Does anyone have instructions for installing 2.2.8 or 3.1 on an IBM
ThinkPad 600? FreeBSD seems to have problems with the unique memory
structure of this machine and so freezes during or shortly after boot.
Usually there are three - four beeps before the freeze.
My machine has 128MB of memory.
When I couldn't get FreeBSD installed I tried BSDI. It failed in the same
way until BSDI's tech support told me the MEMSIZ switch is needed at boot
time - you specify a value for memory size which is at least 640 kb less
than the actual memory installed in the machine. BSDI now runs without any
problems
FWIW - The comment from the BSDI tech support person was that he thought
IBM had 0 bytes of memory on the system board instead of the usual 640kb
and that a portion of the extended memory is used as the lower 640 kb by
tricks in the hardware. Hence the memory probe during boot finds extended
memory which is actually in use by the machine as the bottom 640kb.
I'd like to run FreeBSD on my TP 600 but so far no luck.
Thanks for any help,
michael
