Hi,

I am also trying to setup PXE for IA64. Could you send a copy of your
pxe.conf file to me? And the boot strap you are using?  Thanks. 

Best regards
Jack

I suggest you use elilo-3.4 instead of 3.0. The package contains an
example of the dcph/pxe setup I used to test this. The problem was
that the ISC DHCPD needed some extensions to support PXE/Ia64. Those
extensions were added by Intel but I don't know if they ever made it
into the official ISC DHCPD server, you'd have to check.

Anyway, in the elilo-3.4 package, go to examples/netboot. You'll
find a PXE config file.

Hope this helps.

PS: Brett Johnson is the new maintainer of the package and he has setup 
a SourceForge web for elilo: http://elilo.sf.net

Thank you. But I am using the PXE of a RedHat 9.0. So do you know if
this PXE server can support IA64? Do you have a sample pxe.conf for the
PXE server?

I don't have a redhat9 machine, but based on what I see on rpmfind.net,
it looks like they're using dhcp 3.0p1, which should work fine.

As Stephane mentioned, there is an example config in the elilo
"netbooting.txt" document.  You can get it from

http://cvs.sourceforge.net/viewcvs.py/elilo/elilo/docs/netbooting.txt

If you don't have a local copy.

Cheers!

I don't have access to the DHCP server. I can only configure the PXE
server which is full under my control. I don't think the dhcpd-pxe.conf
can be used for the RedHat PXE server (pxe-0.1-36). Right?

Best regards

Well,that I don't know. You'd have to look at the example and compare
it with the documentation of the RedHat server. I doubt they match.

No, the config files are quite different.  I don't know if the pxe
server will boot an ia64 machine, since I've never tried it.  Googleing
around, I found a sample pxe config in the mandrake docs, which actually
has the token "IA64EFI" in it.  I have no clue what the token means, but
it has all the right letters :o)

I've tried that before. It is a different PXE implementation other than
the one in RedHat. Anyway, thanks you all. :)

[Linux-ia64] elilo-3.0 PXE mode fix

[Stephane Eranian]

[-- Attachment #1: Type: text/plain, Size: 326 bytes --]

Hi,

I have identified a problem causing elilo to fail when netbooting from 
a PXE server. Due to a stupid mistake on my part, the config file was
set to the kernel image file when querying the PXE layers.

This problem DOES NOT affect netbooting using regular DHCP server.

The fix is attached to this E-mail.
