Basic answer: The risk is similar in both cases.

Avoid emm386 / jemm386 / jemmex / USB drivers, try
to boot from something simple (floppy? cdrom/dvd?
maybe not USB?) to reduce load on BIOS built-in
USB drivers, maybe even use non-USB keyboard/mouse.

Actually better avoid mouse drivers for flashing
anyway. It might even make sense to avoid HIMEM /
HIMEMX as well and use FreeCOM 0.82pl3 command.com
instead of 0.84 or 4DOS or other modern shells...

Problem with flashing is that your BIOS is in a
state of transition. You just boot DOS to get the
BIOS update file to the BIOS update tool and then
you hope that nothing touches the BIOS or disk or
other hardware any more apart from the tool itself.

The best way to get this is to have no special
drivers (not even BIOS built-in ones) busy and
use a tool which does not access DOS while it
does the actual modifications. That said, most
BIOS flash tools are really simple for any DOS
and flashing should be safe enough as long as
you keep the number of drivers reasonably low,
disable energy saving features (in BIOS and in
FDAPM etc) and do not touch (mouse, network, USB,
keyboard...) the computer in the critical moment.

Hi. I want to flash new bios to my motherboard. Is it safe to use freedos
instead of msdos for bios flashing purposes? Are there any problems with
this?
