When you get the boot prompt, enter -c to enter the configuration screen... at the config> prompt, enter ? to get help enter ls to list devices. there is a device called npx0, and if you set it's iosize to 32768, the kernel will only see 32MB NEXT time you boot (NOT this time). so set it like this... iosize npx0 32768 (or whatever) then use ls again to see the change use q to quit the system will finish this boot sequence and probably panic like before. Don't worry, be happy. Next boot should recognize your change (check the "avail memory" during boot process) For more reading, search for MAXMEM in /sys/i386/conf/LINT Unix systems measure "uptime" in years, Winblows measures it in minutes.
