Dnsmasq bios and uefi
-
@KnightRaven Yeah, I see the issue right away. When you are back on this project create a new thread and we can work through what needs to be done. You are missing a few lines that make the uefi bit work.

hi, when saw dnsmasq maillist http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2017q2/011379.html
3q for https://github.com/openSUSE/kiwi/wiki/Setup-PXE-boot-with-EFI-using-grub2 & https://www.ibm.com/developerworks/community/blogs/a2674a1d-a968-4f17-998f-b8b38497c9f7/entry/uefi-grub2?lang=ru
the problem may not in dnsmasq, when update to version 2.76. uefi boot can see grub>

It’s not perfect.
Cuz in grub.cfg we need write nextserver ip & host ip,
And grub2-mkstandalone command write grub.cfg in bootx64.efi, cuz I change boot/grub/grub.cfg it’s. not working.
So now I working to grub lib, want find way to solve this 3 problem.If anybody working with grub/grub2, can give me some idea? thank you very much.***

@xutianhong of just use refind which is meant to automatically use EFI?

@Tom-Elliott hi, i just google what is rEFInd. dose rEFInd support BIOS/EFI pxeboot?
-
@xutianhong I’m not sure I follow. Grub and rEFInd are exit types, to leave pxe and boot to HDD.
-
If you’re simply trying to boot an iso, ipxe supports this natively.

@Tom-Elliott very thank you. im try to test rEFInd to make sure is it suit for my env. i will reply later.

@Tom-Elliott thank you for ur advice, i found some figure way @ipxe site. now im search way to kindly combine ipxe with cobbler. the uefi ipxe boot install cost me lots of time cuz rhel73 have kernel bug. finally figure out too.

@xutianhong Can you explain what your trouble is? I read your first post and it was not clear, I think maybe the language translation.
Your first post make me think you are telling us what you find not asking for help.

@george1421 ok. i was using cobbler install redhat @ my work env. at first i found all works fine @ legacy bios. but when shift to UEFI. its’ not work good anymore. cobbler+dnsmasq.proxymode, msg freeze at option 47. i search google and found fog.wiki have advice dnsmasq need upgrade to 2.76. i do it. at this time , screen show grub>. then i search @ dnsmasq mail list and other website. find some way to figure this write in my first post. but it’s need write static ip&nextserver info to cfg, make standalone efi file. then Tom Elliott suggest ipxe & rEFInd.
-
@george1421 im sorry make u confuse, cuz my english was not good. maybe can’t describe clearly.

@xutianhong said in Dnsmasq bios and uefi:

What confuses me is you say dnsmasq and then grub. This is the confusion. dnsmasq is used to send the proper boot information to the target computer to get the target to load the FOG iPXE menu. Once the iPXE menu is displayed dnsmasq is no longer needed.
Once the iPXE menu is displayed you must make a menu pick within a few seconds or the iPXE menu picks boot from local hard drive to boot.
This is where the iPXE menu uses the (default) sanboot process for finding the hard drive on bios (legacy) computers. If your target computer is uefi then you can use grub, but most will use rEFInd to identify the boot partition on the hard drive. If rEFInd can’t find the boot partition you may need to adjust the refind.conf file to search more locations.
I want to be clear that if your target computer boots into the FOG iPXE menu then dnsmasq is working correctly.
If you are having a problem leaving the iPXE menu and booting from the local hard drive then this is an iPXE problem.

We can work together to find an answer, so no problem. We will take it slow to understand each other.

@george1421 im not sure what happened. it’s looks like grub cant get cfg file?
it’s my boot process.
dhcp start @ 200
tftp & dnsmasq.proxymode start @ 226 only use pxe+grub not ipxe&refind
uefi client @ dhcp

@xutianhong what does the grub.conf look like?
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

@xutianhong I say this because it appears from your directory tree there is no grub.cfg file.
-
@Tom-Elliott there no grub.cfg, only cobbler gen efidefault. ofcuz i copy efidefault to /grub.cfg & /boot/grub/grub.cfg, not work, same grub> msg.

@xutianhong and what does your grub line look like?
I would imagine it needs to look at the config file directly.
I don’t know if it can be done in dnsmasq but possibly:
pxe-service=BC_EFI,"BC_EFI","grub/grub-x86_64.efi --config-file=grub/efidefault",192.168.136.226 -
@xutianhong I have to ask are you using FOG or are you using FOG for pxe only, or are you not using fog and have a question about pxe booting?
I would ask why you do it this way? I would not use grub but the iPXE menu instead.
-
@george1421 im not using FOG. only question about pxe booting. use this cuz cobbler default env. im not add/del extra file to it. if default can work. i dont want change any thing.
