New SATA Controller Card, Windows wont boot, how to load drivers?

If you do not get specialized help for flashing your BIOS, and have strong reason to believe this will resolve your problem which I haven´t seen advised here yet, then realize you are proceeding at your own risk in a risky operation.

If no one here knows what you need then I would contact the mobo or PC tech support. You should have already googled and read everything about it. You can ask for specific help to receive more response in your own thread which is titled to exactly explain what you need.

I know this is an old topic but I wanted to answer it for anyone the run into this issue in the future and may come across this in a web search.


The Motherboard Bios and Bios on the SATA card are conflicting. I had this same problem with a card I had that was Sil 3114 based and had all but given up on using that card until today. I needed more ports and I was determined to sort this out. I tried a fresh install of Windows and same issue. I tried updating the Bios on the Sil SATA controller and still same issue.


I was able to resolve this by erasing the BIOS flash on the Sil SATA controller. If the Bios chip is removable just remove it but if not boot to DOS and run UPDFLASH.exe if you know what type of flash memory you have select it from the list. If not and i did not i selected option 7. Read the bios version and then erased the flash. After erase I read the version to verify it was blank and exit.
Reboot PC with drives attached and install the driver from Sil. This should work for similar cards even if they are not exactly the same. I did not need any RAID functionality out of the card just additional ports for more drives and the card is now detected as an SATA storage controller and working great. You can always flash the latest Bios back if you need to.


If you have question just reply to this thread and I will try to help.

I had 2 of these cards in a new fileserver I finally got around to building with parts I bought 10 years ago. System would hang for 10+ minutes as soon as Windows started to load. I actually replaced one card that seemed to be the issue (system seemed to not like having the second card in) but still had the same problem. Erased the BIOS from both cards and bang, no more hang up. Drives had to be redetected by Windows once booted up but otherwise it was fine. Lost those drives from the motherboard BIOS boot options but that's fine with me anyway.


Lots of Googling found me nothing earlier until I stumbled on this today.


Also thanks to the people linking to the driver/utility collection!


You're all lifesavers. I would've kept throwing money at this until something worked.
