Hello,
> What are commands 0x10 and 0x14 of the IDE controller?
0x10 was Recalibrate
0x14 no idea.
But at least since ATA 4 I think both are obsolete.
Greetings,
Thomas

Not an authoritative source, but probably right. So this would imply
that both commands are "recalibrate." The lower nibble is D/C.
http://www.pjrc.com/tech/8051/ide/wesley.html#idecommands
1XH recalibrate the disk. NB: 1XH means that the lower
nibble of the command byte is a don't care. All
commands 10H..1FH will result in a recalibrate
disk command being executed. This command has no
parameters. You simply write the command code to
the command register and wait for ready status to
become active again.
