If this is meant for "Eduard Bloch", I will concur.

In contrary to you, I know what I am talking about and try to
write README.ATAPI as unbiased as possible. If you like a real discussion,
you should stop sending your totally biased remarks.

So why don't the Linux kernel developer enable DMA?

Oh my god, how is it possible that a person who is so clueless and biased
is still tolerated in debian.org?
But thank you! It turns out that people who are completely clueless
sometimes have the ability to point to problems in comprehension.
I added this paragraph to README.ATAPI:
/*--------------------------------------------------------------------------*/
First a note: there is no SCSI emulation on Linux, but there has been
some kind of SCSI integration. To explain the difference between SCSI emulation
and SCSI integration let us look at an Operating system that implements both,
Windows NT:
Win NT implements SCSI integration, if you open "\\\\.\\SCSI%d:", BusNo,
you will be able to send generic SCSI commands to any SCSI speaking drive
on that bus. ATAPI drives just show up on a specific Busnumber, SCSI drives
that use a 50 or 68 pin connector show up on different Bus numbers.
Note that Microsoft obviously did copy my ideas I did implement in August 1986
for SunOS-3.0 :-)
Win NT implements SCSI emulation by not only showing drives that natively
talk SCSI on the ATA/IDE cable, if you send generic SCSI commands via ioctl's
to "\\\\.\\SCSI%d:", BusNo. Win NT also shows you plain ATA drives that do not
understand SCSI commands in firmware. Win NT allows you to send SCSI
commands to the kernel and the kernel translates the SCSI commands to ATA
commands with the same meaning, so Win NT emulates SCSI for ATA drives.
Linux does not emulate SCSI command transport for vanilla ATA drives, so there
is definitely no SCSI emulation in Linux.
