When I was running 2.2, I did have the drive working with the "ide2=0x9400, 0x9002 ide3=0x8800, 0x8402" parameters to help linux find the Promise controller (from http://www.geocities.com/ender7007/), but I upgraded to 2.4 I had to disable the Promise driver.
It looks like if I compile the Promise module (pdc202xx.o) , my Debian system hangs at startup, exactly as Knoppix does. If I do not include pdc202xx.o, my system boots & works fine.
drivers/ide/pdc202xx.c includes the following notes: * Promise Ultra66 cards with BIOS v1.11 this * compiled into the kernel if you have more than one card installed. * * Promise Ultra100 cards with BIOS v2.01 this * compiled into the kernel if you have more than one card installed.My BIOS is 2.01, and I have only a single Promise) card installed (the one built-in to the A7V motherboard).
I wonder if the driver could be hanging trying to detect a second card or something like that?
Is there any way I can disable that module from the knoppix boot? kbPS. Including my full previous message, because I sent it from a non-subscribed email address, and because I added Andre from pdc202xx.c

I'm recompiling the kernel to enable the Promise driver, and will see what happens...knoppix noapic may help, too,Nope. :-(Yes, that counter-intuitive setting was necessary for my installed Linux system. :-)or just disabling some odd BIOS options like "plug and play OS" that basically says to use a wrong interrupt (0) for all PCI devices. You should turn that option off for Linux, even that Linux IS "plug&play". ;-)Thanks kb
