just in case I was unclear in what fields/properties I was referring to...
when you boot a new PC into WinPE or DOS and it connects to the Deployment Server and waits for the next instruction (or the Initial Deployment job), some types of computers (HP I know for sure) will populate part of the Hardware section of the 'Computer Properties'. This would usually give you the Manufacturer, Model and or Product Name at the very least. Unfortunately, with Dell computers, this doesn't seem to be the case - which means instead of a single conditioned job, i'd have to create a job for every model under the initial deployment. This defeats the purpose of being easy to maintain really.
Again, i'm not sure if there is actually a solution, or a plug in, etc or if this is just the way Dell does things.
Any help is greatly appreciated!
