I found this ID on a Samsung NP300E5C, those models use the "Panther Point M" mobile chipset ("HM75 Express").
Have all 7 series chipset family 6-port AHCI SATA controllers got the same ID?

Particularly: what's the difference between this one and "8086:1e02"?

In many computers' BIOSes the protocol for the SATA controllers can be chosen, old IDE (for Win XP compatibility, don't really know any other use for it) or AHCI. If you change the protocol, the ID also changes. That's what you are seeing here. I'm surprised Samsung chose the IDE mode for this laptop given it was sold with Windows 7. Maybe they had business customers wanting to use XP, or you just have to switch to AHCI in the BIOS.

Oh, they DID choose AHCI mode. I switched it deliberately in order to see which of the possible IDE IDs it would revert to.

It seems to me that there are 2 "ID groups": the "1e0" part remains constant, and you can switch between 3 (AHCI) and 1+9 (IDE), or 2 (AHCI) and 0+8 (IDE).
The remaining IDs in the range 1e00 ... 1e0f are all RAID: 4, 5, 6, 7, e at the end.

I cannot switch this laptop to RAID, because the BIOS lacks that option: doesn't make sense, because only one single HD fits physically in.
So I cannot determine for sure the RAID IDs of the HM75 chipset.
If I look at the "210", I think RAID mode is also divided in 2 ports + 4 ports, and the following "end number groups" belong together:
0 2 4 6 8
1 3 5 7 9
I wonder now what the difference between those two series is.
"1e0e" doesn't fit anywhere systematically, perhaps the "210" chipset has 3 times 2 ports = 6 in total in RAID mode?

About AHCI versus IDE usage:

Linux uses the "ahci" driver in AHCI mode, and "ata_piix" in IDE mode, as ist seems.

The machine I'm typing this on does not boot Linux at all when switched to AHCI, so I use IDE mode instead, there must be a bug somewhere, because AHCI would hang forever at some point.

Thank you for investigating, but that sort of confirms that the IDs we user are right?
Other 7 series chipsets use the same IDs as your HM75.
