iPXE discussion forum

Hi!
I have problem with initialising iPXE when i boot this from Grub2 menuentry:

Code:

menuentry "WinPE" {

  linux16 (tftp)/ipxe.lkrn

  initrd16 (tftp)/boot/pxe/boot.ipxe

}

Grub2 is booted over the TFTP and invoke the iPXE kernel to load in a chain to load the WinPE.

I compiled the iPXE in debug mode and found that the freeze occurs at the PCI bus stage.
I also found that iPXE is loading if I disconnect SATA drives.

Can you help me to resolve this problem?

Grab all lines that has "Ethernet" on them, or just take the whole bunch so that we can see your PCI layout.

Another thing that you probably should try is, first of course to make sure you are using the latest version of iPXE.
But you should also try to boot it directly from a USB stick, both grub and syslinux are known to have caused issues in the past.

Yes, I use last version from http://boot.ipxe.org/

ipxe.usb work properly.

As I wrote above, iPXE also boots through the grub if I disconnect the SATA disks.

I use the following boot chain order:
PXE -> DHCP
filename "boot/grub/i386-pc/core.0" from TFTP
grub.cfg from TFTP
ipxe.lkrn from TFTP
