Okay, sounds fine.

Ummm.  okay, so I need to make an elf-enabled floppy disk image?

I agree 8)

Only when I pull the blade out and manually hook a floppy drive to it so
I can re-flash the bios.

But getting back on track, am I doing this sequence improperly?

On the boot host...
cd /usr/src/linux[whatever]
make bzImage
I end up with an arch/x86_64/boot/bzImage bootable image.
cp arch/x86_64/boot/bzImage /tftpboot
~/src/mkelfImage-2.5/objdir/sbin/mkelfImage --kernel=/tftpboot/bzImage
I alter dhcpd.conf to have 'filename "test1"'

I restart dhcpd, restart the blade.

Note the Etherboot header says:

Loading Etherboot version: 5.2.4
ROM segment 0x0000 length 0x0000 reloc 0x00000000
CPU 2063mhz
Etherboot 4.2.5( (GPL)... Tagged ELF for [IDE][TG3]    <-- okay?
Relocating _text from...
Boot from (N)etwork....

After selecting 'boot from Network'

I get
_Probing pci nic...
[ptg3-5704]Ethernet add...
Tigon3 [partno...
Link is up..
Searching for server
Me: (addresses)
Loading (ELF)... done
Firmware type: LinuxBIOS

(note the ' ' before the cursor) - at this point it's hung.

Is this the right process?
