Hi Siyuan,
When I add that option to the file, UEFI complains "PXE-E16: No offer
received.\n".
I can see that DHCP server did reply to the request and the packet is received
but UEFI is not happy.
Here is the packet exchange.

Hi, Chris
Just add
"option vendor-class-identifier "PXEClient";" to your dhcpd.conf file, it will
enable option 60.
Best Regards,

Subject: [edk2] PXE Boot Error
Hi All,
I am trying to boot an ARM core using PXE boot and I am following the steps
mentioned in this Linaro wiki
(https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/UEFI_Network_Booting).
Most importantly, the DHCP server configuration part of it. It says:
Add these lines to /etc/dhcp/dhcpd.conf:
allow booting;
allow bootp;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.3 192.168.0.253;
}
host rtsm {
hardware ethernet 00:02:f7:ef:5c:f5;
fixed-address 192.168.0.20;
option host-name "rtsm";
next-server 192.168.0.1;
filename "efi/grub.efi";
}
When I do configure the UEFI boot manager to boot, I get error in
"PxeBcSelectBootPrompt" function at the following check:
if (Packet->OfferType != DHCP4_PACKET_TYPE_PXE10) {
return EFI_NOT_FOUND;
}
Seems like the DHCP server is offering "DHCP4_PACKET_TYPE_DHCP_ONLY" and not
"DHCP4_PACKET_TYPE_PXE10".
After looking around, it seems I need to enable option 060 in DHCP server. I
have not been able to find a way to configure
the DHCP to allow PXE boot. The most popular configuration change suggested was
"option vendor-class-identifier "PXEClient";".
Any suggestions ?
Thanx.
