How are you going to get that message (or a filename to get it from), plus the check and such into 12 bytes? :-\ Remember we're darn low on space in the boot block. It seems to me not doing the check at all, and just loading the kernel, and hoping it works would be better. Then you could save the bytes used today to find out how much memory we have and instead do that right in the begining of the kernel code. Specially if we don't use the value anyway. (!?) /Mikael
