I have a Net Dimm version 2.13. I've read for this version the Dimm has 'allnet' features but it won't net boot. I've put in the IP address for net boot settings and set the jumpers and it's giving me an error message - so this appears true. The netdimm works fine in GDROM mode. I can see the only way to rectify this is by upgrading the Net dimm to version 3.17. I have acquired the relevant key chip but need the GDROM GDS-0023E. Is it possible to make a copy of the GDROM until an original GDROM turns up?
