I too am very curious about how to do something like this.

I would like to boot dos boot images to configure hardware ( bios, raid, 
etc ) before the OS gets loaded.  However, updating to the next stage of 
the process is the hard part. 

I can hack it from the tftp side, but it would be nicer to handle it in 
the client so you could add logic to only do the update if the bios 
flash, etc was successful and reboot.

Is there a reasonable tcpip stack available for DOS ( and some basic 
utilities like a dhcp client, reboot, wget ) that could be used to 
manage this?
