Beginner, here --To obtain 3.0 capability I added a USB PCIe expansion card (Renasas controller) to an older computer (MSI G41M-P25).

Everything works as it should except I can't boot from the 3.0 USB flash device attached to the card, because this computer's BIOS doesn't recognize the device as "bootable" -- either because it doesn't recognize any device on a PCI bus as "bootable" or because it doesn't recognize any USB 3.0 device as "bootable."

ASSUME the card does not include "expansion ROM" or "ROM emulation." (Likely, it was only $13)

Is there some way I can boot from a device plugged into this card?

Note: If asking for info please give me the command to get the info. As I said, I'm a beginner.
