loader crash - 5.2.1

Hi,

I'm trying to get 5.2.1 up and running on an old Toshiba 740CDT (pentium
166).  I've installed from source built on another machine.  When I move the
drive back to the Toshiba and try bootup, loader crashes before presenting
the loader menu (safe mode, disable acpi, etc.).  The moment it crashes the
machine also reboots.

I took a shot of the crash output and have reproduced it here:

BTX loader 1.00  BTX version is 1.01

       0b 00 20 00 69 95 00 00-00 00 00 00 1e 00 30 a0

I've tried disabling ACPI by putting hint.acpi.0.disabled=1 into
/boot/device.hints.

Being a notebook the BIOS is pretty sparse when it comes to settings.  Not
sure what to do from here.  Can anyone help me please?


Thanks,
