Hardware-level break points MagicCV uses advanced features of the 80386 REAL-TIME break points on memory locations, memory ranges, microprocessor to load Code View and symbols in execution, I/O ports, hardware and software interrupts. More extended memory. This allows MagicCV to run powerful break points than ANY software-only debugger on the Code View using less than 8K of conventional market. Soft-ICE gives you the power of an in-circuit emulator on memory on your 80386 PC. your desk. Don't let 640K be your limit! Break out of hung programs If you are closing in on the 640K limit and would With a keystroke - no external switch necessary. Even with like the power of Code View, MagicCV is for you. interrupts disabled. Don't let the debugger hide the bug! Breaks the 640K barrier Even if you're not closing in on the 640K limit, Soft-ICE uses ZERO bytes of memory in the first 1MB of address running Code View with MagicCV makes your space. This is especially useful for those subtle bugs that change debugging environment much closer to the end when the starting address of your code changes. With Soft-ICE user's program environment. You can use your code executes at the same address whether the debugger is Code View to locate subtle bugs that only occur when there is plenty of free memory, or those loaded or not. difficult bugs that only occur when your program Works with your favorite debugger is running with a couple of TSRs loaded. Soft-ICE can be used as a stand-alone debugger or it can add its powerful break points to the software debugger you already use. How MagicCV works You can continue to use your favorite debugger until you require MagicCV uses the 80386 to create a separate virtual machine for Code View. MagicCV uses Soft-~CE. Simply pop up the Soft-ICE window to set powerful real-tIme break points. When a break point is reached, your between 4K & 8K of conventional memory as a debugger will be activated. bridge between the DOS environment and CodeView. Solve tough systems problems too MagicCV is easy to use Soft~ICE is ideal for debugging TSRs, interrupt handlers, self bootmg programs, DOS loadable device drivers, non-DOS Ifyou are a Code View user, you already know how operating systems, and debugging within DOS & BIOS. Soft-ICE to use MagicCV too. Just type MCV instead of is also great for firmware development because Soft-ICE's break CV; everything else is automatic.
