在 bochs 上运行操作系统返回错误

Question

我正在研究一个名为 pintos 的操作系统编程项目。它按照命令在 bochs 上运行pintos run nameOfProcess

这是我收到的错误消息

还有我的 bochsrc.txt

Bochs 是从源代码构建的，在我的 Ubuntu 11.04 上有额外的配置

我遇到了同样的问题，我在 OSDev 论坛上问了一个问题。我使用 file=$BXSHARE/BIOS-bochs-legacy 因为我需要 64K BIOS。它不适用于：

romimage：文件=$BXSHARE/BIOS-bochs-legacy，地址=0xf0000

在 .bochsrc 文件中。它无需“address=0xf0000”部分即可工作。

尝试在这里删除BIOS的起始地址：

romimage：文件=$BXSHARE/BIOS-bochs-latest，地址=0xe0000

走吧：

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

在你的 bochsrc.txt
