Hi All,



I am developing a UEFI Option Rom driver. I found that in few
motherboard (ASrock
X100 and above, motherboard with AMD processor and MSI PC) Option Rom is
not loading. In this case, inbox driver is taking control of the device.

I checked PCI trace and found Option Rom has read from Expansion Rom
address but not started (Driver entry not called).

I tried with updated BIOS also and found same behavior. Please help.



Thanks and Regards,

Vikash
