The file is incorrect.
Common bochsrc:

Next, in the second chapter of "Implementation of an orange OS" about modifying the content of the bochsrc configuration file:

After installing bochs, We need to configure bochs. In fact, we need to modify the bochrsc file!

The attached CD of Orange's: Implementation of an operating system contains a configured bochrsc,
Yes. It is for bochs2.3, so it cannot be used !!! We need to modify bochrsc again!
First, move the folder A under the Chapter1 subdirectory in the attached CD to/home/roothoo/(mainly
Is to make a. IMG and bochsrc in the same folder), and then modify bochrc as follows:
Note: # Is the annotator! That is, # the subsequent statement is invalid. In fact, # is equivalent to // in C + //
######################################## #######################
# Configuration file for bochs
######################################## #######################

# How much memory the emulated machine will have
Megs: 32

# Filename of ROM images
# Romimage: file =/usr/local/share/bochs/BIOS-bochs-Latest
Romimage: file = $ bxshare/BIOS-bochs-Latest

# Vgaromimage:/usr/local/share/vgabios. Bin
Vgaromimage: file = $ bxshare/vgabios-lgpl-Latest

# What disk images will be used
Floppya: 44 = A. IMG, status = inserted

# Choose the boot disk.
Boot: floppy

# Where do we send log messages?
# Log: bochsout.txt

# Disable the mouse
Mouse: enabled = 0

# Enable key mapping, using us layout as default.
Keyboard_mapping: enabled = 1, map =/usr/local/share/bochs/keymaps/x11-pc-us.map

Pay attention to the two sentences in red!

After modification, do not forget to save it!
Finally, we run bochs
CD/home/roothoo/A # Switch to the folder where a. IMG and bochsrc are located,
Bochs-F bochsrc # Start bochs with bochsrc as the configuration file
Then select 6,
Then press the C key,
OK !!!
Enjoy! -_-
