Sam,

Could you try changing your dhpcd.conf entry to look like:

class "machinesIcareabout"{
         match substring ( hardware, 1,3);
         if substring (option vendor-class-identifier, 0,9) =  
"Etherboot" {
                 filename "pxelinux.0";
         } else if substring (option vendor-class-identifier, 0,9) =  
"PXEClient" {
                 filename "eepro100.zpxe";
         }
}

subclass "machinesIcareabout" 00:13:20;

--

Then create the directory /tftpboot/pxelinux.cfg

and place the following lines in a file called  
/tftpboot/pxelinux.cfg/default:

prompt 0
default 0
label 0
     kernel memtest

You will also need to get a recent copy of pxelinux.0 to put in  
/tftpboot

You should be able to get one here:

     http://www.kernel.org/pub/linux/utils/boot/syslinux/

The latest one right now is:

      
http://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux 
-3.07.tar.gz

You can extract pxelinux.0 from the tar file by unpacking it with:

     tar -zxf syslinux-3.07.tar.gz

Then just copy the file to /tftpboot with something like:

     cp syslinux-3.07/pxelinux.0 /tftpboot

What I'm trying to do here is to determine if there is a problem with  
mknbi and if pxelinux will load memtest in this scenario.

Since pxelinux does menus, you may be able to entries in the  
/tftpboot/pxelinux.cfg/default file to get the functionality you need.

Thanks for doing this testing.  I look forward to hearing what happens.
