The TP600s require some special hacks to get going. I have a 600E that I
put 6.1 on a couple of weeks ago and needed to do the following:
1. Update to the latest BIOS and embedded controller firmware.
2. Boot into DOS with the PS2.EXE tool and disable all of the devices you
aren't using. Make sure at least 3 IRQs are assigned to PCI (I have 9, 10,
and 11 assigned).
3. Add 'hw.cbb.memory=0xd8000' to /boot/loader.conf.
Boot with that and it should work even with ACPI.
If you search around you might find a suggestion to add a bunch of
hw.pci.link type loader.conf tunables. I haven't found this to be
necessary if there are sufficient resources available.
The only casualty appears to be sound, but I can live without that.
