[asterisk-users] Flash IDE

Disable DMA on that drive. Thee HD/DOM/CF-card does not support DMA and
linux tries to "DMA" it.

In the last 2 years I have personally killed 2 DOMs of 512 MB. They where
running Debian Sarge, and were set up to run on TMPFS. The reason why they
died is because I tested the installation on those systems: this means zero
out HDA and then copy it all over again from a backup.

In real life, in real usage, I think those will last quite more, since the
disk is not been written all that much. But still, be warned.
