X7SBL-LN2 or X7SBL-LN1 appears to halt during boot if using Super Talent STU2GMAP 2GB Pico Mini-A Pink 120X (UPC 878094010300) usb drive. When the system starts up with usb drive plugged in the motherboard, the system halts and never goes past the SuperMicro logo image. The drives are accessible and usable via the OS of any system so long as the system is already booted.
BIOS cannot get correct CHS information from the USB KEY, the Sectors per Head value return to BIOS is "0" and will cause a divide zero error when calculate the Cylinders value.
There is nothing we can do if user wishes to use this usb as boot device. The BIOS will skip the hddGetUFDCHS which the key may become an unknown/unsupported device for BIOS in order it won't cause halt at boot up.
