Setting MAXMEM to 768M isn't going to do you any good. Actually, it depends on which system you're referring to. This one actually has 576Megs of ram but the IBM ThinkPad BIOS will only show 512Megs. The system sees all memory without the MAXMEM option, I just remember it was needed in older FreeBSD versions from atleast 6 years ago since I remember without the option, it will only see 64megs or something.
