  I have implemented a process_table struct with id, status, and block_size. I
  have also made the appropriate lists and iterators for those lists.

  In reboot I set the struct for the idle process and and then do the
  mem_store(pc_register, idle_start); command. but I get an error:
  
    "not a valid system call 0" (which is the default panic at the end of my
    sys_call_ih function)
    fatal system error: unknown interrupt 20 in interrupt handler()

The PC is part of a process's state, but is it the only part? You might want
to review the CPU Register Set section in the hardware-architecture page.
