[Plex86-devel] running win95 bochs image in plex86

[rohitash panda]

hi,
  pasted below are the errors i get while running a win95 image i 
created in bochs.i was getting the same
problems while using a win98 image created in bochs ( though i 
came to know from a gentleman that win98
currently cannot boot in plex 86) and i was also getting this same 
error while i tried to boot a linux image
i got from the bochs website.So i presume this error is not 
related to the images but its going wrong
somewhere else.I have tried to find out but could not till now , 
so anybody has any knowledge why it is
behaving like this ??
        I am sending all the errors i get and also the config file.
