[ipxe-devel] Using iPXE to chain load Windows PE shows blank screen in Dell notebook

[Chee-Yang Chau]

Hi,

I have both PC and Dell notebook in my LAN environment.  Both PC and Dell
notebook supports PXE boot.

I attempt to chain boot into Windows PE with SanBoot iscsi target:

1. DHCP
2. undionly.kpxe
3. Press Ctrl-B to iPXE command  line
4. set keep-san 1
5. set skip-san-boot 1
6. sanboot iscsi-target
7. chain tftp://192.168.0.1/windows.pe/pxeboot.0

Boot PC using above steps does boot into Windows PE environment with iscsi
target available for Windows setup.

However, Dell notebook using same steps boot the Windows PE too, but it
doesn't show the GUI screen as what PC does.   I have tried 2 dell notebook
and both giving same result.  My Windows PE image will show a cmd windows
after loading the Windows PE.  The dell notebook doesn't show anything and
screen just blank.  I try to type exit and press enter, the notebook will
reboot.  I feel it did boot into Windows PE but doesn't show the GUI screen.

I then try another steps using PXE Linux:

1. DHCP
2. pxelinux.0
3. show menu "pxelinux.cfg/default"
4. kernel windows.pe/pxeboot.0

Both PC and Dell notebooks boot into Windows PE GUI environment and I can
see the GUI screen for notebook as well.

Both scenarios using same WinPE image.

What could cause the notebook using iPXE to chain load WinPE shows blank
after booting?

Thank you.
