Hi All Sorry this is a bit of a new area for me, I've tried to read up but there's a lot to try to absorb quickly. I have a Dell Laptop which I run Fedora x86_64 on as the primary OS, I occasionally need to use Win 7 on it (which it's licensed for) however the Dell restore disk won't register properly in a VM so I have to run dual boot which is a pain. Reading the forums I think I need.... A Dell VMware BIOS with SLIC 2.1? Which I then tell the VMWare host to use that BIOS instead of it's default one I assume via a setting in a config file somewhere? I should then be able to install my genuine Dell Win 7 Pro and it'll register properly? Can I use the same VMware BIOS on my desktop machine if I need to run a temporary test environment? If someone could point me at either an existing BIOS or even better at instructions how to make my own BIOS (so I learn more) I'd be very grateful. Thanks all.
