I am trying to crack a dos program. I use soft-ice v2.08. How ever the program can't work correctely by another program control the extended memory. Can I load the soft-ice in the lower memory?

Hello robertyonghu !

You have to load SoftICE as a device driver in the CONFIG.SYS.
You must not load HIMEM.SYS, EMM386.EXE, QEMM386.SYS or any other memory manager.
You must load it before any other Device, DeviceHigh, Install or InstallHigh command.

Please read the documentation about the commandline options of SoftICE.

I have maneged to let the program compatible with softice, However I haven't got documentation for this verson softice. Will you please send a copy to me? my email is robertyonghu@yahoo.com. thank you!

Hello robertyonghu !

Sorry, but I don't have the documentation for SoftICE 2.08.
I suggest to search the internet for SoftICE 2.80. It includes the documentation and CONFIG.SYS samples. There are two versions going around. One is from the original from SoftICE Suite, one is hacked by someone. (As far as I remember. I've just debugged one time with SoftICE for DOS )

Answer to your post in the Newbies Forum:

You can change the behavior of Windows starting a program in a DOS session by editing it's .PIF file.
I've never seen anything in Fortran, so I can't help you here.

Heya,
soft-ice v2.08 or soft-ice v2.80 works only on dos 6.22
you can load the dos program in windows dos prompt mode
c:\*.*\siw95\util16\dldr 'your dos program'
