sata controller rom
hi-
can someone please check this out and see if i have got this
right. i just got the wrong drive sent to me so now i have
to get a sata controller. i never bought one.
my chipset works with sata-150. but i think i can use sata-300 with an
updated sata controller rom. i'd like to buy one.
so when i search for sata controller all of these pci cards
pop up on the net. on the card they have ports for the data
cables for sata.
so i think i have to get a sata controller that will work with sata
3.0 so i can use my sata-300 drive. i then plug the sata 300
drive cables into this controller right? then i can stop trying
to find these non-existent 150 drives. i tried to order a 150
drive and they sent me a 300.
so then i guess that just like the graphics card instead of using
the sis chipset integrated functionality on the board everything is through the add-on card.
i check that controller card for linux compatibility
too like i did when i bought a nvidia graphics card.
thanks for any assistance,
jim
here is the article that talks about my chipset not working nice
with 3.0.
"Backward compatibility between SATA 1.5 Gbit/s controllers and SATA 3.0 Gbit/s devices was important, so SATA/300's autonegotiation sequence is designed to fallback to SATA/150 speed (1.5 Gbit/s rate) when in communication with such devices. In practice, some older SATA controllers do not properly implement SATA speed negotiation. Affected systems require user-intervention to manually set the SATA 3.0 Gbit/s peripherals to 1.5 Gbit/s mode, generally through the use of a jumper.[2] Known faulty chipsets include the VIA VT8237 and VT8237R south bridges, and the VIA VT6420 and VT6421L standalone SATA controllers.[3] SiS's 760 and 964 chipsets also initially exhibited this problem, though it can be rectified with an updated SATA controller ROM."
