3Com have a ftp site at ftp.3com.com.  The program crdfnd.exe detects their
boards and prints out the boards configuration. It can be found in:

adapters/drivers/crdfnd.exe

Hopefully it will detect the 3c501 card.

Below is a description of how I go a NetBSD-current machine to boot
diskless from another.

On the Server:

1. To get rarpd working:

	Enable in in /etc/netstart, eg. rarpd_flags="-a"

	Create a directory /tftpboot

	Create a file /tftpboot/{ip}, where {ip} is the ip address in 
	uppercase hexadecimal.  eg. for the IP number 136.186.128.3 create
	the file /tftpboot/88BA8003
  
	Create an /etc/ethers file with an entry for the client machine, eg:
		aa:bb:cc:ee:ff:gg	client-name

		where aa:bb:cc:ee:ff:gg is the client's ethernet address.


2. Get rpc.bootparamd working

	Enable rpc.bootparamd in /etc/netstart

	Create an /etc/bootparams file with an entry for the remote machine:
	
	eg.
	client-name  root=server-name:/home/client-root \
		swap=server-name:/home/client-swap

3. Create a file for swap, and setup a root directory for the client.

This worked for me, hope it helps.
