This was the filename for the firmware that we used, you can probably search for it elsewhere (filename is also pretty descriptive): 9207_8i_Package_P16_IR_IT_Firmware_BIOS_for_MSDOS_Windows.zip
The OS names confused me at first until I realized they referred to the OS you run the flash utility from. I got my HBA flashed now I just need to get my cables and I should be good to roll. Thanks so much for your help.
