Understood, but I actually took my 2.2.19 .config and ran "make
oldconfig", then "make xconfig" making no changes, just saved it
based on prior experience, then the usual "make dep bzImage modules
modules_install install" etc, you know that drill all too well. I
seem to recall there was one new item while oldconfig was running.
Cannot rememeber what it was. I do remember replying to make it a
module.
I am likely to do the benchmark tonight to get hard numbers on the
difference I sense. I am a QA/Testing Specialist, so I am all to
aware of the importance of keeping the variables all the same. My
initial background was with assembler back in the real core
memory/keypunch days where I disassembled and heavily modified the
OS, compiler, assembler, system utilities and wrote a new way to load
the OS, compilers, etc from scratch to a new disk. Ony advising you
so you have a sense of my mindset and level of understanding. Not
current with intimate x86 details or assembler, but will someday now
that "falt" memory is back! :))
I will let you know what I find. If in meantime you feel there are
other things needed or for me to check please let me know and I will
be most happy to assist.
