I'm trying to run one of the first stages of James Molloy's kernel tutorial (
http://www.jamesmolloy.co.uk/tutorial_html/) in Bochs on my Archlinux laptop, but when I unleash Bochs onto the image, it gave me an error message. I tweaked the configuration file, read the manual, googled the problem and then I thought it might be a problem with the build from the Arch repos.
I downloaded the source code for the latest stable version and then did:
Code:
$ ./configure --with-x11 --with-sdl --enable-x86-64
$ make
I ran the executable with
Code:
$ /source/directory/bochs -f bochsrc.txt
With this bochsrc.txt
Code:
megs: 32
romimage: file=/usr/share/bochs/BIOS-bochs-latest address=0xf0000
vgaromimage: file=/usr/share/bochs/VGABIOS-elpin-2.40

log: bochsout.txt
mouse: enabled=0
clock: sync=realtime
cpu: ips=5000000 model=corei7_sandy_bridge_2600k

I get the following output:

Bochs Configuration: Main Menu
------------------------------
This is the Bochs Configuration Interface, where you can describe the
machine that you want to simulate. Bochs has already searched for a
configuration file (typically called bochsrc.txt) and loaded it if it
could be found. When you are satisfied with the configuration, go
ahead and start the simulation.
You can also start bochs with the -q option to skip these menus.

SDL works fine for other programs and X appears to work. Does anyone know of a solution?
