Hi philip & ipxe owner??
Thanks for your helpful reply and hard work.
I have changed the code like your tip,and built snponly.efi,run snponly.efi
under uefi shell,it can detecte the network device and chain the web
http://boot.ipxe.org/demo/boot.php succeed,but loadimage failture because the
file is not uefi image,how do you solve this problem.
I have some questions,could you help to answer?I really want to research ipxe
and import to our project.
1.Do you know how to buid a uefi boot os image,i can't find the solution to
buid a os image,i hope the os image can boot via ipxe under uefi enviroment.
2.run snponly.efi and then run sanboot comand,"can't open san device " error
was showed because ipxe have not implement under uefi,what is your solution.
3.ipxe.efi/$dirver.efi still can't detect network devcie under,what is your
solution.
4.If you can provide your tips or solution will be best.
5.Do you know why ipxe.efi or $driver.efi can't open pci protocol and then
can't enum pci device.
the key code is efi_supported()->efi_create() in efi_pci.c.
if ( ( efirc = bs->OpenProtocol ( device,
&efi_pci_io_protocol_guid,
&pci_io.interface,
efidrv->driver.DriverBindingHandle,
device,
EFI_OPEN_PROTOCOL_BY_DRIVER )) !=0 ){
DBGCP ( efipci, "EFIPCI device %p is not a PCI device\n",
device );
goto err_open_protocol;
}

Subject: IPXE question: iPXE.efi can't detect network device
Hi Philip,
After read your topic about "Using iPXE with UNDI driver" in UEFI enviroment,i
think that you have built a *.efi file and the file can connect network
device,so could you tell me your step,
In your topic,you said that "Thanks! This is what I did. I changed snpbus_probe
to call LocateHandle to find a handle that supports SNP and it now connects to
my driver",how you are call LocateHandle?
I will eagerly waitting for your reply,best your regeards.

????: IPXE question: iPXE.efi can't detect network device
Dear IPXE owner,
Thanks for ipxe develop team hard work,after read ipxe code ,i found that ipxe
code is very classic and helpful to me.
Our product will import ipxe,but efi file can't found network device,I built
efi file according to the below steps.
1.I have undef PXE_STACK and PXE_MENU in src\config\general.h.
2.Built EFI version as vendor/product specific:
$ make bin-x86-64/10222000.efi bin-x86-64/10222001.efi
bin-x86-64/10222625.efi.(computer vendor is 1022 ,device id is 2001).
$make bin-x86-64-efi/80861502(computer vendor is 8086,device id is 1502).
3.insert usb drive and enter uefi shell.
4.fs0:
5.run above efi file.
6.All commands are Show the tip "No more network devices".
My built enviroment like following:
OS:ubuntu 12
GCC:4.6

Hello.
It's better to address this question directly to the [email protected]
mailing list. Michael Brown should be right person.
BTW, ipxe.iso is legacy bootable ISO image and it contains all supported
network drivers including pcnet32.
Try to build EFI version as vendor/product specific:
$ make bin-x86-64/10222000.efi bin-x86-64/10222001.efi bin-x86-64/10222625.efi
One of them should work.
Please pay attention that EFI environment doesn't support PXE stack. You have
to disable PXE_STACK and PXE_MENU in the config file.

Dear Anton,
I have built ipxe.efi 64 bit,my network device card is pcnet32,but ipxe.efi
can't attach network card,i only get the log "No more network devices".but if
boot to ipxe via ipxe.iso,ipxe can detected the network device card.
We will add ipxe to our project,so I hurry to solve this problem.
BTW,
After debug ipxe.efi,i found that only call efi_pci.c\efipci_driver_startup but
not call efi_pci.c\efipci_start,so i think pci device not been attach,do you
know that what time to call function efipci_start().
Although I have read a topic about "Using iPXE with UNDI driver",but i can't
find the root cause,Do you know the root cause??
Thank you very much.
I have built via run command "make bin-x86-64/ipxe.efi DEBUG:efi_pci
device,pci" and then run ipxe.efi,
unfortunately,the result like following figure,it means can't attach any pci
device,do you know why?_______________________________________________
