It should, but it's a solution in search of a problem. > 4 might be good enough for the ACPI tables if you can bound it. Already doing that (rounding to 128k, warning if >64k), but it is not a definitive solution. We also do (4) for ROMs, since VGA BIOSes use only 36k out of 64k and iPXE ROMs use only ~200k out of 256k. Paolo
