Refer to my last post with the screenshot. I put my floppy drive back in and copied the files from the SB750 folder onto the floppy. I updated the screenshot.
Just to be sure you said to "In the BIOS, go to Integrated Peripherals. Set OnChip SATA Controller to Enabled. Set OnChip SATA Type to AHCI. Set OnChip SATA Port4/5 Type to As SATA Type." I only ask because earlier someone had said to set "OnChip SATA Type [Native IDE]".
So where in the BIOS do we ensure that the floppy drive is active?
Ah yes, I see now. Your screenshot looks correct.
About the SATA config, what I said is correct. To enable the floppy drive, go to Standard CMOS Features and set Drive A to 1.44M/3.5".
