I don't even think the first 1mb is used by the kernel >because it's divided. The first 640K is used by the kernel. The next 384K is the ISA hole and the remainder is "extended memory". The message indicates that the BIOS wants to reserve 1K of memory at the end of 'base' memory. The message is harmless. In previous releases, FreeBSD went ahead and used the memory, but now we do what the BIOS wants and just warn about it. The warning should be removed or only come out if the amount of memory the BIOS wishes to reserve is unusually large. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
