I am using the SYBA SD-SATA-4P PCI SATA Controller Card with a (SiI3114) chipset flashed to IDE mode.
I have a few questions for you
Does the computer boot as far as showing the cards BIOS and the drive hooked to it or does it hard lock at the computers BIOS?
Have you tried another port on the card?
Tried another cable?
Do you have another SATA drive to try?
