Bluebottle doesn't support AMD X2 multiprocessor. It works, however, in single processor emulation.

You can limit the number of processors used by setting the config string "MaxProcs". Setting it to a negative number will emulate single processing on a multiprocessor machine.
No, you don't need a custom iso for that.
1) Boot from CD with Scrolllock enabled (to get in the Boot loader menu)
2) Type "MaxProcs=-1" (without quotes) and then press return
3) Type "c" and then press return to continue booting

Betreff: [Oberon] Booting Crazy-Fresh: Black screen on ATHLON64 X2
since two months I have a new computer with Athlon64 X2 dual core
processor, Asus A8N-SLI Premium motherboard, 2GByte RAM,
nvidia 7800GTX graphic card, one PATA and two SATA harddisks.
Installation of Linux and Windows in multiboot-configuration took some time,
so I have waited till now to try booting Bluebottle iso-image.
(Installation of XP SP2 on the first SATA harddisk was only possible
after disconnecting the PATA device, and nvidia graphic card driver
shipped with Debian GNU/Linux was very instable. Currently I am using
Gentoo Linux with the latest closed source nvidia drivers. It works fine, but
when switching from text- to graphic-mode at boot in one of twenty cases
I get a black screen and have to press reset botton.)
But back to Bluebottle:
I tried to boot the latest Crazy-Fresh iso image, and another older BB image.
In each case CD-ROM beginns to load, but comes to rest after a few seconds.
And there is no output on TFT-screen. All black.
I just downloaded last Native-Oberon (05.01.2003), wrote the image to floppy
and booted it. It is booting fine, displaying the good old Oberon start screen!

How can I limit number of processors? Have I to build a custom iso-file
on my old computer?
