[SOLVED] tftpboot and AMD Ryzen

Beitragvon Gabriele » 03 Okt 2018, 10:10

Hello,

recently we bought a Lenovo 20MU000CGE laptop with AMD Ryzen 5 Pro 2500U processor to evaluate the possibility of using it instead of Intel systems.

The laptop works well with both windows 10 and kubuntu 18.04.1 (need to add the boot options "noacpi” and “nomodeset" on kernel boot) if installed manually and we are satisfied with the performance, but has problems with installation via netboot using the OPSI server.

I follow this step (for intel systems work correctly):
- disabled the secure boot and set the legacy boot in the UEFI BIOS
- booting via PXE is successful and shows the elilo(?) boot screen of the OPSI server
- select the line and start the boot
- "loading install" completed correctly
- here the problem: “loading miniroot-x64.bz2" starts and shows about two lines of dots then returns to the elilo(?) boot screen of the OPSI server (does not get the message "ready" and not start the image)

I tried to modify in various ways the file "/tftpboot/linux/pxelinux.cfg/default.menu" to see if it changed anything but without finding a solution and not see any error on screen.

I think the problem is the "miniroot" image but I'm not sure, any help are welcome because I have no other ideas.

This is the "default.menu" file:

Hi
the bootimage in UEFI works diferent than on MBR mode
in MBR mode we have a menu, where you can edit things like you did.
In UEFI mode this is not possible.
Hereby when a netboot product is set to setup and the first UEFI boot device is Ethernet, the bootimage is loaded. The bootimage changes the UEFI boot order to either boot a WINPE, in case you install a windows, or the installed Linux.

So in order to boot your client in UEFI mode, you have to set your ethernet Device as boot device #1 in the UEFI. In Addition oyu have to set the 'Uefi Boot' option in opsi and set a product on setup, then the bootimage should boot fine.

Cheers
Mathias

Hello Mathias,
thanks for the answer, I write to info(at)uib.de and ask to have a trial "etc/opsi/modules" file with the support of the UEFI boot that at the moment we do not have and until now we have always used the legacy mode without problems.

I let you know if it resolves.

Hi
last Tuesday I received the trial license and verified that using the UEFI mode of the PXE the problem don’t show up, so this is a possible solution.

However, colleagues and I prefer to manage the installation directly from the client PC instead of having to create it by hand in the backend, entering the MAC address... then I invest more times to understand the problem with the legacy mode and finaly I managed to generate an error message related to the amount of RAM available.
So I also fixed it in legacy mode by specifying in the boot options of the miniroot the amount of RAM it should use.

Code: Alles auswählen

append initrd=miniroot.bz2 mem=2048M ...

That doesn't sound like it's working like it should.

Wait, you mean you can't register new clients on the client itself via the boot menu (in UEFI mode)?
Bitte schreiben Sie Deutsch, when I'm responding in the German-speaking part of the forum!

Hi,

there isn't a default menu present in UEFI netboot. While UEFI netboot appears to be the same as PXE it certainly is not.
To have clients boot into the bootimage you'd have to set a netboot product for a client to setup.

What you could do is use an USB stick prepared with the ISO of the bootimage to boot from on a client.


Cheers

Niko
