H2+ PXE Falining: Update Firmware?

Post by rvalle »

Hi!

I have setup MAAS to deploy H2s. The H2s work fine but the H2+ fails most of the PXE boots.

Some do work. I think there is more probability after could power on, and after saving the BIOS settings.

However, most of them fail.

As a first try I would like to update the Firmware of the Realtek adapter.

Anybody knows how to do this?

@Realtek there is PXE ROM, but the instructions talk about an utility to change name of the driver, and not about how to install it.

The UEFI driver is also out of date, and a newer one can be downloaded @Realtek, however, there is no information on how to install it.

Any idea about this?

Anybody has PXE working reliably on the H2?

Since the H2 and H2+ have used the same Realtek RTL8125B chipset, I don't think the UEFI driver could be a root cause.

Anyway, because we have no experience of using the PXE boot on the H2/H2+, I hope other experts can help you.

The updated driver seems to be an efi image, I wonder if you can just boot it from your pxe/dhcp server? upload it and set DHCP option 067 to the name of the file.

You could maybe also try to set fast boot as disabled if not already (boot options in H2+ BIOS) and set the setup timeout a little higher on the same screen. Try to give it some more time to get an IP and response from DHCP/PXE server.

thanks @brad.

Actually, I have made some changes that make PXE work better:

- Introduce 2 seconds of ESC timeout, hoping that the time allows for better Network Interface initialization.
- Disabled ASPM on both PICe lines as other post suggests.

Now PXE is somehow more reliable. However, it is taking a long time sometimes.
