Please try:

- Let the system boot.

- When the system is fully booted, power it off, i.e. do *not* do a
shutdown(1M).

- Power-up.

- Because the system was not properly shutdown, it will start to
fsck(1M) the disk(s).

- Before, when and after fsck is running, i.e. before and after the
"/etc/bcheckrc:" (note colon) message, *repeatedly* type:

- CTRL-\, i.e. press-and-hold the "CTRL" key and press the "\" key.
If that does not work, then start over and try:

- DEL, i.e. press-and-hold the "Shift" key and press the ESC/DEL key,
If that does not work, then start over and try:

- CTRL-C, i.e. press-and-hold the "CTRL" key and press the "C" key,

- For a default system, this will hopefully abort the boot process or/
and fsck and will hopefully give you a "(in bcheckrc)# " prompt. If
so, you are in single user mode.

I hope this helps. If it does, then please report which of the 'magic'
characters (CTRL-\ or DEL or CTRL-C)) worked.
