H will check its value and will perform relevant function.

04 - TSR programs and Interrupts
Another Example:
#include<BIOS.H>
#include<DOS.H>
char st[80] ={"MC******$"};
char st1[80] ={"Iqra Hadayat!$"};
void interrupt (*oldint65)( );
void interrupt newint65( );
void main()
{
oldint65 = getvect(0x65);
setvect(0x65, newint65);
keep(0, 1000);
}
void interrupt newint65( )
{
if (( _AH ) == 0) //corrected
{
_AH = 0x09;
_DX = (unsigned int) st;
geninterrupt (0x21);
}
else
{
if (( _AH ) == 1) //corrected
{
_AH = 0x09;
_DX = (unsigned int) st1;
geninterrupt (0x21);
}
}
}
Various interrupts provide a number of services. The service number is usually placed in
the AH register before invoking the interrupt. The ISR should in turn check the value in
AH register and then perform the function accordingly. The above example exemplifies
just that. In this example int 65 is assigned two services 0 and 1. Service 0 prints the
string st and service 1 prints the string st1. These services can be invoked in the
following manner.
#include<BIOS.H>
#include<DOS.H>
void main()
{
_AH = 1;
geninterrupt (0x65);
_AH = 0;
geninterrupt (0x65);
}

first two iinstructions k lie y search ki h m n 

comments please 

also tell me 21/09 instruction use nhi krni last p mention kia sir n esa kion

plz mere pass sotware nahi he aur aaj extenday plz aap muje send kr dein my gmail id Arsalmalik335@gmail.com he
