Qemu 在 Windows 上運行時無法加載 bios-256k.bin (Qemu can't load bios-256k.bin when running on Windows)

問題描述

Qemu 在 Windows 上運行時無法加載 bios‑256k.bin (Qemu can't load bios‑256k.bin when running on Windows)

我試圖在 Windows 操作系統上測試 qemu，當我嘗試使用以下命令啟動 ubuntu iso 時：

qemu‑system‑x86_64.exe ‑boot d ‑cdrom .\ ubuntu‑20.04.1‑desktop‑amd64.iso ‑m 2048

然後我得到以下錯誤：

qemu: could not load PC BIOS' bios‑256k.bin'

在Enviroment Varibles中設置了Qemu文件夾，並且bios‑256k.bin文件在文件夾中我該如何解決這個問題？

參考解法

方法 1:

Add an option for bios file directory entry with ‑L switch. Your command should look like this:

qemu‑system‑x86_64.exe ‑boot d ‑cdrom .\ubuntu‑20.04.1‑desktop‑amd64.iso ‑m 2048 ‑L "C:\Program Files\qemu"

Of course in case your default qemu installation is in C:\Program Files\qemu and bios files are inside that directory. For some reason, qemu has a bug that doesn't search bios files in defined path and look for them in current working directory.

Edit: I found a bug report that mentions this issue. It also seems to be fixed in newest version. Anyway, here is the link: https://bugs.launchpad.net/qemu/+bug/1915794

This is a known and documented problem with a simple workaround: "Known issue: currently requires start from installation directory or ‑L option to specify the location of the firmware files."

And it is already fixed in the newer installer.
