B570x NIC settings for Netware Client 32 DOS boot

I'm trying to get a new D800 (Tag CH6R851) to do a DOS boot to Client 32, so I can use Netware to connect to the server that holds the Ghost image.  This is a remote site, so the Ghost console is not an option.  The images only reside on a Netware 6.5 server.

I've got the boot to the point where the B57.LAN driver loads and an IP address is assigned.  However, when the driver loads, we get the following error:

"Please increase the min and max packet receive buffers settings"

The boot continues from there, and the rest of the Netware NLMs appear to load OK, until we get to the Client32.nlm.  We get the message that the NLM is trying to load, then it just hangs with no error.  We can't seem to get past the last NLM line.

I'm just guessing that the NIC driver message may be the problem.  Does anyone know where I can set the packet receive buffer settings?  Any other ideas?

Thanks!
