Nope. Up to 64 MB would fit into the regular CMOS, but Compaq decided to announce only 16 MB there. As for the ``options MAXMEM'', it's not that the kernel would become too large, but that it will _always_ use exactly this amount of memory if MAXMEM is set, while it uses the CMOS value otherwise. Since (obviously :) not all PCs are equipped with 96 MB, we rather ship the kernel that only recognizes up to 64 MB as a default. Should be enough to compile your own one, which is recommended procedure anyway. -- 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. ;-)
