I have several DOS programs which run excellent under real Win XP, but under virtual XP they run faulty. These Programs find existing files, but report some of them twice (instead of once).
To find existing files they use DOS Intr 21H, AH=4E (FindFirst) and 4F (FindNext). Under virtual XP typically the first 7 or 8 files or directories are reported twice, the rest is then ok. On drive C: the bug does not exist, only on the other drives, which are mapped to the host network like.
An old Norton Utilities Tool shows exactly the same bug. Under real XP everything is perfect.
Please can anybody help?
Host is Win 7 SP1 Home Premium 64 bit
Guest ist Win XP SP3
VMware is 5.0.2
Logfile shows nothing at that time.
