ASIX AX88772A initialization failed

[Jeff Turley]

I am attempting to boot fog on a Lenovo Thinkpad with a Sabrent USB NIC. ASIX AX88772A is the description on the PXE boot screen. I have USB 3.0 disabled in the BIOS. PXE boot works and ipxe attempts to initialize the driver. After about 15 seconds it failed to initialize AX88772B. I have tried 10 or 11 different kernels same think with all of them.

Kernel’s aren’t the problem. You could try other “undionly” files within the tftp folder.

There’s
undionly.pxe
undionly.kpxe (This is the default)
undionly.kkpxe
ipxe.pxe
ipxe.kpxe
ipxe.kkpxe

Try one of the ipxe.* files as your undionly and maybe they’ll be success?

undionly.kkpxe worked it was the last one i tried, I was getting nervous. What is the diffrence between these files. Thanks

[Junkhacker]

the differences between those files and what the naming conventions mean are complicated and poorly documented, unfortunately.

undionly.x files are universal configurations
ipxe.x files contain a lot of hardware specific drivers that may or may not work better then a universal build, depending on your hardware.

I don’t know of a good method to distinguish besides the undi/ipxe files nor the pxe, kpxe, and kkpxe files extentions. I wrote about them somewhere but can’t remember where.

What I do know,
ipxe has drivers, undionly uses the “undi” stack made by the manufacturer.

pxe unloads undi and pxe stack.
kpxe unloads just the pxe stack
kkpxe keeps both undi and pxe stacks in place.

kkpxe works best for buggy hardware. Only recommended if you’re having weird issues with the undionly.kpxe
kpxe is the normal file we want in use as it seems to be the best between pxe/chaining I can find without flashing roms.
pxe is ultimately the goal, but there’s not enough information to allow this to actually work flawlessly everytime.

Used some info that has been thrown around about these files and checked on a few other sites and threw this together. This should cover most questions on PXE and iPXE along with the different file types.
