VirtualBox on Scientific Linux

Installed it yesterday and copied my battered but always faithful Win2K vdi image.
Basically it was following the instructions here:
Install VirtualBox on CentOS / Scientific Linux

Everything went Ok, but I had to make two changes on the settings to make it work on my T43.
The first one was to disable IOAPIC to make it actually boot (the screenshot above) the other one was to set the network to NAT (even tho the Win2K adapter has and always had a fixed IP address).

$ sudo yum install dkms
$ sudo wget -P /etc/yum.repos.d http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo
$ sudo yum install VirtualBox-4.1
$ sudo usermod -a -G vboxusers your_user_name
