There are sample implements under edk2\IntelFrameworkModulePkg\Csm\BiosThunk
you can refer to that use legacy int calls for providing UEFI standard protocol
interfaces.

Subject: [edk2] query regarding supporting a legacy device via uefi driver
Hi,
As legacy devices can't be served by uefi drivers. So BIOS may end up providing
2 different versions of drivers
1. On for legacy devices
2. Other for uefi supported devices
Is there any way to make uefi driver work for legacy devices? By writing some
kind of wrapper around uefi driver and mapping the exposed interface to a set
of legacy calls?
Regards,
Ritul
