[Plex86-devel] Bochs Fun....

[Drew Northup]

What version of Bochs are you running?  Versions since 1.2 don't use raw
disk images (actual raw device files--MBR and all) right for some
reason--therefore if you built the image using a newer version of Bochs,
it WILL NOT WORK!
I have complained about this to the Bochs folks on several occasions, and
they seem to think that I should abandon the way that Kevin Lawton,
myself, and several university professors spent a good couple months
arguing about.  In any case, use an older version of Bochs to do the
installs for plex86 disc images for now.  Maybe in the near future the
Bochs folks and us over here will be able to make a good compromise on
disk images (support for both raw and Bochs "cooked" disk images, on both
projects)--until then you'll have to find an older version of bochs and
use that.
