ARMA Dedicated in a VM

I've been trying to setup a dedicated ARMA (Armed Assault) server in a Virtual Machine. I made the mistake of attempting to use MS Virtual PC 2007 initially. ARMA installed and then I went through the labourious 1.5 GB worth of patching (up to v 1.08) ok in Virtual PC, but running the dedicated server executable generated an error that I was running an unsupported operating system. I think this is because the disks in Virtual PC 2007 are attached as SCSI disks and it causes a Securom issue (Grrrr!).

Installing, patching and executing the ARMA dedicated server in VMWare Server 1.0.5 presented no problems. VMWare presents the disks as IDE, this is what makes me think it is Securom that is causing the problem.
