I want to have Bochs setup for when I actually start writing code, so I assembled the bootable code from Babysteps 1 and made it into an img file. I then followed all the tutorials I could, but I cant get Bochs to boot the file. Help?

whats the error?

C:\Program Files (x86)\Bochs-2.4.5\bochsrc.bxrc:596: a bochsrc option needs at least one parameter

May I point you to the forum rules. Specifically #4 (and to a lesser extent, #3)

To be of any help, we need to know what you did, how it failed, and what you have already tried.
Posting your compilation commands and source usually helps.

[EDIT] I emphasise rule 3 now that I have seen your problem.

Sorry if I'm not much help in providing info, I'm just not familiar with using an emulator to test my stuff.

This is my bochsrc.bxrc file. When I open Bochs, I click Load, select the file, and try to run the emulation. I get said error, and then I kill the emulation.

@a549 nothing. Well, there was, but I tried a different, shorter version of the bochsrc-sample. I'm probably wrong, but is 596 an error code maybe?

use lba trnaslation ald align YOUR ENTIRE FILE to 20*16*63*512 if you use first one.
solved?

and try running bochs from command line or script. Save a lot of time if you compile and run bochs at single key press.
