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

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
