installation problem

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

I have two, supposedly identical nettop-style Lenovo machines.   They
are intended for use as headless mail/DNS servers etc.   On one of
them I installed 6.1.4 from a disk image on a USB disk without
difficulty, worked first time, been running for months without a
problem.

The other, however, despite installing apparently normally, will not
boot.   I used the same procedure, the same USB disk, but on startup
it drops to the boot prompt, having apparently failed to find a
bootable kernel.   'ls' returns a blank.   But I can boot from 6.1.4
installed on a USB disk, using 'boot hd1a/netbsd', and then mount
/dev/wd0a which appears to be fine, with /netbsd in place.

I assume that something is amiss with the configuration of the disk at
a lower level than I am used to dealing with.   In case it helps, I am
attaching the ouput of 'disklabel wd0' for both machines: 'viking' is
the one that works normally, 'utsire' fails to boot.
