USB가 OpenBSD 5.6 설치 프로그램에서 작동하지 않습니다

2012 Mac mini(쿼드 코어 Intel i7)에 OpenBSD 5.6 amd64를 설치하려고 하는데, 조명이 켜진 키보드가 어두워지면서 USB가 부팅 시퀀스 중간에 작동을 멈춥니다. 작동하는 키보드가 없으면 설치 프로그램을 진행할 수 없습니다.

이 Mac mini의 OpenBSD 5.5 amd64에 설치하여 사용하면 키보드가 제대로 작동합니다. 다른 Mac mini(듀얼 코어 i5)에서 5.6 설치 프로그램을 실행하려고 해도 동일한 문제가 발생하므로 이 특정 컴퓨터에서는 이상한 일이 아닙니다.

5.6 배포판에서 install56.iso, install56.fs, cd56.iso 및 bsd.rd를 사용해 보았습니다. 또한 마지막 두 스냅샷에서 install56.iso를 시도했습니다. 이들 중 어느 것도 작동하지 않습니다.

시작 시 화면에 표시되는 텍스트 출력, 비디오 및 필기 내용은 다음과 같습니다(철자 오류가 있을 수 있음).

Welcome to the OpenBSD/amd64 5.6 installation program.
(I)nstall, (U)pgrade, (A)utoinstall or (S)hell? _

시작 시 USB 및 키보드가 언급되지만 이 시점에서는 백라이트 키보드가 켜지지 않고 키에 아무 일도 일어나지 않습니다. 사용할 다른 키보드가 없습니다. 시스템의 모든 USB 포트에 키보드를 연결해 보았지만 도움이 되지 않습니다.

어떤 아이디어가 문제가 될 수 있습니까? USB 키보드 없이 이 시스템을 제어할 수 있는 방법이 있습니까?
