Just a stupid question: Why does the boot loader should know if there's more than 64M or not on the system ? Why couldn't it simply detect 64M at most, and let the kernel find the rest by itself ? Anyway, is what's done with the MAXMEM option, isn't it ? Moreover: Is there any STRONG reason to ask the BIOS for the memory amount ? Couldn't it search for the memory ?
