Second attempt:

now I see what is going on. The very first time after building the
boot diskette, the file nvram.txt with the boot parameters, is not
there yet. So this system call tries to open this file and fails.
After you supply the boot parameters by hand, they are written to this
file, and the next time you boot after that, the error message should
not happen.

So, this error message should not cause any problems.
