Do you have separate settings in setup for loading images from OptionROM,
images from the fixed media and removable media, if so whether the OptionROM is
not set to Never Execute?. I have created OptionROM multiple times using
signed efi and efirom and never seen an issue.
Thanks

Did you check the platform PCDs for loading OptionROMs when SecureBoot is
enabled?
## Pcd for OptionRom.
# Image verification policy settings:
# ALWAYS_EXECUTE 0x00000000
# NEVER_EXECUTE 0x00000001
# ALLOW_EXECUTE_ON_SECURITY_VIOLATION 0x00000002
# DEFER_EXECUTE_ON_SECURITY_VIOLATION 0x00000003
# DENY_EXECUTE_ON_SECURITY_VIOLATION 0x00000004
# QUERY_USER_ON_SECURITY_VIOLATION 0x00000005

The EfiRom program doesn't alter the UEFI Driver, it only packages the driver
as part of the PCI Option ROM. If you used the signed driver with EfiRom then
that's what gets bundled into the OpROM image.

Yes,
When Secure boot is disabled UEFI driver successfully loaded.

The EfiRom command should not strip the signature from the signed driver. Can
you confirm that the PCI Option ROM loads the UEFI Driver when UEFI secure Boot
is disabled?

Hi Brian,
Is there any specific flag for EfiRom that should keep the signature of the EFI
file?
I run the following command:
# EfiRom.exe -f 0x15b3 -i 0x1003 -e 0a.01.10_uefi.efi -o 0a.01.10_uefi.rom
Then I see that the ROM image fails to be loaded during POST when UEFI Secure
boot mode is enabled while the original signed efi image can be successfully
loaded from the UEFI Shell.
Thanks,
Vladimir
