We’ve had a huge headache at work because all our testing machines use a custom OEM bios. This allows MS Windows and SQL activations to happen transparently. Dell does this, and it is incredibly convenient when you are their customer. When you are the OEM and using VMware it is a little tricky. You can load a custom bios in a VM by adding a line to the VMX file. We used to have a scripted copy that sent the bios to each and every VM directory. This would be cumbersome because the script took a while to run, and it breaks Storage vMotion. The entry looks like this:
bios440.filename = “OEM_Bios.rom”
A while ago I realized that specifying a full path works like this:
bios440.filename = “/vmfs/volumes/Datastore_Name/OEM_Bios.rom”
Lab Manager is very grateful for this change especially because XP, 2003 and Win 7, Win 2008 require different bios files which adds to the problem, and suddenly 500 copies of the bios can be traded for 1 copy on shared storage.
