[Oberon] booting from bluebottle cd results in blackscreen

[Christoph Stamm]

Hello

I've written a bootable CD for bluebottle. Booting and installing works
well on several PCs. 

Recently I've tried the same on a PC with SCSI disk and a motherboard
embedded Adaptec AIC-2940U2/W disk controller and a 3DLabs Oxygen VX1
graphics adapter. Unfortunately, booting ends with a black screen after
the message "Oberon loading".

Booting both Oberon0 and Native Oberon (beta version 31.7.00) works well
on this system.

Is it a disk controller or a graphics adapter problem or even something
else?
