File it away under 'compatibility cruft' then ;) The size difference this makes is still very significant. In case of an IP27 kernel default config: text data bss dec hex filename 2626662 747232 165760 3539654 3602c6 vmlinux 2907645 1283808 165760 4357213 427c5d vmlinux The first kernel was built with the stock Makefile; the second was modified to use 64-bit ELF using gcc 2.95.4 / binutils 2.13.2.1. So I'd call those 817559 bytes kernel obesity ;) > > > Well, as far as I know, and I'm probably right, it _does_ have some memory > > > there.

The weirdness is not in that part; what's weird is placing the rest > of memory somewhere else. Not uncommon on SGI systems. The Indy's memory also starts at 128MB; only a few kB for exeption vectors are mirrored to physical address 0. Ralf
