Mui_page_directory

You can have your installer gather all of the required installation details for Firebird and pass them on to their installer.

ExecWait '$PLUGINSDIR\FirebirdSetup.exe /DIR="$test_val" \

  /SP /VERYSILENT /NORESTART'

This way, you can show the directory page before the instfiles page and know exactly what the Firebird installer did.
