Fog 1.3.0 : PB with Mac NetBoot

[Tom Elliott]

@dfuriet The messages appear clear to me. At least in the last picture. Essentially, it’s unable to bring the nic up to actually try and use it.

Have you tried entering the iPXE shell and just waiting for about 30 sends, then try to configure by running the command dhcp?

[Sebastian Roth]

@dfuriet Did you see the postings in the iPXE forum? We are trying to gather more information and surely hope to fix things for both iMac14,1 and iMac17,1 but it will be a long way I suppose.

Could you try out something for us? As Tom said, could you enter the shell when you see the message on screen (“DHCP failed, hit 's' for the iPXE shell; ...”). There type the following commands and take a picture:

ipxe> dhcp
...
ipxe> ifstat

After the first command (dhcp) you’ll need to wait for some seconds and might see the same errors as before. The type the ifstat command and take a picture of it all.

On my iMac14,1, I can’t go into the menu because there a no errror showing, only banner text :

iPXE initialising device...ok

iPXE 1.0.0+ (26050) -- Open Source Network Boot Firmware -- http://ipxe.org
Features : DNS FTP HTTPS iSCSI NFS TFTP SRP VLAN AoE EFI Menu

then crashed with nothing else

Sometime I have more, like my first (reversed) picture

My second picture is on a iMac17,1, but I don’t have it anymore

Immediately after banner text is displayed, Ethernet Card power off a few seconds, then Ethernet Card power on… It’s at this time that ipxe crash

Hello,

I have exactly the same problem !
Yesterday, I update one iMac with apple store. When finished I Tried to upload image and can’t boot on PXE. It’s freezing.

I tried this morning to download image on another iMac and it works.

I think it’s a bios update in the lasts macOs updates who makes the problem …

When it comes to Macs I’m a bit ignorant so this question may be off point. Is there an option to roll back the bios update or is that tied to the macOS you are currently running.

For documentation purposes, can you post the version of the bios/firmware that is working and the version that stops working?

Thank you for adding a bit of clarity to this issue too!!

@Imperilled thank you for helping us draw a clear line in the sand between working and not working!!

[Imperilled]

@george1421 if it can help. I boot on snp.efi. ipxe.efi never working on my machines.

Any news for ipxe problem ?

[Tom Elliott]

@dfuriet have you tried the latest version of fog? I don’t expect any difference but ipxe has pushed a few updates since 1.3.0 released.

[Sebastian Roth]

@dfuriet @Imperilled Ok, I got some new advice from the iPXE devs. Debugging the actual driver issue won’t be easy and will therefore take too many round trips of “try this binary and report again”.

Nevertheless we ought to try out using the SNP binary (debug enabled - DEBUG=snp:3,nii:3 to start with). So find 01_snp.efi here. Just give it a try and post pictures or video. Make sure when you take those to place the camera or phone on a stack of books in front of the screen so we have a good picture.
