<h3 id="status"><strong>Current status</strong></h3>

<p>
The current target platform is the HiFive Unmatched board.

<p>
When booting the HiFive Unmatched board, write an install/miniroot image
to a USB flash drive, and boot with that drive plugged in. Make sure you
also have the microSD card plugged in that shipped with the HiFive Unmatched
board. The board should auto-boot the OpenBSD bootloader, which will load
the bsd.rd RAMDISK install kernel.
