USB 在 OpenBSD 5.6 安裝程序中不起作用

我正在嘗試在我的 2012 Mac mini（四核 Intel i7）上安裝 OpenBSD 5.6 amd64，但 USB 在引導過程中停止工作，我的發光鍵盤變暗就證明了這一點。如果沒有可用的鍵盤，我將無法繼續安裝程序。

鍵盤在 Mac mini 上的 OpenBSD 5.5 amd64 下安裝和使用期間工作正常。嘗試在另一台 Mac mini（雙核 i5）上啟動 5.6 安裝程序也會導致同樣的問題，因此這台特定的機器不會出現問題。

我從 5.6 的發行版開始嘗試 install56.iso、install56.fs、cd56.iso 和 bsd.rd。我還從最近的兩個快照中嘗試了 install56.iso。這些都不起作用。

這是啟動時螢幕上的文本輸出、錄像和手寫（可能有錯別字）：

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

在啟動時提到了 USB 和鍵盤，但此時我的背光鍵盤不亮，按鍵沒有任何作用。我沒有其他鍵盤可以使用。我嘗試將鍵盤插入系統上的所有 USB 埠，但沒有幫助。

任何想法可能是什麼問題？有沒有什麼方法可以在不需要 USB 鍵盤的情況下控制這個系統？

我不知道問題是什麼，但它似乎已在目前分支中修復。您可以下載快照（例如從http://ftp3.usa.openbsd.org/pub/OpenBSD/snapshots/amd64/或其他鏡像），它現在應該可以工作了。

我在捷波準系統（JBC375F3AW-2930-B，但這可能適用於大多數或所有型號）上安裝 OpenBSD 5.7 時遇到了同樣的問題。修復方法是進入 BIOS 設置程序，然後在“高級”螢幕上，將“作業系統選擇”項設置為“Android”。
