Re: getting 10.1 amd64 onto a usb as mbr

[Henry <nbsd4ever%gmail.com@localhost>]

YES!  Thank you very much, Steve.  I am downloading the -bios- image
now, and thanks to your pointer, I am on my way to getting 10.1
installed.

As an aside, the machine is a Fujitsu FMVS7EN7S7.  I like it because
it is compact in size and the power consumption is fairly low.
Probably important only to me, it also is made in Japan, and has a
higher ratio of Made-In-Japan components than most factory-produced
PCs.  It is a Windows 7 vintage machine, and I think one of the
earliest 64-bit machines of somewhat reasonable cost.  Because the
display is starting to fail, I want to use it as a "home server": ssh
login (text only), two-account mail server, and lightweight httpd.

Best regards to all,
Henry
