Stuck on initialising devices

[2cfg]

Quote: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
