(I think its the memory.) Yes, when you get the boot: prompt, type "-c" to get to the configurator. At the config> prompt, type iosize npx0 32768 or whatever size you want, expressed in KB. Then "quit" the configurator to continue the boot. This change won't take effect until the NEXT reboot, not this one. Also, try the following config commands while you're in there; "help" and "ls". This might not help you if you can't even boot the floppy GENERIC kernel. You may need someone to build you a custom kernel to put on your boot floppy. Or just physically remove some memory...
