acpi shutdown + cool logo + nvram

[Alessio Sangalli]

Is it possible to shutdown the pc with an actual powerdown with 
linuxbios on a pcchips810? I've flashed linuxbios from cwlinux.com (I 
boot from an IDE hard disk) and I've enabled acpi on the kernel. However 
the command 'halt' didn't shutdown the machine. I had to keep pressed 
the power switch few seconds for it to turn off.

Is it allowed to insert a custom logo, instead of the tux one which is 
displayed on the first seconds of the boot? Which file is the definition 
of the logo, and is it the same format of the kernel?

Is it possible to set the nvram values to have the pc being powered up 
at a specific time using nvram-wakeup or similar programs?

Sorry for the massive amount of questions but linuxbios is *very* cool!
