Not exactly. Win95/98 had to maintain compatibility with a lot of hardware and softwre, and hence replicated *most* of the functionality of DOS into what they called if memory does not fail me "protected mode". However, from times to times they had to go all way down to protected mode, either for the real mode sound card drivers, or for an hard disk that had not the 32 bit "mode" activated, or for a TSR or a virus you had running (no kidding)...shit like that. And Win95 depended a lot on real mode for I/O at least, the situation was only slightly better under win 98. The 95 does not running and needing DOS was a lot of BS talk from MS.
