Hi Jeff,
For several times I tried libata on small machines equipped with either
CompactFlash or IDE DOM (Disk-On-Module). All those machines with small
flashes (<= 256 MB) were about 35-40% slower under libata than under the
plain old IDE driver. I realized that all the slower ones were running

Thus, I have implemented the 32-bit mode to bring the performance back
to the level of the old IDE driver. I jumped from 1.5 MB/s to 2.5 MB/s,
which is an important difference at this level of performance, especially
when large files are read. The 32-bit mode is enabled using the ioctl
which
