HTTP Boot anyone?

Post by Paul21 » 2021/10/15 12:46:18

Hello,
Long time reader, first post...

Having some trouble getting UEFI HTTP boot to install CentOS7. I basically used same directory structure as in PXE/TFTP and created a basic grub.cg. It loads fine but has trouble finding the disk to mount. Panic messages are...

"No filesystem could mount root, tried:"
"VFS: Unable to mount root fs on unkown-block(0,0)"

I'm using the /images/pxeboot/initrd,vmlinuz so I'm guessing they won't work for HTTP boot?
Anyone have any luck with this?
I found an old thread but no resolution: viewtopic.php?f=47&t=75950

TIA,
Paul

In case this helps someone...

Not sure if we're missing some critical syntax in grub.cfg to make this work but, we had luck with using SUSE's bootx64.efi file. Seems they have patched theirs to work with HTTP boot. I came across this...

Anyway, if anyone got the standard CentOS 7 file to work, let me know.

Thanks,
Paul
