Hello everyone,

As I've wrote in url[1], I recently got a Gigabyte Mp30-AR0 (rev 1.1)

motherboard from a online second-hand market.

Thanks to those helpful Linux enthusiasms, I'm now clear that I should firstly

find a way to turn the motherboard from U-Boot mode to UEFI mode. And I

saw a discuss thread from this mailing-list(url[2]), especially messages,

as url[3] to [6].

I do not want to write UEFI firmware into onboard flash or EEPROM. 

Instead, I wish I could put the firmware just in a USB-storage or SD card, 

so that the original on-board U-Boot and build-in OpenLinux. 

So I would like to boot as Gordan Bobic and Michael Howard had discussed:

(Also referring to url[4], [5] and [6].)

1) u-boot (on-board)

2) UEFI (wherever u-boot can fetch it from)

3) grub (off the UEFI FAT partition on the target disk)

4) Kernel (/boot partition)

However, I couldn't find out how to set U-Boot to boot as above.

One another problem is that, I couldn't get access to url[9],

which is mentioned in url[3], [7] and [8].

Thank you for your generous help in advance.

Also please pardon my not reply on time because I couldn't apply your advises

into use immediately.

BTW: Please tell me if there is any need tool like RS232-to-USB converter etc.
