Hi All:

We have a OEM low power i7 based box that is to run Win7 on it....
i need to flash the bios, the thing haev no CD or floppy..... need to do it from USB and ITS A DRAMA!

UNetbootin no longer works, its gone for shit. I've have problems with it doing bootable linux....

So, I've used UNetbooin to try and make a bootable Freedos USB.
I get this on the target machine:
Could not find kernel image: menu.c32

Ok, here is the sysllinux.cfg thet UNet wrote onto the USB:
default menu.c32
prompt 0
menu title UNetbootin
timeout 100

label unetbootindefault
menu label Default
kernel /ubnkern
append initrd=/ubninit

All well and good, except for one problem....there is no file /ubnkern on the USB stick. Only these files are there:
jserink@jserinki7 /run/media/jserink/B802-1D2D $ ls -l
total 1456
-rw-r--r-- 1 jserink jserink 145 Oct 13 17:15 syslinux.cfg
-rw-r--r-- 1 jserink jserink 1474560 Oct 13 17:15 ubninit

Anyone know how to make this boot into DOS?

Cheers,
John

I would skip unetbootin - when it works it works well, but when it doesn't work you're probably better off just giving up on it.

Try the instructions here: http://freedos.sourceforge.net/wiki/index.php/USB

Hi BradN:

Tried that link, crashed ab burned.

I ended up here:
http://www.chtaube.eu/computers/freedos/bootable-usb/

Downloaded the 2G image, it worked a treat.

Copied my FW directory over and we're sweet!

Thanx for the heads up in getting me to the right place.

Cheers,
john

Unetbootin work for me when the Usb key have no partition table. I force mkdosfs to format the whole key in Fat with the -I (like Icone) option. Example with sdb as the Usb key
Code:
mkdosfs -F 32 -I -n Unetbootin /dev/sdb

After mounting the key, and Unetbootin finish the install, the key boot properly.
