Hello. as follow-up to recent discussion with your mail list, I would like to share the following correspondence from the FreeDOS mail list.
My Question re below info: Is it possible to use FLASHROM as advised below (USB drive) when infact it's not working from full OS environment? I think it is NOT possible, but want your confirmation.
BTW, I also booted into Ubuntu-Linux and tried the same flash - I get the same err as I did from FreeBSD O/S.

The USB drive has grub2 installed, I use it as a rescue drive & I can add menu items however I like. I am able to boot into FreeDOS from grub2 this way: linux16 (hd0,1)/boot/memdisk raw linux16 (hd0,1)/boot/FDOEM.144 When I boot into FreeDOS, only the contents of the mem-loaded image file (FDOEM.144) are visible. All the tutorials I have found confirm this behaviour by instructions to add BIOS-update-files into the FDOEM.144 file, so that the BIOS update files become available in the memory-file environment. MY QUESTION: Would it be possible to provide access from the FreeDOS mem-file environment to a folder on the USB drive? This way, one would boot into FreeDOS from grub2, chdir to the folder route defined in the FreeDOS config.sys (?) and run the dos-biosupdate.exe. If this is possible, one would just copy the BIOS files into the defined folder and be done with it. Instead, with current definitions one mnust loop-mount FDOEM.144, copy the BIOS files into a sub-folder, unmount FDOEM.144 and copy it to the USB drive.

Hello! You can try to use flashrom (http://flashrom.org) utility for that. See download link http://ra.openbios.org/~idwer/flashrom/dos - version for DOS Best regards, Anton Kochkov.
