Urgent help required please.
I updated the Bios on a GA-MA790FXT-UD5P to F7.  Now the machine will not boot. It hangs on "update new data to DMI". I have tried replacing the BIOS update with previous versions (F6h, F6) - same problem.  The only "odd thing" I can describe is as follows:
On the PCI Devices Listing  (on screen) one entry in the list now seemd wierd. As the list appears on the screen - everything looks normal.
 When the "verifying DMI Pool Data ........  "   followed by  "AMD Data Change....   Update New Data To DMI!   Update Success " appears at the bottom of the screen, one of the entries in the list appears to alter in the following way:
In the SVID column the number changes from 1458  to  1 58  with a blank space where the  4  was. This device is a USB 1.1 Host Controller on  IRQ 11
I'm desperate to get this machine running again.
Any advice would be gratefully received.
Thanks
