I am sending LTC to your same address, just like last time.

That it boots 32bit and not 64bit is intriguing,
as the 64bit version seems to have the 32bit UEFI
(/efi/boot/bootia32.efi in the AntiX-16_x64-full.iso package).
Is there any possibility it is not booting UEFI ?
I used USB-creator which does some fancy ISO magic,
and although it seems unlikely,
is there a chance the tablet is falling back to booting bios not UEFI?
More on that at the end below...

First:
The tools can show whether the wifi was even detected
(like the display below of Antix Control Center - Full Info page)
If the device is detected and merely misconfigured it would be golden.
Perhaps the device is requiring a 64bit driver for wifi,
which could be where it goes off the rails.
In the first Baytrail chips the device drivers needed to be 32bit,
but it may be that by now everything is expecting 64bit - or not!?!

Rotating the screen on these things is always a challenge,
there are many things that get cast in stone during the boot process.

It may be that sound is a hopeless cause.
Finding the sound device then getting it to cooperate with Pulse
probably requires an act of God.

Everything hinges on getting wifi to work,
because if wifi can be made to work (no dongles!)
then anything can be fixed eventually.
Without wifi a tablet can be extremely difficult to update or even use.
With my Iconia I could use the 3g but it was excruciating frustration.

The first thing I see in the HP forums is a bit daunting:

The HP forums are a bit intimidating to read,
but I always have a bit more optimism that things can be sorted
if enough handles exist in the system.
The grief windows users sometimes experience can be either
illuminating or hopefully irrelevant once a linux distro works.
I would, however be extremely leery of doing anything
to change, upgrade or downgrade the BIOS,
because such things can go terminally broken.
