I think you're irritated about the wrong thing. The RTC-memory cannot (in any standardized way) indicate more than ~65MB of system memory. This means that bypassing the BIOS and groping around in the RTC-memory is a dead-end solution. There are standardized BIOS calls to obtain the correct amount of memory, even when it exceeds 65 MB. I think the boot loader should make these BIOS calls and pass the correct information to the kernel. Tony - my personal opinion only
