Trying to run 32-bit slackware in a virtualbox, but cannot disable vt-x

Hi,

I am trying to run a VM of slackware, but I don't have VT-x support on my computer. So I ran these commands to disable it:

sudo VBoxManage modifyvm Slack --vtxpid off
sudo VBoxManage modifyvm Slack --hwvirtex off

I then tried to run the vm with this command:
sudo VBoxManage startvm "Slack"
But I got this error:
VBoxManage: error: VT-x is not available (VERR_VMX_NO_VMX)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole
