Fixing Debugger Malfunction on 8088 Microprocessors

SUMMARY

The discussion centers on a malfunctioning debugger while working with 8088 microprocessors. The user reports that the Advanced Full Screen Debugger v2.0 on Windows Vista fails to display changes in register values during code execution, despite the NASM assembler functioning correctly. The user is uncertain whether they are using an 8086 or 8088 processor but confirms that the debugger operates properly on the 8088. The consensus suggests the need for a different debugger compatible with assembly language for better functionality.

PREREQUISITES
  • Understanding of x86 architecture and its registers
  • Familiarity with NASM assembler
  • Knowledge of debugging tools and their compatibility with target architectures
  • Basic experience with Windows Vista operating system
NEXT STEPS
  • Research alternative debuggers for assembly language, such as GDB or OllyDbg
  • Learn about the differences between 8086 and 8088 microprocessors
  • Explore advanced debugging techniques for x86 architecture
  • Investigate compatibility issues between debuggers and specific processor types
USEFUL FOR

Assembly language programmers, software developers working with x86 architecture, and anyone troubleshooting debugger issues on 8088 microprocessors.

Debugger don't work

I downloaded and extracted assembler and debugger in the same folder. But debugger is not showing corresponding registry value changes for actual code.
nasm assembler works fine.
are debuggers only suppose to work for 8088 microprocessors?

"Registry" or "register"?

Can you be more specific? What target architecture are you assembling and debugging? I assume the machine you're using is x86 or x86-64? Which "debugger" are you using? "Debugger" could mean a number of things but I would normally expect a debugger to only run programs written for the same target architecture the debugger itself as an executable is written for.
 
It's register. I am using T2310 processor 32 bit.
In the code if I move the cursor to instruction
mov ax, 10 then the debugger is suppose to show that the value 10 is moved to register ax.
when I move the cursor to add ax, bx debugger is suppose to show corresponding changes but it's not showing those changes. The register values remain zeros no matter where I move the cursor.
I am using advanced full screen debugger v 2.0 on vista. I don't know if I am using 8086 or 8088 processor but the debugger is working fine on 8088 processor. I think I have to use a different debugger. What do you think? Where to find another debugger for assembly language? I am using Nasm.
I downloaded the tools from
