FreeBSD 6.2 hangs on Sun Ultra 80

[Gilles Celli]

Hi,

I tried to install FreeBSD 6.2 via CD-ROM on a SUN Ultra 80 (2x  
Ultrasparc-II at 450MHz / OpenBoot 3.23 / 1.2GB RAM) with Raptor GFX  
graphics-card,
monitor and keyboard.

After booting from the CD, it hangs with the following message:
* Nothing to autoload yet
* Jumping to kernel entry at 0xc0060000

and then hangs :-(

Could it be due to the graphics-card ? Any work-around?

I've also read that you can boot in serial console mode...
But how do I do that ?

Any suggestions greatly appreciated,

Gilles Celli
