I am leery of any SATA controller that I've never heard of, and I feared that perhaps this was something I already knew from work and didn't like. Some googling suggests it's actually a JMicron controller that is decent and fairly well supported by 6.2-STABLE. Can anyone confirm that?
Yes, JMicron controllers are a pretty standard feature of most modern Intel-based boards. Mine works without any problems: ... atapci0: <JMicron JMB363 SATA300 controller> port 0xbc00-0xbc07,0xb880-0xb883,0xb800-0xb807,0xb480-0xb483,0xb400-0xb40f mem 0xff6fe000-0xff6fffff irq 16 at device 0.0 on pci3 atapci0: [ITHREAD] atapci0: AHCI Version 01.00 controller with 2 ports detected ata2: <ATA channel 0> on atapci0 ata2: [ITHREAD] ata3: <ATA channel 1> on atapci0 ata3: [ITHREAD] ata4: <ATA channel 2> on atapci0 ata4: [ITHREAD] ... ad6: 157066MB <Hitachi HDS721616PLA380 P22OAB3A> at ata3-master SATA300 acd0: DVDR <ASUS DRW-1814BL/1.10> at ata4-master UDMA66 ...
I do find it odd that they would use discrete chips for the NIC and extra SATA ports, when the chipset contains both.
Mainboard manufacturers usually like to offer Parallel ATA, which is not available in newest Intel chipsets, hence there is a need for an external chip. I guess, Serial ATA comes as a bonus with such external chips, and also provides the user with more choice on which controller to use. Also, I don't think ICH8 southbridge has integrated Ethernet networking capabilities -- these are usually added as an external chip, connected by PCI Express, as the following diagram illustrates: <URL:http://www.intel.com/products/chipsets/g965/prod_brief.pdf>.
