DragonFly doesn't boot on Sony Vaio
Sorry, pressed enter before ending the edit of the bug report.
Trying latest RELEASE (2.2.1) and the latest DEVEL ISO downloaded today from
here i'm unable to pass the boot loader.
What i can see is this (copied by hand).

DragonFly/i386 bootstrap loader, Revision 1.1

And then hangs forever.
I think it could be related to the fact that the cdrom is USB. I can't change
the legacy mode in the BIOS because there is no option for it.
The laptop is a Sony VAIO VGN-TZ21WN/b.
Thanks in advance.

This is the BTX Halted issue again. There is a fix available in smtms' repo
, but it still hasn't been commited to master.
It definitely solved my issue with BTX Halted and didn't notice any other

I don't know which specific patch you are referencing in that link
but I did commit the BTX boot loader real-mode changes to master.
Not sure if I MFC'd them to the release branch or not though.

I still think DragonFly needs GRUB. The fact that it is GPL licensed
probably discourages a lot of people but:
GRUB works on more hardware. Check
GRUB is easier to use. Check
GRUB is easier to configure. Check
GRUB will allow booting many more operating systems along side DragonFly.
GRUB community will give us upstream support with updates. Check
For once, the GPL vs BSD war should be put to bed, and we should use best
tools for the job.
My 2 cents.

Matt, you are right, I wasn't aware that it actually got committed, but I
don't think it was ever MFCed.
In any case, the original bug report is from before the commit, so it would be
worth a try for the reporter to try a current DEVEL release.
For reference, the relevant commit is:

if you think grub is up to the task and that there would be any advantage in
using it, feel free to:
a) start a discussion about it on users@
b) port grub to DragonFly and submit a patch once it works
I surely see right now more trouble than advantages in switching boot loader.
Apart from the fact that a part of the bootloader would need to remain,
because, afaik, grub doesn't support UFS, or booting BSD kernels or anything;
it'd need to chainload a BSD loader.
