[ipxe-devel] Query on UEFI iPXE boot

Hi Jarrod,
Thanks for the help.
I built the snponly.efi file.
I was using a bnx2 LOM for testing the iPXE NIC boot using UEFI. My iPXE server was hosted on a rhel5564 machine.
The iPXE client was able to successfully download the snponly.efi file. However it got stuck immediately after downloading the bootx64.efi file.
Can you please suggest if I am doing anything wrong here?
Below is the entry for the dhcpd.conf file:

Instead of targeting *specifically* the device, I'd build snponly.efi. This is akin to undionly.kkpxe.
I have successfully gotten it to work, but with some emulex firmware I've been messing with iPXE is having difficulty doing DHCP with SNP while I see no problems on any other nics (intel, broadcom, vmware's emulated intel, couple of others).
xCAT when setting up chained UEFI boot constructs the following dhcp bit (s/xNBA/iPXE/ unless using the xCAT branch):
host efitest1 {
dynamic;
hardware ethernet 42:8a:3b:42:a5:68;
supersede server.ddns-hostname = "efitest1";
supersede host-name = "efitest1";
if option user-class-identifier = "xNBA" and option
client-architecture = 00:00 {
supersede server.always-broadcast = 01;
supersede server.filename =
"http://${next-server}/tftpboot/xcat/xnba/nodes/efitest1";
} elsif option user-class-identifier = "xNBA" and option
client-architecture = 00:09 {
supersede server.filename =
"http://${next-server}/tftpboot/xcat/xnba/nodes/efitest1.uefi";
} elsif option client-architecture = 00:07 {
supersede server.filename = "xcat/xnba.efi";
} elsif option client-architecture = 00:00 {
supersede server.filename = "xcat/xnba.kpxe";
} else {
supersede server.filename = "";
}
}

Hi All,
Do we have any readme that suggests how we can execute iPXE UEFI boot?
We tried UEFI IPXE boot with an Intel igb CNA. The device ID was 10c9. We built 808610c9.efi. However while trying the UEFI iPXE boot using the .efi file we could see that the client is able to successfully download the.efi file. The client hangs after that. It never tries to get the bootx64.efi (required for booting to the EFI mode) file after that.
We were trying the UEFI boot with Sles11sp164.
Has anyone executed chain loading using iPXE in UEFI environment?
Regards
Sanjeev

8086:10de is an Intel e1000 card. You need to use the PCI IDs for your Emulex
card instead.

Emulex adapters are not (as far as I am aware) direct equivalents of Intel
e1000 adapters. You need to create an iPXE driver for Emulex adapters (or pay
to have one created).
