bochs安装配置_哔哩哔哩_bilibili

上面video也是按照这个步骤

nasm boot.asm -o boot.bin
dd if=boot.bin of=a.img  bs=512 count=1

organe's一个操作系统实现实验一实验步骤_哔哩哔哩_bilibili

# filename of ROM images
romimage: file=/usr/local/share/bochs/BIOS-bochs-latest
vgaromimage: file=/usr/local/share/bochs/VGABIOS-lgpl-latest

# enable key mapping, using US layout as default.
for ubuntu
keyboard:  keymap=/usr/local/share/bochs/keymaps/x11-pc-us.map
for macos
keyboard: keymap=/usr/local/share/bochs/keymaps/sdl2-pc-us.map

macos

./configure --prefix=/usr/local \
--enable-smp \
--enable-cpu-level=6 \
--enable-disasm \
--enable-x86-64 \
--enable-vmx=2 \
--enable-svm \
--enable-all-optimizations \
--enable-debugger \
--enable-debugger-gui \
--with-sdl2

If SDL2 fails, try:
–with-sdl

Build

make

(This may take several minutes.)

Install

sudo make install

error

2) Find the line around ~194

You’ll see something like:

char *devname; ... if ((devname = strrchr(devpath, '/')) != NULL) {

3) Change devname to const char *

Edit it to:

const char *devname; ... if ((devname = strrchr(devpath, '/')) != NULL) {

保护模式

实验a运行

需要代码自带的 a.img,因为 pmtest1.asm 没有55aa,自己创建的找不到盘

nasm pmtest1.asm -o pmtest1.bin
dd if=pmtest1.bin of=a.img bs=512 count=1 conv=notrunc

实验b

nasm pmtest2.asm -o pmtest2.com

sudo mkdir /mnt/floppy
sudo mount -o loop pm.img /mnt/floppy
sudo cp pmtest2.com /mnt/floppy
sudo umount /mnt/floppy


sudo mkdir /Users/m/floppy
sudo mount -o loop pm.img /Users/m/floppy
sudo cp pmtest2.com /Users/m/floppy
sudo umount /Users/m/floppy

//到b磁盘下
b:
//运行
