Eric Auer writes about this warning for ASUS motherboard users:
Hi, I got a complaint about a broken FreeDOS installer on a CD-ROM that seems to be shipped with ASUS P4PE motherboards:
German / English
They do not mention FreeDOS on the homepage, but I found 1 or 2 other, similar, complaints about "some FreeDOS program which comes with the P4PE", so I think SOMEBODY is bundling FreeDOS with that motherboard.
So here the warning: The (old) installer does not seem to work, and it might break your Windows if you boot from that CD-ROM.
I have already mailed the German ASUS support to ask for an explanation - offering to provide them a WORKING FreeDOS installer...
