Question

我正在开发一个名为pintos的OS编程项目。它在命令pintos run nameOfProcess

之后在bochs上运行

这是我收到的错误消息

Bochs是在我的Ubuntu 11.04

上使用额外配置从源代码构建的

Answer 1

我遇到了同样的问题，我问了question on OSDev forum。我使用file = $ BXSHARE / BIOS-bochs-legacy因为我需要64K BIOS。它无效：

romimage：file = $ BXSHARE / BIOS-bochs-legacy，address = 0xf0000

<。>在.bochsrc文件中。它没有“address = 0xf0000”部分。

尝试删除BIOS的起始地址：

romimage：file = $ BXSHARE / BIOS-bochs-latest，address = 0xe0000

离开：

romimage：file = $ BXSHARE / BIOS-bochs-latest

在你的bochsrc.txt
中

Answer 2

安装qemu而不是bosch：

sudo apt-get install qemu

如果qemu的版本是最近的，那么你需要创建一个从“qemu-system-i386”到“qemu”的simbolyc链接

sudo ln -s /usr/bin/qemu-system-i386 /usr/bin/qemu

如果qemu的版本小于1.0，则不需要这样做。现在您可以使用qemu运行Pintos，例如：

pintos --qemu -- run alarm-multiple

在bochs上运行OS返回错误
