Dell Insprion 620/Vostro 260 NO Bios Setting for AHCI
Interestingly I could not even update the bios without the INTEL Management Drivers.
Checking in the Device manager the machine is using the ATA drivers not the AHCI drivers
AND the INTEL RST drivers will not install.
Why is that?
I did try updating to Bios version A04 but this made no difference.
Solved! Go to Solution.
The manual shows AHCI enabled by default. "SATA Mode — AHCI; RAID (AHCI by default)"
Ok I found it listed Under system configuration in the manual. This option DOES NOT EXIST in an actual Inspiron 620 F2 CMOS MENU.
The bios is FORCED TO ATAPI By Default AND Has no RAID OR AHCI modes under ADVANCED, SYSTEM CONFIGURATION.
The Drivers in device manager are the ATAPI aka non AHCI drivers.
My SSD Firmware LIVE Linux Update CD also says the drives are in ATA not AHCI mode. (This means its BIOS not Registry or Driver)
Microsoft AHCI.SYS is not loading or installing nor is the INTEL RST driver.
Intel® Rapid Storage Technology supports the following Intel® chipsets. But Refuses to Auto or Manual Install on a 620.
I also ran into this issue. Dell please fix this in the BIOS! One, the documentation says the default is AHCI, but in reality the default is ATA. Second, this setting is not configurable by the user. C'mon this is basic stuff here....
I also ran into this issue. Dell please fix this in the BIOS! Bios Upgrade is needed ! AHCI is very important for Windows7 OS . Speed improvement on HDD when SATA AHCI is enabled !!!
I recently purchased a 620MT and having the same problem - not able to turn AHCI on and not getting the performance expected. I have an SSD I want to use but don't get anywhere near the performance AHCI would give. - I have tried it.
Has anyone got a workaround for this? Is there a better motherboard that would fit straight in, or would I be able to add a PCI-E card, attach the SSD to that card and boot from there? I'd even be happy to buy a decent motherboard if it'll fit in the case.
Dell need to address this for us, using a motherboard without AHCI these days is crazy. I wouldn't have bought the machine if I knew about this issue.
Very dissapointed in DELL.
There is a PCI-E card that you can boot from. Apricorn Velocity Solo Storage controller.
Mfr Part #:VEL-SOLO
The Velocity Solo is an industry standard PCIe 2.0 card designed to add a 2.5" Solid State Drive (SSD) via a SATA III connection.
NOTE: Solid State Drive sold separately.
I did some research and found out that the chipset in this system, the H61, simply doesn't support AHCI or RAID. There's no way to enable either for a reason.
Wish I had known this. The value of this system just really went down the tube if you intend to throw an SSD in there.
