Yes, my CSPPC is also identified as "PowerUp". I don't know why Adam
Ciarcinski, who wrote the initial amigappc port code, decided that only 'E'
serial numbers are CSPPC, but I also didn't care much.

Maybe because the kernel and/or the loader are loaded into Z3-RAM? I'm not
even sure if PPC code works reliably in any other than the CSPPC onboard
RAM.

What experience did you have with WarpOS or PowerUp?

When the ZorRAM memory was recognized by AmigaOS it will be in the memlist
passed by the bootloader. But currently initppc() will only recognize the
memory segment where the kernel was loaded (which is usually the onboard
RAM).

I have a Deneb in my A3000 too and there was never any problem with it.
Neither when booting amigappc nor amiga.

The card is just ignored by the kernel. Where exactly is the problem? Does
the bootloader fail?

Did it ever work for you with my last patch?

The symptoms I had were that the system freezes, as soon as the first
character is received. I tested my serial connection with tip(1) and a
proper entry in /etc/remote.

I didn't try to boot with a serial console yet.
