sparc64 boot0

[volker at vwsoft.com]

Dear list,

I'm about to prepare boot media for a sparc64 installation (bought a 
cheap used Blade 1500).

For amd64/i386 I usually do a bsdlabel -wB ...; newfs ; make 
install{world|kernel} blablabla to get things on a bootable usb thumb drive.

I've already finished the cross build for TARGET_ARCH=sparc64 and am 
wondering which boot0 I will want to use for the thumb drive to get the 
Sun Blade booting?

Haven't tried to power the Blade up (so I have no idea if there's an OS 
already on that used machine).

Thanks

Volker
