[Simh] trouble selecting VAX ethernet on CentOS

[Mark Pizzolato - Info Comm]

Hi Mike,

I just fixed something in the BuildROMs code.  I've added checks to verify that the files have been unpacked correctly.  Can you try again.

If the make fails again it should issue an error message explaining why instead of the segfault.  This error message will indicate that the ROM image files have been mangled.  This is likely due to something trying to do line ending conversions which isn't appropriate for the binary ROM files.

My explicit instructions to download the zip file and then to unpack it with 'unzip -aa zipfilename.zip' have worked correctly for me on many platforms.

Please let me know if you get any further.

Thanks.

- Mark
