I'm trying to jumpstart a Blade 2500 on a classless subnet with the command:

boot net:netmask=255.255.255.128 - install w

like I have countless times in the past with other workstations, but
this time I'm getting the error:

unknown key 'netmask'

The OpenBoot version is 4.17.1. I've tried a "reset-all" and I've
verified the net alias is correct.

Has anyone ever come across this? What's the fix?


Thanks,
Roy
