Oops - that should have been
https://people.freebsd.org/~emaste/mini-image-2018-05-28-amd64.xz

But the most recent snapshot images have been built the same way now:

That gives a 404.

I have the strong suspision that your previous image doesn't get recognized as
bootable because the C/H/S values are not filled in.

At least it's not a regression.

Strange. Can you try an updated test image of mine
(https://people.freebsd.org/~emaste/mini-image-2018-05-28.xz) or this
week's -CURRENT snapshot?

I have bad news and some good news.

The bad news is that with this image the USB stick doesn't get recognized as
a boot device. Same as with the 11.2-BETA2 images.

The good news is that if I completely recreate the MBR, keeping the layout of
the partitions the same, then the USB stick is recognized.

The weird news is that it then proceeds to boot from harddisk. But that may
be an issue with the boot code I put on.

So the issue is limited to the MBR. 

I'll try to figure out what exactly makes the difference.

Ed,
I tested this here on my R710 that was failing to boot in
Bios mode with the amd64-11.2-Beta2 disc1.iso, your
mini-image boots fine in either Bios or UEFI mode
on  my Dell R710, so what ever you did fixed at
least my one data point.

Tested successfully on Dell Latitude E7450 for both legacy BIOS and UEFI
boot mode.

Can you download the image from
https://people.freebsd.org/~emaste/mini-image.amd64.xz, uncompress and
write it to a USB stick and try on this system? This is a
MBR-partitioned dual-mode test image. It's not an installer - it
should just boot to a login prompt - but can be used to test this
scheme.

Re: Boot USB memstick with MBR (WAS: Re: [RFC] Deprecation and removal of the drm2 driver)

[Philip Homburg]

I tried both FreeBSD-11.2-BETA2-amd64-bootonly.iso.xz and 
FreeBSD-11.2-BETA2-amd64-mini-memstick.img.xz on a Dell PowerEdge 2950 
BIOS version 2.7.0. With both images, the USB stick is not recognized.

For reference I tried an image for a random other OS and in that case the
USB stick is recognized.

I'll try to experiment a bit to see if I can find what causes the issue.
