Hi all and sorry for my poor english.
I could find no 3D, which speaks of my motherboard and the new UEFI BIOS U1A, so I decided to open this 3D to tell and share my thoughts.
At first glance it looks great and has solved several problems that i found in the old BIOS series:
1 - fixed a problem enabling the UrP, which prevented the computer to power on after a shutdown.
2 - fixed allocation problems of the BIOS PCI cards: I use both PCI slots provided by this motherboard, one for a SCSI controller and one for a SATA RAID, but previously they were not working properly and I could not boot from ODD connected to them.
3 - solved a problem of recognition of my gamepad (VID_04FC&PID_5001&REV_0100) when the computer is reactivated from hibernation, which forced me to reinstall every time the device.
4 - The POST is almost instantaneous and aesthetically everything is much more "cool". :-)
I found only a couple of minor issues:
1 - access to the UEFI BIOS with the DEL key usually stops it if I turn on the computer with my gamepad (VID_04FC&PID_5001&REV_0100) plugged into a USB port: I think it is due to the fact that the UEFI BIOS is unable to properly detect the device, but if I do not try to access the BIOS, the Windows 7 starts without any problems.
2 - The UEFI BIOS recognizes sometimes twice the same device, and makes it appear twice in the list of boot devices.
3 - UEFI BIOS sometimes uses a general entry to catalog a boot device, and it is not clear to which unit it refers.
4 - for these reasons my computer, which has many devices, exceeds the limit of 12 units of boot and when I press the F12 key to perform a selective boot, the UEFI BIOS does not show all of the devices from which to boot and it shows only the first 12, without offering the possibility of a scroll on those that are not visible on the screen.
