freebsd-questions:
I tried to do the simplest install I could onto one USB flash drive:
"Welcome to FreeBSD" -- choose "1. Boot Multi User".
"Welcome" -- choose "Install".
"Keymap Selection" -- choose ">>> Continue with default keymap".
"Set Hostname" -- enter "cd2533".
"Distribution Select" -- accept default selections:
games
ports
"Partitioning" -- select "Auto (UFS)":
Choose "da0 15 GB Disk <SanDisk Ultra Fit>"
Choose "Entire Disk", "Yes", "Finish", "Commit".
Enter and confirm root password.
"Network Configuration":
Select "em0"
"IPv4" -- "YES".
"DHCP" -- "YES".
"IPv6" -- "NO".
"Resolver Configuration"
"Search" -- holgerdamske.com
"IPv4 DNS 1" -- 192.168.1.1
"IPv4 DNS 2" --
"Set Local or UTC Clock" -- "YES".
"Time Zone Selector" -- "America North and South" -- "United
"States" -- "Pacific Time". Confirm "PST".
"System Configuration" -- select:
sshd
ntpd
powerd
dumpdev
"Add User Accounts" -- "NO".
"Final Configuration" -- "Exit".
"Manual Configuration" -- "NO".
"Complete" -- "Reboot".
Power down. Remove installation media. Power-up -- nope.
It appears that the BIOS does not think the USB flash drive is bootable.
Put USB flash drive into Linux box:

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Put USB drive back into cd2533 and try again -- it works!
So, it appears that there is a bug in the BSD installer -- it is not
setting the boot flag in the protective MBR partition table (?).
