The IDE harddisk is running for the last couple of months, and I had no
errors whatsoever (using the onboard IDE chipset of the C3k).

However it appears that writing and reading from/to the harddisk slows
down the access time quite a bit (ie. streaming a 180kbit/s movie and
writing a file with 1000kbit/s makes the movie to appear/play jerky);
whereas multiple reads doesn't affect it (ie. streaming serveral movies at
a time with 180kbit/s each).

Can anybody tell me what config options I need to boot a 2.6 kernel
without serial console support (since it's broken) and without
STI (since I don't have a graphics card in my C3k)?
I've seen a config option 'DUMMY_CONSOLE' in .config, but I don't find
how to select it in 'make menuconfig' or any description in Documentation/.

I have several machines that run headless - I use serial console then.
But I never had a situation where I didn't even have serial console ...


Thanks for any hints,
