Hello from Gregg C Levine Steve? How so? How did you physically connect the CF card to your IDE bus? I know a number of adapters exist to enable that feature, and I know that the 2.4 series contains the MTD (Memory Technology Drivers) functions directly, but after that, I'm lost.

So DoC _IS_ faster than IDE? If this is the case, why should it be that mounting it with /dev/hda1 as root would make for a faster boot? By my logic, I would think that having /boot and /root on a DoC would make it faster.
DoC _IS_NOT_ faster than IDE. IDE HD has the problem it need to spin up before taking any command while DoC does not. This spin up time delays you booting speed. On the other hand, once spun up IDE HD is much faster than DoC.

I've been loading the Linux kernel from CompactFlash (CF) (raw image) in /dev/hdc1, and then mount the root disk in /dev/hda1, and this is pretty fast. I shortened the delays in the IDE routine since the CF doesn't need spin up time. We really need an "intelligent" routine to find when an IDE device is ready rather than a pure time delay.
