Universal Drivers for all models, when possible
I suggest that Dell have drivers that work for all models but use the same drivers for the operating system.
Ethernet/Wireless adapter, have a Windows # 32-bit driver and a Window # 64-bit driver. Have the drivers for this adapter work for all models.
Dell QuickSet, have a Windows # 32-bit driver and a Window # 64-bit driver. Have the drivers work for all models.
Yes, chipset, audio, video drivers will be different, depends on the model but having the same drivers for each item(adapter, Dell QuickSet, etc...), it makes it more universal, easier for downloading the drivers for each item.
