[K12OSN] need bootrom/etherboot for Compaq net1/33s

[Petre Scheie]

I think Tim was trying to say that the 3c515 is the only supported ISA 10/100mb card, 
since 100mb to the client is usually recommended, and that even then, because of ISA bus 
limitations, you won't get 100mb. (There weren't many 100mb ISA cards made for just this 
reason.) You are correct, that Etherlink IIIs will work, but only at 10mb, although that 
can be adequate as others have said.  I still have a few 10mb Etherlink IIIs in use. 
However, while most switches will drop to 10mb if that's what the NIC speed is, I have 
found that with later releases of LTSP the terminals/clients have trouble booting when 
connected this way.  As such, if I have 10mb cards in my clients, I make it a point to 
connect them to a 10mb hub (yes, I still have some of those) which then connects to my 
main 100mb switch.  Plus, I had to put some special settings, courtesy of Jim McQ, into 
/etc/dhcpd.conf (which you have to do anyway with ISA cards).  Here's the relevant chunk 
from dhcpd.conf:

host wendolene {
         hardware ethernet     00:20:AF:14:DB:0B;
         fixed-address         172.26.18.5;
         filename              "/lts/vmlinuz.ltsp";
         option option-128 e4:45:74:68:00:00;
         option option-129 "NIC=3c509 MOPTS=nolock,ro,wsize=2048,rsize=2048";
     }

It's the "MOPTS=..." part that is necessary anymore with 10mb clients.  HTH
