Just did some preliminary Googling, too.  From what I read of that error
code, the BIOS is returning an error code trying to copy the NIC's boot
image into "extended memory" and that this error should "never" (haha)
happen.

What happens if you take those NIC's and try them in a totally different
computer?  Any change?

The only other possibility that quickly comes to mind is the 15-16MB
memory "hole" that some BIOS's allow you to set.  This is totally a
guess, but maybe that NIC's trying to write into that memory hole, and
it can't?  I note that the error code speaks of a problem with writing
to extended memory.
