No. Only 5.0. I have to build a 4.9 system then. Or I will try to
download older binary releases.

Hi,

I have tested SOEKRIS4521-50.image on a Soekris NET4511. The boot
sequence failed with this log :

Hi

I have committed several changes to kernel configurations for Soekris,
WRAP12, PCEngines and COMMELL-LE564 to make Flashboot work on OpenBSD
5.0. We are also not using svnd any more since it has been integrated
to vnd

Since I only have Soekris 4801 and there need to be more testing on
other platforms to verify that it work as expected. Please test and
report back to the list.

I will put binaries on github (https://github.com/openbsd/flashboot)
to night and the downloads will be available from the wiki page.

Best regards Johan

Hi.

I just added a new script to build image from OpenBSD install49.iso to
make a bootable USB installation pen drive.

The script is called build-usbinstallimage.sh

If any one could test the script I would be very happy. I have tested
it with both i386 and amd64 and it's possible to boot and install from
a usb stick. No more need to burn cd just for installations =)

There is how ever some kind of problem with OpenBSD own installation
script because it can't find the path to the files automatic since its
not from a CD. The path mounts upon question and the installation
proceeds without any problem.

Best regards Johan Ryberg

Hi.

According to TODO:
[snip]
load kernels as 16Mb
 - will avoid isadma problems
 - need to modify kernel and boot loader
[/snip]

Does any one has the status of this? I have not spent a single thought
about this during my work since all my test has worked and we are now
building a kernel that are 48 Mb in size and I have not found a single
downside yet and I have tested Flashboot on Soekris 4801, Virtual Box,
misc laptops and custom made computers. They all boot and works as
expected.

Maybe never versions of the boot loader that we are using today don't
have this limit and this TODO is some kind of forgotten note that just
should be deleted?

// Johan

Howdi folks

It's now possible to build a usb kernel and usb image.

I would love to see that some one tested the image. Binary download
can be found at github
(https://github.com/downloads/openbsd/flashboot/PENDRIVE.image) or
build by your self from scratch, it's all automatic =)

Best regards Johan Ryberg

Hi

I need some help with a problem.

The issue can be found here: https://github.com/openbsd/flashboot/issues/9

It's about booting Flashboot on a USB stick with a computer with a
SSD. Flashboot assumes that the USB stick has device sd0 but that
device is in fact the ssd drive.

Does any one have any idea how to solve this?

Regards Johan Ryberg

Hi,

Thanks to rancor there are now new binary images for 4.9 up on http://tilde.se/flashboot/ please test and
tell us if you find any bugs.

Kind Regards, Rickard.
