[Oberon] AosCD.ISO.zip blank screen

[Paul Reed]

I downloaded the latest AosCD.ISO.zip yesterday and also
got a blank screen when trying to boot from it.

Holding the shift key down when booting and setting 
TraceMode=4, then c to continue, with the help of a 
LapLink cable and a 19200 baud terminal program I get:

Aos 03.01.2003

{P0 AosKeyboard.Obx not found}
{P0 MM.Obx not found}
{P0 AosRTL8139.Obx not found}
{P0 Autostart.Obx not found}

This is with an IDE drive with no Aos partitions at all.
An IDE drive with Native installed in one partition and
an additional freshly-formatted but blank Aos partition
gives:

Question: what is the meaning of the syntax at the end of

BootVol2=CD AosFS #0,R

and can I give it more info to try to find the CD drive
(slave on secondary IDE which is fairly normal)?
