I am working with some proprietary pieces of hardware in NT 4.0 Workstation, and I need part of the B0000 range in order for my hardware to operate properly. When I configure the card to the B0000 range, the event log tells me I am having a memory address conflict with VGASAVE. According to the NT Diags, VGASAVE resides at A0000-BFFFF and I cannot figure out how to change that address to something available. In my current configuration, I have disabled VGASAVE completely, and my hardware/software applications work properly. The only concern is if this will cause an unseen problem, or if it's just a matter of time before it crashes something in NT. This configuration will be used on a large scale and will be under heavy scrutiny, so I need to make sure that I know my stuff before it's released. I've searched many many resources and have found nothing that explains its purpose. So again, I ask what does VGASAVE do, and is it safe to disable it?
