>Description:

I wanted to upgrade the firmware in my machine, which has only NetBSD installed.
Following the README file that comes with the standalone flash upgrade tool,
I copied it to my root partition and tried to boot it. I noticed I had to
rename it (see PR 18691), but even then it was not loadable.

 loadfile: reading header
 unknown executable format
 Program terminated
 ok 
 
 I had to borrow a Solaris network bootblock from a friend and set up a network 
 boot server with NFS root and put the firmware update there. This was double
 luck (found bootblock, network server available), and pretty inconvenient.
 
 If I'd had a CD rom I might have found a bootable Solaris CD and go on from there,
 but I have no CD rom drive in this machine nor a bootable Solaris CD.
 
 Fixing loadfile() to accept this binary is probably not very hard, and would
 help NetBSD users w/o Solaris.
 
 Here is some info on the binary:
