在bochs上运行操作系统返回错误

Question

我正在做一个叫做pintos的操作系统编程项目。它在boch上运行，命令是pintos run nameOfProcess

下面是我得到的错误信息

还有我的bochsrc.txt

romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xe0000  
vgaromimage: file=$BXSHARE/VGABIOS-lgpl-latest
boot: disk

Bochs是在我的Ubuntu11.04上通过额外的配置从源代码构建的

Answer 1

我也有同样的问题，我问了一个question on OSDev forum。我使用file=$BXSHARE/ BIOS -bochs-legacy，因为我需要64K的BIOS。它不适用于：

旧版romimage：

=$BXSHARE/BIOS-bochs-旧版，address=0xf0000

在.bochsrc文件中。而且它没有"address=0xf0000“部分就可以工作。

尝试在此处删除BIOS的起始地址：

最新镜像：

=$BXSHARE/BIOS-bochs- address=0xe0000

只需离开：

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，那么您需要创建一个从"qemu-system-i386“到"qemu”的simbolyc链接。

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

如果qemu的版本低于1.0，则不需要执行此操作。现在，您可以使用qemu运行Pintos，例如：

pintos --qemu -- run alarm-multiple
