FWIW my new work plan9 box (an HP WX4200) boots plan9 but doesn't see SATA using the labs iso - Erik's 9atom works fine.
The onboard Broadcom nic is junk but I put an intel card in it which "just works"™. The bundled nvidia nVidia Quadro FX 540 works with vesa - but swapped it for a Geforce2 which supports acceleration and so feels a bit snappier. now if I could just get some fast disks... -Steve
