"Unable to find device node for ./dev/ad4s1b in /dev"

[Henry Olyer]

This morning I downloaded and burned the latest CD for 8.1.

Then I took a brand new laptop, an ACER, model ASPIRE-7741Z-5731, and tried
to install FreeBSD.  (It had a copy of windoz on it.  goodbye and good
riddance.)

My point is simple, this is about as vanilla as it gets.

And I get the error, shown in the subject line.

Not sure if this is important, but the ad4s1b partition is the SWAP
partition.
