Hi All!
Some time ago I was reversing old DOS program. To load program to Sice I used dldr.exe (DS 2.7 and Win2k Pro) and noticed that loader doesn't work. Sure, the Sice was patched. To solve that problem I dissassembled dldr.exe to determine what method it uses to connect with Sice. Simple string search like "NTICE" etc. gave me nothing. So the question is: How to patch dldr.exe and can anybody explain how exactly it detects if Sice loaded or not?

Hi
does the dos program run in winxp?
No point to patch dldr coz it only runs on dos orwin9x

As I mentioned above my configuration is Driver Studio v2.7 and Win2k SP2. When Sice isn't hidden, I mean when it is not patched in any way, dldr runs well. But it fails to load when Sice patched. So the question remains.
