The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Read/Write to FAT12 floppy, output to screen.

Asked by raven31337 in Assembly Programming Language

Tags: fat12, tasm, floppy, read

I have read literaly 50 tutorials on int 13h for disk i/o and int 10h for changing screen mode and even more on FAT12. I have tried to put it all together into one program and it just doesnt like me. This is for an operating system I am trying ot build from scratch. So far I have been able to:
-reset the drive
-read to a buffer (! have slight prroblem accessing the data once it is in the buffer)

-print a hard coded string of test.
-change video modes

What I want to be able to do is have my program

read from the disk.
store it in a buffer.
output the buffer to the screen.
hang, die, crash, w/e

at the moment I am not looking for this to be bootable. I do not want to use DOS interupts because they just wont work when I go to make it bootable.
(i have tasm and nasm)

I would appreciate any help.
thanks in advance,
-Ken
