Joshua, What Michael has said is likely your problem: you are out of option ROM space: To clarify; what Michael is talking about is the RAM the BIOS requires at POST when enumerating BIOS devices (addon/integrated option ROMs). The Patch will allow this to be shifted somewhat in memory; it may help a bit. You only have about 64k of this "low" RAM to work with.
