I am glad to hear that you are able to use the tlan Etherboot driver I wrote. > The only hardware difference I know of between the DCs is that > the good one has a 200MHz processor while the sluggish ones have > 133MHz processors.

It's been a while since I used a tlan card. Does the revision number still display when Etherboot loads? If they are different revisions it is possible that a different reset is necessary as Etherboot exits. Half-Duplex could certainly a cause the slowness but only if the hub or switch is connected at Full duplex. What does Etherboot report as it loads on those clients? Full or half Duplex? > I want to force the NIC to use FULL_DUPLEX.

Once you get a kernel that will work via Etherboot then look at how to change the options. > " The following lines in the /etc/dhcpd.conf file should do the > trick: > > option option-128 e4:45:74:68:00:00; > option option-129 "NIC=ne IO=0x300"; Ken, if you are reading - How does this work again? I tried to explain it to some one the other day but became confused. I believe that option 128 is a Hex representation that Etherboot understands to mean that there are some options that it should pass to the kernel. Option 129 are those options. > I'm a bit confused on these option lines. Is option-128 a > replacement for the "hardware ethernet" setting for the MAC > address of the client's NIC? No, see above. > option-129 looks like it would be something like "NIC=tlan ..." > What words are reserved for setting the duplex ... DUPLEX=full? > Can I set duplex from within the dhcpd.conf file? Yes, NIC=tlan ... should work. ;-) I have no idea what should come after it though.
