ICECREAM.ZIP ICECream - SoftICE '95 Detection A friend of mine, Per Mellstrand (author of ShellWizard 95), was kind of annoyed of people poking in his program. He guessed that the main tool people used to "break into" his software, was SoftICE from Nu-Mega. What he wanted was a nice way to detect that SoftICE was running. I found it. A nice way to detect SoftICE '95 is as follows: * Get the Interrupt Descriptor Table (IDT) with assembler command SIDT * Get the address of Interrupt gate 1 * Move 16 bytes back * Check if the four bytes at this position is "V101" - if so, SoftICE is running!

The Netwide Assembler grew out of an idea on comp.lang.asm.x86 (or possibly alt.lang.asm, I forget which), which was essentially that there didn't seem to be a good free x86-series assembler around, and that maybe someone ought to write one.
