Hi Gavin,
it dies EXACTLY before any of the boot info comes up. Step by step:

  - bootloader : ok
  - boot menu : ok
  - select any option (except 6, but any cmd from there that will take 
me attempt to boot will simply panic).
  - line in same gray coloured text comes up, (from memory, kernel 
0x..., segment 0x.... etc). as soon as that finishes...
  - font changes to bright white. not 1 line of detection comes up, and 
the panic happens.


I have not been able to boot any freebsd combo. tried disabling anything 
that I could, no luck. not even the installer. disabled acpi, DMA, safe 
mode, single user. zilch

I hope that is something to go by.

I'll take the box apart tomorrow to see what precise motherboard it is. 
Plan B is gentoo :(

thanks for any pointers you / others can give :)

Cheers,
Beto
