Operating Systems, Spring 2020

OpSys-Spr2020

This is the code for an operating system that was being written during spring 2020. Unfortunately covid hit and the lab had to be changed due to working remote. -Josh

Lab01 clearScreen function: Using a for loop that loops through 24 times, we were able to implement 24 carriage return character and 24 newline character using these interrupt 16.

printScreen function: To decide which path we wanted our char string to go, we used an if/else path. If the parameter that was passed into D was a 1, then it would print our char string to the print.out file, else it would print to the display. We did this with two different interrupts (16 , 23).

Interrupt 33/handleInterrupt21: In this function, we used a switch statement that would take in the parameter from the initial interrupt 33 in main. Currently we have only one switch case (0) for which we call the printString function and pass the char string and parameter for D. We also have a default case for any error case errors.

Additionally, an additional script, runOS.sh, is included to invoke the Bochs emulator as a shortcut.
