Also spelled "ATA is underengineered".

(AKA MS-DOS 7.0 with a Windows 4.0 shell).  Which in turn is the same as
the MBR bootloader of many preceding MS-DOS versions.  Yes.  This does
seem to be the case.

And here's an open-source functional equivalent, by the way:
http://sourceforge.net/projects/ms-sys/
It's installable into the MBR 446-byte boot area in sector zero from Linux.
