I'm having trouble booting into Knoppix from my cdrom drive.

I set my cdrom as the first bootable device. I restart with the cd in the drive. I get to the main Knoppix screen (with the logo and message telling me to hit enter to boot, etc..). I hit enter.
The next screen I see has the linux penguin in the top left hand corner. (i've seen this screen before. This is where it detects my hardware, etc..).

Except, the screen stays completely blank (except for the penguin). Nothing happens. My cdrom stops spinning. Its just stick there with a little blinking cursor.

I have 2 cdrom drives. In the bios, i have tried to boot first from each one (still no luck).

I have even disabled my harddrives so that the *only* thing that boots is my cdrom drive.
Same thing. Keeps getting stuck at the penguin.

My hardware configuration:
Asus A7V8X-X motherboard
Athlon XP 2600+
1GB Crucial RAM
ATI 9200 Vid Card
Promise HDD Controller (i'm not using RAID. I'm just utilizing the "extra" 2 IDE ports).

The way my drives are setup:


*Main HDD IDE Port on Motherboard*
HDD 1 (system)
HDD 2 (data)


*Main CD IDE Port on Motherboard*
CDR/DVD
DVDR

*Promise HDD Contronller - Card is in a PCI Slot*
HDD 3 (data)
HDD 4 (data)


When my computer boots, it recognizes my 4 drives in this order:

Primary Master - HDD 1 (system)
Primary Slave - HDD 2 (data)
Secondary Master - CDR/DVD
Secondary Slave - DVDR

It then goes to my HDD Controller and detects my 2 additional drives.

At this point, it either boots to windows, or to the Knoppix CD (which is what it is currently set to do).

Knoppix logo screen...
penguin....
thats it. Stuck at the penguin.


I am using the latest version of Knoppix "KNOPPIX_V3.4-2004-05-17-EN.iso" (i have verified the MD5 hash and it checks out).

I've also used the previous release: "KNOPPIX_V3.4-2004-05-10-EN.iso". Still doesn't boot.

Has anyone come across this?
Thanks.
