Alas, there are other system ``niceties'' that also subtract some amount from the BIOS basemem, like hard disk parameter tables for the custom-selectable hard disk type. (BIOS vendors should really use the BIOS stack for this, but only AMI seems to offer this as an option.) I'm not sure whether we are very interested in preserving this information. Anyway, i don't think the wasted at most one page would hurt very much. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
