Marcus,

that work sounds great!
Can you explain a little more, how to use, what to setup, what should work
now, what could work soon and what still needs a lot of work or is 
unreachable?

Bye

There is no need for any setup.

secdrv.sys of InstallShield just requires some functions of ntoskrnl.exe, which
I have implemented to a degree it that it functions.

As of working, in Need for Speed v4 from Electronic Arts I now see the SafeDisc[tm]
Splashscreen, then it is seeking on the CD pretty heavily, then the program terminates.

So consider the first step towards SafeDisc support done as soon as they are 
merged to CVS.

Ciao, Marcus

For the record (we already discussed this a bit on IRC) this is probably
SafeDisc taking seek-time profiles from the CD drive. SafeDiscs contain
certain blocks in unusual widely-spaced ordering that is not possible to
recreate using standard CD burners. By reading each block in turn and
checking that the seek times are high enough they can verify the CD has
not been copied using consumer-grade equipment.

This test, in other words, should pass - as long as the Linux/Wine CD
subsystems have similar timing profiles to Windows (gulp)

thanks -mike

There are several safedisc versions. What you are saying is applied
to safedisc 2.6 and newer, but it is not necessary for safedisc 1.x
or 2.0.
