VirtualBOXでのWindows2000のインストールについて

Oracle VM VirtualBOXでWindows2000を入れようとすると、
ネットワークのコンポーネントインストール時にリブートがかかり、
その先に進めず、インストールができない。

これは、Windows2000のHDDドライバのバグで、
ヘルプファイルの12．3.3にも記載されている。

回避方法は、Dosプロンプトから、以下のコマンドを実行する。
DOS
cd C:\Program Files\Oracle\VirtualBox
VBoxManage setextradata "win2k" "VBoxInternal/Devices/piix3ide/0/Config/IRQDelay" 1
↑VirtualBOX設定ファイル名

ここまで

12.3.3. Windows 2000 installation failures
When installing Windows 2000 guests, you might run into one of the following issues:

Installation reboots, usually during component registration.

Installation fills the whole hard disk with empty log files.

Installation complains about a failure installing msgina.dll.

These problems are all caused by a bug in the hard disk driver of Windows 2000. After issuing a hard disk request, there is a race condition in the Windows driver code which leads to corruption if the operation completes too fast, i.e. the hardware interrupt from the IDE controller arrives too soon. With physical hardware, there is a guaranteed delay in most systems so the problem is usually hidden there (however it should be possible to reproduce it on physical hardware as well). In a virtual environment, it is possible for the operation to be done immediately (especially on very fast systems with multiple CPUs) and the interrupt is signaled sooner than on a physical system. The solution is to introduce an artificial delay before delivering such interrupts. This delay can be configured for a VM using the following command:

VBoxManage setextradata "VM name"
"VBoxInternal/Devices/piix3ide/0/Config/IRQDelay" 1
This sets the delay to one millisecond. In case this doesn't help, increase it to a value between 1 and 5 milliseconds. Please note that this slows down disk performance. After installation, you should be able to remove the key (or set it to 0).
