FreeBSD fails to boot from CD on Notebook

[Martin Siebel]

Hey,

after failing to get FreeBSD working with my ASUS F70SL Notebook I tried 
to get it to work on [I][COLOR="Blue"]Toshiba Tecra A10-M14[/COLOR][/I].

I downloaded the [FILE]FreeBSD-9.1-REALEASE-disc1.iso[/FILE] from the 
official FreeBSD homepage and burnt it with [I][COLOR="Blue"]Ashampoo 
Burning Studio 2013[/COLOR][/I].

Now, if I select "Boot from CD-ROM" in my notebooks BIOS it detects the 
CD, starts to boot from, it but only for about 1 second. After this the 
screen blackens, the notebook reboots and boots normally from HDD (even 
tough I still have the CD inserted and the CD-ROM drive is still the 
first boot device).

This happens that fast I don't even have a chance to get a picture of 
the error that might occur.

Any ideas about BIOS settings I may change?

I burnt the CD twice by the way, with different burning software, to 
avoid damaged or incomplete disc.

Thanks in advance!
