I want to know whether the ATAPI/CAM support has been added to my kernel and whether DMA access for ATAPI devices has been enabled. How can I check that in my Ubuntu7.10?

Besides, if they are not yet enabled, how can I enabled them?

Thank you!

By finding-out the name of the relevant kernel config options and then grepping your config file. Example:

Code:

cat /boot/config-2.6.22-14-generic | grep CONFIG_BLK_DEV_IDESCSI

Usually, by recompiling the kernel with support for the feature you want enabled. But it depends on the feature, and whether or not it's available as a module. What brand/model hardware are you trying to get running?

I get this result,

CONFIG_BLK_DEV_IDESCSI=m

Most things in the "mega" distros (like Ubuntu) are modules, loaded as needed. Try "lsmod".

I don't know - it was just an example of how to check. I had done a quick Google and got the impression that ATAPICAM was related to IDE SCSI emulation. By not answering my question about what brand/model hardware you are referring to, you've made it harder to understand what exactly it is that you need.
