I'm looking for a product similar to the Dell DRAC that can give low-level access to a PC from a remote location, i.e. access the BIOS, reboot the PC, etc. These are common in servers, but I have yet to find a simple, relatively low cost PCI adapter to accomplish this with a standard PC. Manufacturer-specific cards like this can be found on eBay, but I doubt they'd work in a normal PC.
Any suggestions would be appreciated.
