How to disable the boot0 menu?

[Thomas Schlesinger]

Hi.

I've installed only DFly on my notebook as the onliest OS, so I have no need 
for the boot0 menu.

I've tried to minimize the time it's appearing by doing a "boot0cfg -s 1 -t 1 
ad0"  (-t 0 didn't work). -t is the number of ticks and there should be circa 
18.2 ticks per second, according to the handbook, but with -t 1 the boot0 
menu appears longer.

I there a way to disable the appearance of the boot0 menu completely?

Thanks,
Thomas
